border="0" /&gt;&lt;/a&gt;Here in the Phoenix metropolitan area, adverse water conditions require intelligent water treatment strategies to adequately maintain water cooled equipment. Proper management of the characteristics of the cooling tower sump water along with maintaining good tower hygiene in general accomplishes at least four positive things.&lt;/div&gt;&lt;div style="text-align: justify;" id="body"&gt;&lt;p&gt;1) It avoids wasting excess water.&lt;br /&gt;&lt;br /&gt;2) It inhibits scale formation.&lt;br /&gt;&lt;br /&gt;3) It controls biological growth.&lt;br /&gt;&lt;br /&gt;4) It reduces the corrosion rate of metal parts in the tower.&lt;/p&gt;&lt;p&gt;Let's discuss how a cooling tower operates to understand why proper water treatment is important.&lt;/p&gt;&lt;p&gt;Most residents in the valley are familiar with an evaporative cooler. Water from the evaporative cooler sump is circulated by a pump over pads in the evaporative cooler and outside air is drawn through the pads. As the air is drawn through the wet pads some of the water evaporates and cools the air. The cooler air is then circulated into the space where cooling is desired. In the process of cooling the air, the water being recirculated across the pads is also cooled.&lt;/p&gt;&lt;p&gt;That is exactly the same principle being employed in the cooling tower, but on a much grander scale. Rejecting large quantities of heat from a building's mechanical system requires a lot of water to be evaporated. For example, a one hundred ton water cooled chiller operating at full capacity for 24 hours would require the evaporation of more than four thousand gallons of water. That brings us to the subject of the characteristics of the make up water. Make up water is the water supply that replaces the water being evaporated in the cooling tower.&lt;/p&gt;&lt;p&gt;Here in the metro area, water conditions vary widely because our water comes from several different wells as well as surface sources. The water quality may change rapidly over a short period of time because different sources are utilized for the water supply. Each well has different water characteristics and they often vary widely from one side of town to the other. Water that comes from surface sources, like the Central Arizona Project will usually have significantly different characteristics than well water. Surface water quality may also be influenced by weather conditions such as drought or increased runoff.&lt;/p&gt;&lt;p&gt;As water evaporates in the cooling tower all of the non-volatile components stay behind in the sump of the cooling tower. There is actually a lot more in water than what we would call hardness (carbonates). There are also chlorides, suspended dust particles and biological microorganisms. As more and more water is added to replenish the water that is being evaporated, these dissolved and suspended components in the sump water continue to accumulate. If no measures are taken to control the concentration of these components in the water, the solution eventually increases in concentration to a point where "stuff" starts coming out of solution. This "stuff" ends up getting deposited on the surfaces that the water comes in contact with.&lt;/p&gt;&lt;p&gt;Have you ever seen an evaporative cooler where the pads haven't been changed for a long while? I've seen them so encrusted with mineral deposits that the blower could no longer pull air through them. I've also seen them produce a bounty of biological growth in the sump water. That is exactly what will happen in a cooling tower without adequate attention to hygiene and an appropriate water treatment strategy.&lt;/p&gt;&lt;p&gt;When solids that are dissolved in water come out of solution they are deposited first on heat exchange surfaces and surfaces where the water is being evaporated. Heat exchangers, water cooled condensers, drift eliminators, the tube bundle in closed circuit cooling towers and the fill in open cooling towers are a few examples of surfaces where this occurs.&lt;/p&gt;&lt;p&gt;Deposition of mineral scale, dirt and biological fouling on any heat exchange surfaces can result in reduced heat transfer, reduced tower efficiency and increased energy costs. While reducing deposition of these is important with regard to the cooling tower, it is absolutely critical to avoid scaling or fouling in the water cooled condenser. Scaling and fouling in the condenser significantly reduces heat transfer capability and will seriously impact energy costs, performance and reliability.&lt;/p&gt;&lt;p&gt;A two part strategy is usually employed to manage the mineral content of the sump water. Part one is to maintain the sump water pH within allowable limits and to feed the correct type and amount of chemicals to help the water keep more of the dissolved solids in solution. Part two is intentionally sending some of the sump water down the drain (blow down). Blow down reduces the highly concentrated mineral content of the sump water by diluting it with the fresh make up water being added to replace the intentionally wasted water.&lt;/p&gt;&lt;p&gt;Biological growth can also become a significant health risk depending on the particular organism involved. Allowing mud and biological growth to accumulate in the sump of a cooling tower can accelerate corrosion of the sump and shorten the life cycle of the cooling tower. It can also provide a haven for microbes to escape the effects of a biocide.&lt;/p&gt;&lt;p&gt;Proper water treatment strategy and good cooling tower hygiene is not a one size fits all solution. The quality of the make up water will require an adjustment of the type of the chemicals and biocide utilized. It may also require changing feed and blow down rates for proper control. In addition, these requirements may be altered by the characteristics of each individual cooling tower installation.&lt;/p&gt;&lt;p&gt;According to Alan Bateman of DB Water Technologies, there are several things a good cooling tower water treatment program should address in order to be effective. They are total dissolved solids (TDS), hardness, pH, chlorides, suspended solids, an appropriate method for biological control and a proper blow down strategy. Each cooling tower manufacturer publishes recommendations for maintaining proper water conditions of the sump water. The advice of a qualified water treatment professional is advised to ensure that each item above is included in your overall strategy for cooling tower water &lt;a href="http://premature-ejaculation-treatments.net/"&gt;treatment&lt;/a&gt;.&lt;/p&gt; &lt;/div&gt;&lt;div style="text-align: justify;"&gt;                    &lt;/div&gt;&lt;div style="text-align: justify;" id="sig" class="sig"&gt;       &lt;p&gt;Mark Strahan is a 35 year veteran of the HVAC industry and is currently an account manager with Burt-Burnett, Inc., an HVAC mechanical service and EMS controls contractor.

This naturally occurring airborne contaminant (generated by the Poplar Tree) usually effects operations from May thru early August, hence, companies that rely upon process cooling must clean their equipment frequently during this period or risk failure. Then comes the dog days of summer when insects, paper, construction debris, birds and just about everything that blows in the wind seems to find its way into your cooling equipment, then comes the final seasonal assault during the fall season when the trees drop their leaves, scattering them to the wind where they always seem to find their way to your condenser coils and cooling towers.&lt;br /&gt;&lt;br /&gt;Keeping up with HVAC maintenance during the spring, summer and fall is nearly a full time job for most production operations and as the economic realities of business cause maintenance budgets and staffing to be reduced, it is increasingly important that companies find effective maintenance solutions that will streamline their day to day HVAC maintenance activities and enable them to more effectively handle work loads with fewer people and with fewer budget dollars.&lt;br /&gt;&lt;br /&gt;Think about it, if you are in a lean maintenance staffing situation and you had five things to do on any given day and one of the tasks was cleaning condenser coils and cooling towers, how high on the "To Do List" would it rank? Given that it's time consuming and hard, dirty work, most people would rank it pretty low; Unfortunately, if the equipment is in need of cleaning and maintenance continues to be delayed, no reason for delaying it will change that fact and the equipment will continue to operate at an increasing level of inefficiency until the equipment can no longer support the cooling requirements.&lt;br /&gt;&lt;br /&gt;Now consider the same list of five things to do except this time cleaning cooling towers and chiller coils only took a few minutes per unit using a broom, now where would this task would fall on the "To Do List"? Well, there's no real way of knowing, but the likelihood of it ranking high on the list is pretty good. Furthermore, if cleaning the equipment was as easy as using a broom or rinsing with a garden hose and it didn't require opening or disassembly of the equipment, then nearly anyone could perform the maintenance and that would change the dynamics of the HVAC / Cooling tower maintenance process.&lt;br /&gt;&lt;br /&gt;How to Change the Dynamics of the Maintenance Process.&lt;br /&gt;Air Intake Filtration specifically engineered for use on condenser coils, cooling towers and other HVAC equipment is one of the best ways to prevent fouling of your equipment. Unlike window screen, bug screen, shade screen and conventional filters including roll media, pleated filters and electrostatic filters which are largely designed for internal use on air handling units and forced air heating systems, Air intake filters are specifically designed to mount to the outside of the equipment where it stops airborne debris before it enters your system and where it can be easily seen and quickly removed using a broom, brush, shop vacuum or by simply rinsing with a garden hose - Even the rain has a cleansing effect on air intake filters and they never need to be removed for cleaning. Furthermore, because of the critical airflow requirements on cooling towers, and air cooled chillers, air intake filters are specifically engineered to be nearly invisible to the airflow on high volume / high velocity air flow systems (static pressure drop is less than 1/10" w.g. at 600 fpm air velocity).&lt;br /&gt;&lt;br /&gt;So What's The Big Deal About Air Intake Filtration? Air Intake Filters help eliminate the "hassle factor" by dramatically reducing HVAC maintenance time and effort - but the benefits don't end there; here's what else they will do to save budget dollars and change the dynamics of your maintenance process:&lt;br /&gt;&lt;br /&gt;Condenser Coil Filter Screens -Benefits&lt;br /&gt;&lt;br /&gt;* Prevents debris from getting into coils.&lt;br /&gt;* Reduces / eliminates annual pressure washing&lt;br /&gt;* Reduces / eliminates need for cleaning chemicals&lt;br /&gt;* Helps reduce energy cost because coils stay clean all season long.&lt;br /&gt;* Dramatically reduces maintenance, repairs, downtime and lost productivity.&lt;br /&gt;&lt;br /&gt;Cooling Tower Filter Screens - Benefits&lt;br /&gt;&lt;br /&gt;* Reduces / eliminates sludge build-up in the basin by significantly reducing bio-loading.&lt;br /&gt;* Prevents fouling of fill.&lt;br /&gt;* Prevents plugging of strainers, blow-down valves and heat exchangers.&lt;br /&gt;* Helps reduce algae growth by diffusing sunlight, which supports photosynthesis.&lt;br /&gt;* Reduces water treatment chemical consumption due to reduced bio-loading.&lt;br /&gt;* Dramatically reduces maintenance and repair cost, downtime and lost productivity.&lt;br /&gt;&lt;br /&gt;Air Solution Company developed and patented the first Air Intake Filter specifically engineered to mount to the outside of cooling towers and other HVAC equipment for purposes of stopping the debris before it entered into the system. Since that time, Air Solution Company has been manufacturing and has introduced a variety of other innovative filter systems including its new Fine Mesh Filter which is engineered for use on small and medium size refrigeration coils and machine fan intake housing units.

The water carries bacterial growth in it whether it flows through the faucet or if it is flowing through a cooling tower. If this water is not treated as soon as possible, it can rust and corrode and deposits will form inside the water treatment equipment. This reason makes the cooling tower water treatment system so very important.&lt;p&gt;&lt;b&gt;Problems From Not Maintaining The Cool Tower&lt;/b&gt;&lt;/p&gt;&lt;p&gt;When you do not keep up the proper maintenance on you cooling tower water system, you will find that many different problems will come up. These problems can include scale formation, corrosion, and biological fouling.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Problems With Scale Formation&lt;/b&gt;&lt;/p&gt;&lt;p&gt;Scale is what is formed when wet solids get clogged in the pipes. This scale is made from heat and cold water that contains a very high mineral content. These deposits will continue to build up over time. If these scale deposits start to form on a heat exchange surface, they will eventually clog the passages and slow the system down. The cooling tower can also be affected by the scale deposits. If the deposits block the flow of the basin or fill in the cooling tower, problems arise.&lt;/p&gt;&lt;p&gt;Choosing to use a cooling tower water treatment system will help to stop the problems of scale deposits. It is a very budget friendly way for you to treat the problems you are having but also to lower the maintenance and the cost of maintenance on the cooling tower system itself. The majority of money that is spent each year is on the removal of the scale deposits from the inside.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Inside Corrosion&lt;/b&gt;&lt;/p&gt;&lt;p&gt;When metal starts to dissolve, you have what is known as corrosion. Oxidation effects break the metal down significantly. The breakdown will cause the system to degrade at a faster rate than normal. The major point being that when the metal starts to break down, the strength of the metal and the thickness off the metal are reduced. The structure of the metal can no longer stand up to the pressure that it was designed for and pits and craters can form in the metal.&lt;/p&gt;&lt;p&gt;A cooling tower system will help to stop the corrosion from happening. The better of the treatments for corrosion is the ozone treatment. There are also other methods that work just as good.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Problems With Biological Fouling&lt;/b&gt;&lt;/p&gt;&lt;p&gt;Problems with biological fouling occur when the water has not been used and left for long periods of time. When the water is left unattended, it has the potential to form bacteria, fungus, algae, and protozoa. The microorganisms will eventually get to large proportions in the water and will cause a biological film to form on the surface of the water. This film is very hard to get rid of. This is what is known as biological fouling.&lt;/p&gt;&lt;p&gt;The biological fouling problems are commonly known to be the worst problem that you can encounter with the cooling tower system. The problems that can occur with biological fouling are low heat transfer, the fill can stop working properly, the water flow can be restricted or blocked, or corrosion can occur from the microorganisms present. It can also result in health problems for the humans that are using it.&lt;/p&gt;&lt;p&gt;The use of a &lt;a target="_new" rel="nofollow" href="http://www.ewatertreatmentsystems.com/watertreatment/Buy_water_treatment_online.html"&gt;cooling tower water&lt;/a&gt; system helps to get rid of this particular problem. When you purchase a good system, it will remove the bacteria, viruses, fungus, and any other organisms that should not be in the water. The cooling system will help the fouling that is a problem with the biological affects in the water to not occur. When these nasty things are removed from the water, it will definitely improve the quality of the water and also the flow of the water through the tower.&lt;/p&gt; &lt;/div&gt;&lt;div style="text-align: justify;"&gt;                    &lt;/div&gt;&lt;div style="text-align: justify;" id="sig" class="sig"&gt;       &lt;p&gt;You can also find more information on &lt;a target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/water_filtration_for_drinking_purification.html"&gt;drinking purification&lt;/a&gt; and &lt;a target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/water_treatment_online.html"&gt;water treatment&lt;/a&gt;. eWaterTreatmentSystems.com is a comprehensive resource for water treatment with information on reviews, reverse osmosis and how it works.&lt;/p&gt;     &lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1716469170445491974-2009807637500761013?l=cooling-tower.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cooling-tower.blogspot.com/feeds/2009807637500761013/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1716469170445491974&amp;postID=2009807637500761013' title='3 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/2009807637500761013'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/2009807637500761013'/><link rel='alternate' type='text/html' href='http://cooling-tower.blogspot.com/2010/02/important-information-on-cooling-tower.html' title='Important Information On The Cooling Tower Water Treatment'/><author><name>alzack</name><uri>http://www.blogger.com/profile/17521948257526887706</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://4.bp.blogspot.com/_QgQkmyCHz1Q/S273GD_fLnI/AAAAAAAABpU/BPMSqF7Haa8/s72-c/cooling-tower.jpg' height='72' width='72'/><thr:total>3</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1716469170445491974.post-530738525309633730</id><published>2009-06-24T06:36:00.000-07:00</published><updated>2011-03-05T07:18:01.784-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Chillers'/><title type='text'>How Free Cooling Can Save You Money</title><content type='html'>&lt;div style="text-align: justify;" id="body"&gt;&lt;p&gt;What is free cooling and how can it save you money and help with the environment. Well free cooling is an economic method of using low external air temperatures to help with chilling the water, it also can then be used for an industrial process. Or with the air conditioning systems in the green data center.&lt;/p&gt;&lt;p&gt;When it is cold outside you can help save energy with your chilled water system. You can do this by adding a plate-and-frame heat exchanger. What this does is provide chilled water production. All that really means is you can shut down the chillers compressor.&lt;/p&gt;&lt;p&gt;When you add a plate-and-frame heat exchanger it can save you so much energy costs that you can earn your money back from the plates' installation in about two years. The right time to put on the plate is when the temp outside reaches below the temp that the water required set point. It can save your business money and it is also good for the environment because you are using less energy to run your chilled water system.&lt;/p&gt;&lt;p&gt;If your water chiller is being run mechanically, and it is only being used to maintain a specific maximum humidity condition that would not be able to be done with indirect cooling, it can double your energy cost. Because then you can set the water chiller to the outside dew point, that will be satisfactory to your laboratory conditions.&lt;/p&gt;&lt;p&gt;You can use the plate and frame system when the chilled-water return temperature is greater than the cooling tower's supply water temperature. This method can save you evaporative cooling opportunities and it can also reduce the chillers function by one-third to one-half.&lt;/p&gt;&lt;p&gt;You do not need to produce more cooling than you actually need. When you produce more than what you need it wastes money and energy. Variable speed drives can vary the output of your water chiller that will help to meet your needs throughout the day. This will help you save money on energy costs.&lt;/p&gt;&lt;p&gt;It is also important to have the right sized unit installed. You have a very skilled employee at your company who you depend on to adjust the flow of the water or tower water in an effort to provide enough cooling? Chiller technology can take care of the problem. When you properly install the right sized chiller installed, you simply set the chiller temperature and the solid state "genius" inside the chiller maintains your constant source of chilled water.&lt;/p&gt;&lt;p&gt;With today's economy everyone is looking to save money this is a great way to do it. And it also helps you become more earth friendly. &lt;/p&gt;&lt;/div&gt;&lt;p style="text-align: justify;"&gt;&lt;a id="link_89" target="_new" href="http://www.loikits.com/"&gt;process chillers&lt;/a&gt;, &lt;a id="link_90" target="_new" href="http://www.loikits.com/"&gt;chiller&lt;/a&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1716469170445491974-530738525309633730?l=cooling-tower.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cooling-tower.blogspot.com/feeds/530738525309633730/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1716469170445491974&amp;postID=530738525309633730' title='1 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/530738525309633730'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/530738525309633730'/><link rel='alternate' type='text/html' href='http://cooling-tower.blogspot.com/2009/06/how-free-cooling-can-save-you-money.html' title='How Free Cooling Can Save You Money'/><author><name>alzack</name><uri>http://www.blogger.com/profile/17521948257526887706</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1716469170445491974.post-191647018721568117</id><published>2009-06-04T08:07:00.000-07:00</published><updated>2011-03-05T07:18:50.431-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Cooling tower parts'/><title type='text'>Cooling Water Filtration - What is the Purpose?</title><content type='html'>&lt;div style="text-align: justify;" id="body"&gt;&lt;p&gt;In almost all of the industrial processes and manufacturing, water plays a basic role. It helps in cooling as well as cleaning but when this water becomes polluted it really damages the efficiency of the system by delaying the process and ultimately the quality of the product is affected.&lt;/p&gt;&lt;p&gt;This problem can be solved nowadays by a technology called cooling water filtration that removes suspended solids from cooling systems efficiently.&lt;/p&gt;&lt;p&gt;In this method untreated water is passed through a membrane which sends steam to another filtration device in order to clean it thoroughly. After that water is passed through the filtration equipment and there it cools down.&lt;/p&gt;&lt;p&gt;Cooling water filtration is used in commercial buildings, cooling towers, and closed loops and plays a vital role just as the lungs play an important role in the functioning of our body and are effective in removing deposits of corrosion and scaling.&lt;/p&gt;&lt;p&gt;In commercial buildings, the cost that water treatment systems bear is very small compared to the cost of water and other utilities. However these filtration systems help in reducing problems of fouling and corrosion that take place because of some deposits like calcium carbonate that acts as a bacterial slime that often results when that particular surface comes in contact with water.&lt;/p&gt;&lt;p&gt;Cooling water filtration is also used in cooling towers where water is taken from inadequate sources and requires sedimentation. A cooling tower allows water to pass through an air stream then it is cooled down. The working of a cooling tower depends upon the quality of water. If water is contaminated, the efficiency of these cooling towers is decreased which sometimes leads to system failure.&lt;/p&gt;&lt;p&gt;The installation of these systems in your condenser or blocked loop systems not only helps to hold large course rates but also removes dirt and sediments from your cooling system thereby increasing its efficiency.&lt;/p&gt;&lt;p&gt;Some cooling water filtration systems do not completely remove all the contaminants from water; you have to make sure about the efficiency of the system you are going to install. You can also use surfactants and dispersants, and chemicals to maximize the efficiency of your system but it largely depends upon the nature of water that circulates in a system.&lt;/p&gt;&lt;/div&gt;&lt;p style="text-align: justify;"&gt;&lt;a id="link_89" target="_new" href="http://www.safe-water-purifier-resource.com/"&gt;Click Here&lt;/a&gt; to discover the shocking reality about the many traces of harmful contaminants in our water supply.

It wipes out all the competition when it comes to chilling - thus the name 'Iceberg'.&lt;/p&gt;&lt;p&gt;&lt;span style="font-weight: bold;"&gt;Neat and Fresh Accessory Kit:&lt;/span&gt; tired of untidy looking poly bags in your refrigerator? Throw them away right this minute we say! The unique Neat and Fresh Accessory Kit is designed in such a way that it would maintain your vegetable accessories in a neater and eye appealing manner. Also faster to sort and pick!&lt;/p&gt;&lt;p style="font-weight: bold;"&gt;User-friendly Features&lt;/p&gt;&lt;p&gt;&lt;span style="font-weight: bold;"&gt;Auto Cool System:&lt;/span&gt; The &lt;a id="link_92" target="_new" rel="nofollow" href="http://www.naaptol.com/buy-online/WO-shopping-best-deals-W77O/kitchen_appliances/refrigerators.html"&gt;Refrigerator&lt;/a&gt; is equipped with a unique auto cool feature which automatically sets it in an auto cool mode according to the need.&lt;/p&gt;&lt;p&gt;&lt;span style="font-weight: bold;"&gt;Deodorizer:&lt;/span&gt; This feature takes away the entire odor from your refrigerator keeping the stuff stored in your refrigerator fresh and great smelling for long.&lt;/p&gt;&lt;p&gt;&lt;span style="font-weight: bold;"&gt;Magic Light:&lt;/span&gt; Troubled by insufficient light in your refrigerator? The Magic Lights in your Iceberg will give you a proper and clearer vision in the refrigerator with a beautiful glow to please your eyes.&lt;/p&gt;&lt;p&gt;&lt;span style="font-weight: bold;"&gt;Door Lock and Beautiful Finishes : &lt;/span&gt;The Iceberg comes in a range of exciting finishes and is also equipped with a door lock to prevent your naughty kids to lay hands on overdoses of that yummy treat hidden in you refrigerator!&lt;/p&gt;&lt;p style="font-weight: bold;"&gt;Storage&lt;/p&gt;&lt;p&gt;The fridge is equipped with a total of 12 adjustable shelves and boxes which give you ample space to store and organize your stuff in a more convenient manner. The refrigerator has divisions like egg tray, chocolate tray, fruit box, covered vegetable box and separators in bottle and shallow bins which hold the stuff from falling off and also give you more organized storage.&lt;/p&gt;&lt;p style="font-weight: bold;"&gt;Conclusion&lt;/p&gt;&lt;p&gt;Even though the Whirlpool Iceberg 310 L Elite emerges as a clear winner when it comes to faster bottle chilling and ice making and also provides you with very good storage solutions, it does lack a few features like the open door alarm , flexi chill, moisture control, Magi Fresh and Freshonizer technologies etc. However, it is also in the medium price range and thus justifies its cost. At the end of the day however, it is for you to decide that what your priorities are when it comes to choosing a refrigerator and select the one that suites you the most. All in all, it is a good choice.&lt;/p&gt;&lt;/div&gt;&lt;p style="text-align: justify;"&gt;Vinnit Alex is a well known author and has written articles on &lt;a id="link_93" target="_new" href="http://www.naaptol.com/buy-online/WO-best-deals-shopping-W1592O/consumer_electronics/kitchen_appliances/refrigerators/whirlpool__genius_royale.html"&gt;Whirlpool Refrigerator&lt;/a&gt;, Kitchen Appliances store, Samsung Washing Machine, online shop and many other subjects.&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1716469170445491974-7594962113853224137?l=cooling-tower.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cooling-tower.blogspot.com/feeds/7594962113853224137/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1716469170445491974&amp;postID=7594962113853224137' title='1 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/7594962113853224137'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/7594962113853224137'/><link rel='alternate' type='text/html' href='http://cooling-tower.blogspot.com/2009/04/whirlpool-iceberg-310-elite.html' title='Whirlpool Iceberg 310 Elite'/><author><name>alzack</name><uri>http://www.blogger.com/profile/17521948257526887706</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1716469170445491974.post-6217252630953845860</id><published>2009-04-03T08:16:00.000-07:00</published><updated>2009-04-03T08:17:19.059-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Chillers'/><title type='text'>Process Chillers - Process Chiller Basics</title><content type='html'>&lt;div id="body"&gt;&lt;p&gt;Water chillers are used in just about every industry where a component, be it machinery or product, needs to be cooled. Sometimes, however, simple water chillers are not strong enough, and a process chiller may be used. Process chillers differ from standard HVAC chillers in that they use refrigerant coolants like ammonia and halocarbons, and can provide a higher level of cooling capabilities than standard chillers. In this article, we'll take a look at some of the basic information regarding process chillers and how they are used in today's industries.&lt;/p&gt;&lt;p&gt;Process chillers are generally made up of four parts - compressors, evaporators, condensers, and metering devices. The refrigerant is sent to a heat source by a compressor, where it absorbs the heat because of its chemical properties. It then carries this heat to an evaporator, where it undergoes a phase change - it is converted into gas form and thus disperses the heat into the atmosphere, sometimes through a cooling tower to provide extra heat absorption. The condenser then turns the coolant back into a liquid form and sends it back to the compressor, where it is pushed through the cycle again. Metering devices provide a way to regulate the amount of flow and heat being absorbed.&lt;/p&gt;&lt;p&gt;Process chillers are used in a number of industrial applications, such as in the plastics industry, where they are used to reduce cycle times in injection molding by regulating the temperatures there. They are used in baking and other foods, because cooler water allows dough to be mixed for longer periods and thus increases the quality of the product, and can cool various food producing processes such as the creation of chocolate, meat massaging, and vegetable processing. It is used in pharmaceuticals, where emollient vats produce large amounts of heat and frequently disperse it through a process chiller. They are even used in printing applications, to regulate temperatures in rollers and presses to reduce stretching and bleeding.&lt;/p&gt;&lt;p&gt;A process chiller can provide a large amount of cooling to virtually any facility, with the ability to chill up to forty tons of water or other refrigerant at a time. There are various types of process chillers available, with different types of compressors and coolant systems, each with their own strengths and weaknesses. The important thing is to know how much water you need cooled and at what rate, so that you can properly assess the type of cooling you will need.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;&lt;a id="link_83" target="_new" href="http://www.loikits.com/"&gt;Process chillers&lt;/a&gt;, &lt;a id="link_84" target="_new" href="http://www.loikits.com/"&gt;chiller&lt;/a&gt;, &amp;amp; chiller and compressors.&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1716469170445491974-6217252630953845860?l=cooling-tower.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cooling-tower.blogspot.com/feeds/6217252630953845860/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1716469170445491974&amp;postID=6217252630953845860' title='1 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/6217252630953845860'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/6217252630953845860'/><link rel='alternate' type='text/html' href='http://cooling-tower.blogspot.com/2009/04/process-chillers-process-chiller-basics.html' title='Process Chillers - Process Chiller Basics'/><author><name>alzack</name><uri>http://www.blogger.com/profile/17521948257526887706</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1716469170445491974.post-7921275707773654380</id><published>2009-03-25T07:18:00.001-07:00</published><updated>2009-03-25T07:18:34.508-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Cleaning cooling tower'/><title type='text'>What Are Cooling Towers?</title><content type='html'>&lt;div id="body"&gt;&lt;p&gt;What exactly are cooling towers anyway? They are heat rejection devices used to extract waste heat into the air from the cooling of a water stream to a lesser temperature. They are also referred to evaporate heat rejection devices. These devices provide lower water temperatures than an air cooled or heat rejection devices.&lt;/p&gt;&lt;p&gt;Cooling towers are used in air conditioning, electric power generation and in various manufacturing facilities. They can be referred to both open circuit and closed circuit heat rejection equipment.&lt;/p&gt;&lt;p&gt;Small cooling towers are designed to handle only a few gallons of water per minute, which is supplied by small pipes. The large towers cool hundreds of thousands of gallons of water per minute. The pipes supplying the water are up to fifteen feet in diameter. These are found in large power plants.&lt;/p&gt;&lt;p&gt;There are several different types of cooling towers. One such type is the mechanical-draft cooling towers. They rely on power driven fans that draw or force the air through the specific tower.&lt;/p&gt;&lt;p&gt;Another type of cooling tower is the natural draft-cooling tower. It uses buoyancy of exhaust air rising in a chimney to provide the needed draft for cooling. Another type is the fan-assisted natural draft tower uses a mechanical draft to expand the buoyancy.&lt;/p&gt;&lt;p&gt;In the past, they relied on the prevailing winds to get the air drafts needed for cooling.&lt;/p&gt;&lt;p&gt;Cooling towers can emit a lot of noise. Things that cause the noise include the sound of water falling, the sound of large fans along with motors and drive belts as well.&lt;/p&gt;&lt;p&gt;Many terms are associated with water coolers. We will briefly go over a few of them. Leaching refers a loss of wood preservative chemicals caused by the washing action of flowing water through a wooden cooling tower. A plume is a stream of exhaust leaving the tower.&lt;/p&gt;&lt;p&gt;Blowouts are water droplets that are blown out of the cooling towers with the exhaust air that is blown out.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;There is more to learn about cooling towers, so please visit our website today&lt;/p&gt;&lt;p&gt;Your guide to everything you have ever wanted to know about a &lt;a id="link_83" target="_new" href="http://www.theheatexchangers.com/Cooling_Towers.html"&gt;cooling towers&lt;/a&gt; and heat exchangers.

The one most people are familiar with is building cooling (HVAC systems), but many important industrial processes also require cooling towers such as electrical power generation.&lt;/p&gt;&lt;p&gt;Cooling towers use the principle of evaporative cooling to reduce the temperature of water. The human body uses the same principle. As we heat up we sweat, as this water evaporates from the surface of our skin we cool down. In a building the air conditioning system uses cooling heat transfer fluid to carry heat from inside the building to the outside. This fluid in turn needs to be cooled so it can return to the building and pick up more heat. Water is used for this purpose. The cooling water is then taken to a cooling tower where it is allowed to evaporate cooling the water so it in turn can lower the temperature of the heat transfer fluid used inside the building.&lt;/p&gt;&lt;p&gt;Since the cooling water is constantly evaporated more water must be added to the tower (make-up water) to maintain the volume. In addition, because the minerals in the water concentrate with evaporation, some water has to be released to reduce the concentration of the minerals (blow down). Since the cooling tower water is warms, oxygenated and constantly exposed to the environment, it is a good medium for the growth of bacteria. Some of these bacteria can be harmful such as the Legionella bacteria that can cause illness in humans. Other bacteria can form surface films (biofilms) on the heat exchange equipment that reduce the efficiency of the cooling system and thus waste energy. Some of the organism can also cause the materials in the cooling system to corrode requiring replacement of expensive equipment. As a result the growth of micro organisms in the cooling water must be controlled.&lt;/p&gt;&lt;p&gt;Ozone generators have been used extensively for the treatment of cooling water. This is due to the fact that ozone is a powerful, but environmentally friendly biocide. Ozone's effectiveness has been studied by the various agencies of US government and shown to be effective. For example, NASA uses ozone to treat cooling water at the Kennedy Space Center where they conduct racket launches.&lt;/p&gt;&lt;p&gt;Ozone is a powerful biocide, which, when compared to conventional chlorine based biocides, not only combats microbial growth processes but also reduces organic impurities often found in the cooling water reducing potential discharge problems with the blow down. In addition, by reducing the concentration of these impurities the amount of water blown down or wasted can also be reduced.&lt;/p&gt;&lt;p&gt;Ozone is produced in an ozone generator and usually injected continuously into the cooling water system in a branch stream. The microorganisms in the systems are thus under permanent attack and micro organism counts are held at a very low level. This also applies to the bio films in the systems, so the tendency for coatings to form is kept to a minimum. This means that intervals between overhauls and maintenance sessions can be extended.&lt;/p&gt;&lt;p&gt;A residual ozone concentration of 0.1 to 0.2 ppm is typically effective in keeping the cooling tower and the cooling circuit clean.&lt;/p&gt;&lt;p&gt;Advantages of ozone generator use in cooling towers include:&lt;/p&gt;&lt;ul&gt;&lt;li&gt;Lower Corrosion Rates&lt;/li&gt;&lt;li&gt;No Toxic Chemicals in Blow Down (ozone breaks down to oxygen).&lt;/li&gt;&lt;li&gt;Lower Overall Chemical Use&lt;/li&gt;&lt;li&gt;Eliminates Storage of Biocides (ozone is produced on site from air)&lt;/li&gt;&lt;li&gt;Effective in a Wide pH Range&lt;/li&gt;&lt;li&gt;Improved Heat Transfer Efficiency&lt;/li&gt;&lt;li&gt;Reduced Water use&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;Ozone use in cooling towers requires consideration of the following factors:&lt;/p&gt;&lt;ul&gt;&lt;li&gt;Make-up Water Quality (Hardness, COD Levels)&lt;/li&gt;&lt;li&gt;Dead Spots in the Circulation System&lt;/li&gt;&lt;li&gt;Water Temperature&lt;/li&gt;&lt;li&gt;Materials of Construction&lt;/li&gt;&lt;/ul&gt;&lt;p&gt;When applied properly and in the proper circumstances ozone can improve the operation of cooling towers while saving money and protecting the environment.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;Anthony Sacco is a director of Spartan Environmental Technologies, LLC.

It is a little bit of a fairy tale when you think that water can be. Water is a universal solvent. When water is given to the environment, it becomes immediately contaminated with many different organic and inorganic substances.&lt;/p&gt;&lt;p&gt;Not every one of the contaminants is bad for you. Some of them can be toxic for humans to consume. The water treatment systems are designed and necessary for removing these substances from your water and giving you clean and safe water to drink.&lt;/p&gt;&lt;p&gt;There are many different water treatment systems to choose from. It will depend on the water that you are trying to get treated. One of the water treatment methods that you may want to try is known as the ozone water treatment method.&lt;/p&gt;&lt;p&gt;&lt;b&gt;What is meant by ozone?&lt;/b&gt;&lt;/p&gt;&lt;p&gt;Ozone or O3 is a gas that has no color or smell to it. The ozone gas will have a reaction with anything that it comes in contact with. Because of this reaction, the ozone is used largely for cleaning and disinfecting things. The ozone gas is so highly reactive that it will cause corrosion on the things that it meets. Ozone is a great way to disinfect and clean but, for living tissue contact, it can be damaging in great ways.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Why Use Ozone Gas To Treat Water?&lt;/b&gt;&lt;/p&gt;&lt;p&gt;It is a very easy answer; ozone is the greatest biocide that is available. It reacts in a big way with the water and this makes it a great thing for water treatment. Ozone gas will kill viruses, bacteria, microorganisms, and fungus in the water. It can also stop scale deposits from forming and causing hard water to occur.&lt;/p&gt;&lt;p&gt;In certain research studies, legionella has also been destroyed by ozone gas. Legionella is a bacterium that is found to thrive in cooling towers. Every test that has been done shows that by sending ozone gas into the cooling tower will lower the bacteria counts and will provide standards for drinking water that is of a better quality. Ozone gas has also been shown to impact corrosion in the heat surfaces in a positive way.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Good Things For Ozone Water Treatment Use&lt;/b&gt;&lt;/p&gt;&lt;p&gt;The main good quality of using an &lt;a id="link_77" target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/GE_reverse_osmosis_water.html"&gt;ozone water treatment system&lt;/a&gt; is that it is able to get rid of the microorganisms that are found in water. Biological films ore one of the worst problems facing today’s supply of fresh water. By getting the biological agents under some sort of control, the ozone water treatment system can make sure that the water is free form viruses, bacteria, and other substances.&lt;/p&gt;&lt;p&gt;The ozone water treatment system will also help to eliminate the problem of scale deposits in the pipes. Because it inhibits the gathering of scale deposits, it will help to improve the work quality of the heat transfer surfaces. This ozone gas will make the system very good for industrial use and especially good for those systems that use water to heat or cool.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;You can also find more info on &lt;a id="link_78" target="_new" href="http://www.ewatertreatmentsystems.com/"&gt;water treatment&lt;/a&gt; and &lt;a id="link_79" target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/Buy_water_treatment_online.html"&gt;extensive water treatment&lt;/a&gt;. eWaterTreatmentSystems.com is a comprehensive resource for water treatment with information on reviews, reverse osmosis and how it works.&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1716469170445491974-1702140146873931205?l=cooling-tower.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cooling-tower.blogspot.com/feeds/1702140146873931205/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1716469170445491974&amp;postID=1702140146873931205' title='1 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/1702140146873931205'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/1702140146873931205'/><link rel='alternate' type='text/html' href='http://cooling-tower.blogspot.com/2008/11/water-treatment-by-using-ozone.html' title='Water Treatment by Using Ozone'/><author><name>alzack</name><uri>http://www.blogger.com/profile/17521948257526887706</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1716469170445491974.post-1381336913063261736</id><published>2008-10-17T09:15:00.000-07:00</published><updated>2008-10-17T09:16:24.711-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Cooling tower parts'/><title type='text'>Cottonwood Air Intake Filter Screens</title><content type='html'>&lt;div id="body"&gt;&lt;p&gt;When you think of chiller and cooling tower maintenance the first thought is usually about how much of a hassle it is to perform this important but unpleasant task; power washers, cleaning solvents hoses, buckets and other cleaning accessories need to be assembled and moved from unit to unit, up and down off of rooftops, behind buildings and other out of the way locations; chillers and cooling towers need to be opened, housings need to be removed and internal components power washed (all the while getting the debris from the cleaning process all over you) then the equipment needs to be reassembled before moving to the next one - WOW, what a hassle!&lt;/p&gt;&lt;p&gt;As unpleasant this job is, ensuring that the cooling equipment which supports your production process stays clean and running efficiently is one of the most mission critical jobs there is because if your process cooling equipment fails due to system fouling, then production will fail - costing the business thousands of dollars in maintenance, repairs, downtime and lost productivity.&lt;/p&gt;&lt;p&gt;In most regions of North America, cottonwood seed is a major contributor of cooling equipment fouling. This naturally occurring airborne contaminant (generated by the Poplar Tree) usually effects operations from May thru early August, hence, companies that rely upon process cooling must clean their equipment frequently during this period or risk failure. Then comes the dog days of summer when insects, paper, construction debris, birds and just about everything that blows in the wind seems to find its way into your cooling equipment, then comes the final seasonal assault during the fall season when the trees drop their leaves, scattering them to the wind where they always seem to find their way to your condenser coils and cooling towers.&lt;/p&gt;&lt;p&gt;Keeping up with HVAC maintenance during the spring, summer and fall is nearly a full time job for most production operations and as the economic realities of business cause maintenance budgets and staffing to be reduced, it is increasingly important that companies find effective maintenance solutions that will streamline their day to day HVAC maintenance activities and enable them to more effectively handle work loads with fewer people and with fewer budget dollars.&lt;/p&gt;&lt;p&gt;Think about it, if you are in a lean maintenance staffing situation and you had five things to do on any given day and one of the tasks was cleaning condenser coils and cooling towers, how high on the "To Do List" would it rank? Given that it's time consuming and hard, dirty work, most people would rank it pretty low; Unfortunately, if the equipment is in need of cleaning and maintenance continues to be delayed, no reason for delaying it will change that fact and the equipment will continue to operate at an increasing level of inefficiency until the equipment can no longer support the cooling requirements.&lt;/p&gt;&lt;p&gt;Now consider the same list of five things to do except this time cleaning cooling towers and chiller coils only took a few minutes per unit using a broom, now where would this task would fall on the "To Do List"? Well, there's no real way of knowing, but the likelihood of it ranking high on the list is pretty good. Furthermore, if cleaning the equipment was as easy as using a broom or rinsing with a garden hose and it didn't require opening or disassembly of the equipment, then nearly anyone could perform the maintenance and that would change the dynamics of the HVAC / Cooling tower maintenance process.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;How to Change the Dynamics of the Maintenance Process.&lt;/strong&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;Air Intake Filtration specifically engineered for use on condenser coils, cooling towers and other HVAC equipment is one of the best ways to prevent fouling of your equipment. Unlike window screen, bug screen, shade screen and conventional filters including roll media, pleated filters and electrostatic filters which are largely designed for internal use on air handling units and forced air heating systems, Air intake filters are specifically designed to mount to the outside of the equipment where it stops airborne debris before it enters your system and where it can be easily seen and quickly removed using a broom, brush, shop vacuum or by simply rinsing with a garden hose - Even the rain has a cleansing effect on air intake filters and they never need to be removed for cleaning. Furthermore, because of the critical airflow requirements on cooling towers, and air cooled chillers, air intake filters are specifically engineered to be nearly invisible to the airflow on high volume / high velocity air flow systems &lt;em&gt;(static pressure drop is less than 1/10" w.g. at 600 fpm air velocity)&lt;/em&gt;.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;So What's The Big Deal About Air Intake Filtration?&lt;/strong&gt; Air Intake Filters help eliminate the "hassle factor" by dramatically reducing HVAC maintenance time and effort - but the benefits don't end there; here's what else they will do to save budget dollars and change the dynamics of your maintenance process:&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Condenser Coil Filter Screens -Benefits&lt;/strong&gt;&lt;/p&gt;&lt;ul&gt;&lt;li&gt;Prevents debris from getting into coils. &lt;/li&gt;&lt;li&gt;Reduces / eliminates annual pressure washing &lt;/li&gt;&lt;li&gt;Reduces / eliminates need for cleaning chemicals &lt;/li&gt;&lt;li&gt;Helps reduce energy cost because coils stay clean all season long. &lt;/li&gt;&lt;li&gt;Dramatically reduces maintenance, repairs, downtime and lost productivity. &lt;/li&gt;&lt;/ul&gt;&lt;strong&gt;Cooling Tower Filter Screens - Benefits&lt;/strong&gt; &lt;ul&gt;&lt;li&gt;Reduces / eliminates sludge build-up in the basin by significantly reducing bio-loading. &lt;/li&gt;&lt;li&gt;Prevents fouling of fill. &lt;/li&gt;&lt;li&gt;Prevents plugging of strainers, blow-down valves and heat exchangers. &lt;/li&gt;&lt;li&gt;Helps reduce algae growth by diffusing sunlight, which supports photosynthesis. &lt;/li&gt;&lt;li&gt;Reduces water treatment chemical consumption due to reduced bio-loading. &lt;/li&gt;&lt;li&gt;Dramatically reduces maintenance and repair cost, downtime and lost productivity. &lt;/li&gt;&lt;/ul&gt;&lt;/div&gt;&lt;p&gt;Air Solution Company developed and patented the first Air Intake Filter specifically engineered to mount to the outside of cooling towers and other HVAC equipment for purposes of stopping the debris before it entered into the system. Since that time, Air Solution Company has been manufacturing and has introduced a variety of other innovative filter systems including its new Fine Mesh Filter which is engineered for use on small and medium size refrigeration coils and machine fan intake housing units.

There are number of evaporative designs that people can purchase.&lt;/p&gt;&lt;p&gt;* Direct Evaporative Coolers - this open circuit is used to lower the temperature of air by using what is referred to as a latent heat of evaporation, changing water into vapour. The energy in the air does not change. During the process the warm dry air is changed to cool moist air.&lt;/p&gt;&lt;p&gt;* Indirect Evaporative Cooling - This is a closed circuit system. It is similar to a direct evaporative cooling system. However in this case some sort of heat exchanger is needed. The cooled moist air never comes in contact with the conditioned environment.&lt;/p&gt;&lt;p&gt;* Two-stage Evaporative Cooling - this system is also referred to as an indirect cooling system. This is a traditional system of cooling that uses only a fraction of energy of vapour compression air condition systems. There are drawbacks to using this system however as they tend to make the air very humid which can make people very uncomfortable.&lt;/p&gt;&lt;p&gt;* Cooling towers - cooling towers are structures that are used for cooling water. This process works in a similar way as the evaporative air cooler system. Cooling towers are typically used on large and tall buildings or in industrial sites. They work as they transfer heat to the environment from chillers, for example in the Rankin power cycle.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;For more information on &lt;a id="link_74" target="_new" href="http://www.homeclimate.biz/"&gt;heating and air conditioning&lt;/a&gt; and other related topics, visit Homeclimate at &lt;a id="link_75" target="_new" href="http://www.homeclimate.biz/"&gt;http://www.homeclimate.biz&lt;/a&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1716469170445491974-6830041129233353136?l=cooling-tower.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cooling-tower.blogspot.com/feeds/6830041129233353136/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1716469170445491974&amp;postID=6830041129233353136' title='1 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/6830041129233353136'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/6830041129233353136'/><link rel='alternate' type='text/html' href='http://cooling-tower.blogspot.com/2008/10/types-of-evaporative-air-coolers.html' title='Types of Evaporative Air Coolers'/><author><name>alzack</name><uri>http://www.blogger.com/profile/17521948257526887706</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1716469170445491974.post-5391391192807288000</id><published>2008-09-28T10:48:00.000-07:00</published><updated>2008-09-28T10:54:25.350-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Cleaning cooling tower'/><title type='text'>Learn How to Prevent and Solving Scale and Scum in Cooling System</title><content type='html'>Having headache with your cooling tower scum and scaling problems.

The water carries bacterial growth in it whether it flows through the faucet or if it is flowing through a cooling tower. If this water is not treated as soon as possible, it can rust and corrode and deposits will form inside the water treatment equipment. This reason makes the cooling tower water treatment system so very important.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Problems From Not Maintaining The Cool Tower&lt;/b&gt;&lt;/p&gt;&lt;p&gt;When you do not keep up the proper maintenance on you cooling tower water system, you will find that many different problems will come up. These problems can include scale formation, corrosion, and biological fouling.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Problems With Scale Formation&lt;/b&gt;&lt;/p&gt;&lt;p&gt;Scale is what is formed when wet solids get clogged in the pipes. This scale is made from heat and cold water that contains a very high mineral content. These deposits will continue to build up over time. If these scale deposits start to form on a heat exchange surface, they will eventually clog the passages and slow the system down. The cooling tower can also be affected by the scale deposits. If the deposits block the flow of the basin or fill in the cooling tower, problems arise.&lt;/p&gt;&lt;p&gt;Choosing to use a cooling tower water treatment system will help to stop the problems of scale deposits. It is a very budget friendly way for you to treat the problems you are having but also to lower the maintenance and the cost of maintenance on the cooling tower system itself. The majority of money that is spent each year is on the removal of the scale deposits from the inside.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Inside Corrosion&lt;/b&gt;&lt;/p&gt;&lt;p&gt;When metal starts to dissolve, you have what is known as corrosion. Oxidation effects break the metal down significantly. The breakdown will cause the system to degrade at a faster rate than normal. The major point being that when the metal starts to break down, the strength of the metal and the thickness off the metal are reduced. The structure of the metal can no longer stand up to the pressure that it was designed for and pits and craters can form in the metal.&lt;/p&gt;&lt;p&gt;A cooling tower system will help to stop the corrosion from happening. The better of the treatments for corrosion is the ozone treatment. There are also other methods that work just as good.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Problems With Biological Fouling&lt;/b&gt;&lt;/p&gt;&lt;p&gt;Problems with biological fouling occur when the water has not been used and left for long periods of time. When the water is left unattended, it has the potential to form bacteria, fungus, algae, and protozoa. The microorganisms will eventually get to large proportions in the water and will cause a biological film to form on the surface of the water. This film is very hard to get rid of. This is what is known as biological fouling.&lt;/p&gt;&lt;p&gt;The biological fouling problems are commonly known to be the worst problem that you can encounter with the cooling tower system. The problems that can occur with biological fouling are low heat transfer, the fill can stop working properly, the water flow can be restricted or blocked, or corrosion can occur from the microorganisms present. It can also result in health problems for the humans that are using it.&lt;/p&gt;&lt;p&gt;The use of a &lt;a id="link_74" target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/Buy_water_treatment_online.html"&gt;cooling tower water&lt;/a&gt; system helps to get rid of this particular problem. When you purchase a good system, it will remove the bacteria, viruses, fungus, and any other organisms that should not be in the water. The cooling system will help the fouling that is a problem with the biological affects in the water to not occur. When these nasty things are removed from the water, it will definitely improve the quality of the water and also the flow of the water through the tower.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;You can also find more information on &lt;a id="link_75" target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/water_filtration_for_drinking_purification.html"&gt;drinking purification&lt;/a&gt; and &lt;a id="link_76" target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/water_treatment_online.html"&gt;water treatment&lt;/a&gt;. eWaterTreatmentSystems.com is a comprehensive resource for water treatment with information on reviews, reverse osmosis and how it works.&lt;/p&gt;&lt;p&gt;&lt;span style="display: inline;"&gt;&lt;span style="font-size: 85%;"&gt;-----------------------------------------------------------------------------------------------------------------&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;a href="http://chem-eng.tradepub.com/c/pubRD.mpl?sr=oc&amp;amp;_t=oc:&amp;amp;pc=wp"&gt;&lt;br /&gt;&lt;img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer;" src="http://3.bp.blogspot.com/_QgQkmyCHz1Q/SJm-Dg4dzXI/AAAAAAAAA_s/-gJOerJo_kc/s200/wpc.gif" alt="" id="BLOGGER_PHOTO_ID_5231421409743195506" border="0" /&gt;&lt;/a&gt;&lt;a href="http://chem-eng.tradepub.com/c/pubRD.mpl?sr=oc&amp;amp;_t=oc:&amp;amp;pc=wp"&gt;&gt;&gt;&gt; FREE &lt;span style="font-weight: bold;"&gt;World Pump Magazine&lt;/span&gt;&lt;/a&gt;!!!&lt;br /&gt;&lt;br /&gt;&lt;a href="http://tinyurl.com/5ccvrp" target="_new"&gt;&lt;span style="color: black;"&gt;Sales Training For Engineers &amp;amp; Techies.&lt;/span&gt;&lt;/a&gt;&lt;a href="http://tinyurl.com/5ccvrp"&gt; &lt;/a&gt;&lt;br /&gt;Manuals On How To Sell Technical Products And Services, Find New Clients Or &lt;a id="KonaLink5" target="_top" class="kLink" style="text-decoration: underline ! important; position: static;" href="http://chem-eng.blogspot.com/#"&gt;&lt;span style="font-weight: 400; position: static; color: rgb(176, 0, 0); font-family: Verdana,Tahoma,Arial,sans-serif;"&gt;&lt;span class="kLink" style="font-weight: 400; position: static; color: rgb(176, 0, 0); font-family: Verdana,Tahoma,Arial,sans-serif;"&gt;Hire&lt;/span&gt;&lt;/span&gt;&lt;/a&gt; An Effective Technical Salesperson.&lt;br /&gt;&lt;br /&gt;&lt;span style="font-size: 100%;"&gt;&lt;span style="font-size: 85%;"&gt;&lt;span style="font-size: 85%;"&gt;Do you like to receive &lt;span style="font-weight: bold;"&gt;FREE Technical and Engineering magazines&lt;/span&gt;?

A target nozzle looks like the image attached. That is a "&lt;span style="font-weight: bold;"&gt;Counterflow Nozzle Orifice&lt;/span&gt;" (sizes available from 1/2" - 1 1/2). A &lt;span style="font-style: italic;"&gt;target nozzles&lt;/span&gt; function is to sprinkle the warm cooling water to increase its surface area (for heat transfer with air) before it goes down from the deck to the water basin. It is usually an injection molded polypropylene unit consisting of two parts—the main body with integral target diffuser and a snap-on insert or orifice cap. A &lt;span style="font-style: italic;"&gt;cooling tower deck &lt;/span&gt;may have up to 200 or more target nozzles.&lt;br /&gt;&lt;br /&gt;All this while I only know this type of &lt;a href="http://chem-eng-net.com"&gt;&lt;span style="font-style: italic;"&gt;target nozzle&lt;/span&gt;&lt;/a&gt;.

The cooling tower need to be protected from biocide, should have the correct pH, the right TDS and so on. I have experienced before a terrible disaster where my cooling tower were contaminated with oil due to a leaking heat exchanger. As a result a combination of heat exchanger isolation, massive blow down and effective chemical treatment is required.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;The following article is about a cooling tower expert from Phoniex explaining the effective cooling tower water treatment.&lt;br /&gt;&lt;/p&gt;&lt;p style="text-align: center;"&gt;**************&lt;br /&gt;&lt;/p&gt;&lt;p&gt;Here in the Phoenix metropolitan area, adverse water conditions require intelligent water treatment strategies to adequately maintain water cooled equipment. Proper management of the characteristics of the &lt;span style="font-style: italic;"&gt;cooling tower sump&lt;/span&gt; water along with maintaining good &lt;span style="font-style: italic;"&gt;tower hygiene&lt;/span&gt; in general accomplishes at least four positive things.&lt;/p&gt;&lt;p&gt;1) It &lt;span style="font-style: italic;"&gt;avoids wasting excess water&lt;/span&gt;.&lt;br /&gt;&lt;br /&gt;2) It&lt;span style="font-style: italic;"&gt; inhibits scale formation&lt;/span&gt;.&lt;br /&gt;&lt;br /&gt;3) It &lt;span style="font-style: italic;"&gt;controls biological growth&lt;/span&gt;.&lt;br /&gt;&lt;br /&gt;4) It &lt;span style="font-style: italic;"&gt;reduces the corrosion rate &lt;/span&gt;of metal parts in the tower.&lt;/p&gt;&lt;p&gt;Let's discuss how a &lt;span style="font-style: italic;"&gt;cooling tower &lt;/span&gt;operates to understand why proper &lt;span style="font-style: italic;"&gt;water treatment&lt;/span&gt; is important.&lt;/p&gt;&lt;p&gt;Most residents in the valley are familiar with an &lt;span style="font-style: italic;"&gt;evaporative cooler&lt;/span&gt;. Water from the &lt;span style="font-style: italic;"&gt;evaporative cooler&lt;/span&gt; sump is circulated by a &lt;span style="font-style: italic;"&gt;pump&lt;/span&gt; over pads in the &lt;span style="font-style: italic;"&gt;evaporative cooler&lt;/span&gt; and outside air is drawn through the pads. As the air is drawn through the wet pads some of the water evaporates and cools the air. The cooler air is then circulated into the space where cooling is desired. In the process of cooling the air, the water being recirculated across the pads is also cooled.&lt;/p&gt;&lt;p&gt;That is exactly the same principle being employed in the&lt;span style="font-style: italic;"&gt; cooling tower&lt;/span&gt;, but on a much grander scale. Rejecting large quantities of heat from a building's mechanical system requires a lot of water to be evaporated. For example, a one hundred ton &lt;span style="font-style: italic;"&gt;water cooled chiller&lt;/span&gt; operating at full capacity for 24 hours would require the evaporation of more than four thousand gallons of water. That brings us to the subject of the characteristics of the make up water. Make up water is the water supply that replaces the water being evaporated in the cooling tower.&lt;/p&gt;&lt;p&gt;Here in the metro area, water conditions vary widely because our water comes from several different wells as well as surface sources. The water quality may change rapidly over a short period of time because different sources are utilized for the water supply. Each well has different water characteristics and they often vary widely from one side of town to the other. Water that comes from surface sources, like the Central Arizona Project will usually have significantly different characteristics than well water. Surface water quality may also be influenced by weather conditions such as drought or increased runoff.&lt;/p&gt;&lt;p&gt;As &lt;span style="font-style: italic;"&gt;water evaporates&lt;/span&gt; in the &lt;span style="font-style: italic;"&gt;cooling tower&lt;/span&gt; all of the non-volatile components stay behind in the &lt;span style="font-style: italic;"&gt;sump of the cooling tower&lt;/span&gt;. There is actually a lot more in water than what we would call hardness (carbonates). There are also &lt;span style="font-style: italic;"&gt;chlorides, suspended dust particles and biological microorganisms&lt;/span&gt;. As more and more water is added to replenish the water that is being evaporated, these dissolved and suspended components in the sump water continue to accumulate. If no measures are taken to control the concentration of these components in the water, the solution eventually increases in concentration to a point where "stuff" starts coming out of solution. This "stuff" ends up getting deposited on the surfaces that the water comes in contact with.&lt;/p&gt;&lt;p&gt;Have you ever seen an&lt;span style="font-style: italic;"&gt; evaporative cooler &lt;/span&gt;where the pads haven't been changed for a long while? I've seen them so encrusted with mineral deposits that the blower could no longer pull air through them. I've also seen them produce a bounty of biological growth in the sump water. That is exactly what will happen in a cooling tower without adequate attention to hygiene and an appropriate water treatment strategy.&lt;/p&gt;&lt;p&gt;When solids that are dissolved in water come out of solution they are deposited first on&lt;span style="font-style: italic;"&gt; heat exchange surfaces &lt;/span&gt;and surfaces where the water is being evaporated. &lt;span style="font-style: italic;"&gt;Heat exchangers, water cooled condensers, drift eliminators, the tube bundle&lt;/span&gt; in closed circuit cooling towers and the fill in open &lt;span style="font-style: italic;"&gt;cooling towers&lt;/span&gt; are a few examples of surfaces where this occurs.&lt;/p&gt;&lt;p&gt;Deposition of &lt;span style="font-style: italic;"&gt;mineral scale, dirt and biological fouling &lt;/span&gt;on any&lt;span style="font-style: italic;"&gt; heat exchange surfaces&lt;/span&gt; can result in reduced &lt;span style="font-style: italic;"&gt;heat transfer, reduced tower efficiency and increased energy costs&lt;/span&gt;. While reducing deposition of these is important with regard to the cooling tower, it is absolutely critical to avoid scaling or fouling in the water cooled condenser. Scaling and fouling in the condenser significantly reduces heat transfer capability and will seriously impact energy costs, performance and reliability.&lt;/p&gt;&lt;p&gt;A two part strategy is usually employed to manage the mineral content of the sump water. Part one is to maintain the sump&lt;span style="font-style: italic;"&gt; water pH &lt;/span&gt;within allowable limits and to feed the correct type and amount of chemicals to help the water keep more of the dissolved solids in solution. Part two is intentionally sending some of the sump water down the drain (blow down). Blow down reduces the highly concentrated mineral content of the sump water by diluting it with the fresh make up water being added to replace the intentionally wasted water.&lt;/p&gt;&lt;p&gt;&lt;span style="font-style: italic;"&gt;Biological growth&lt;/span&gt; can also become a significant health risk depending on the particular organism involved. Allowing mud and biological growth to accumulate in the sump of a cooling tower can accelerate corrosion of the sump and shorten the life cycle of the &lt;span style="font-style: italic;"&gt;cooling tower&lt;/span&gt;. It can also provide a haven for microbes to escape the effects of a &lt;span style="font-style: italic;"&gt;biocide&lt;/span&gt;.&lt;/p&gt;&lt;p&gt;&lt;span style="font-style: italic;"&gt;Proper water treatment strategy&lt;/span&gt; and good &lt;span style="font-style: italic;"&gt;cooling tower hygiene &lt;/span&gt;is not a one size fits all solution. The quality of the make up water will require an adjustment of the type of the &lt;span style="font-style: italic;"&gt;chemicals and biocide &lt;/span&gt;utilized. It may also require changing feed and blow down rates for proper control. In addition, these requirements may be altered by the characteristics of each individual cooling tower installation.&lt;/p&gt;&lt;p&gt;According to Alan Bateman of DB Water Technologies, there are several things a good cooling tower water treatment program should address in order to be effective. They are total dissolved solids (TDS), hardness, pH, chlorides, suspended solids, an appropriate method for biological control and a proper blow down strategy. Each cooling tower manufacturer publishes recommendations for maintaining proper water conditions of the sump water. The advice of a qualified water treatment professional is advised to ensure that each item above is included in your overall strategy for cooling tower water treatment.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;Mark Strahan is a 35 year veteran of the HVAC industry and is currently an account manager with Burt-Burnett, Inc., an HVAC mechanical service and EMS controls contractor.

The hot summer season spells inconvenience and a lot of sweat at work and at home without air conditioning. On the other hand, the coming of winter signifies torment with the unbearably frigid temperatures that come along with it if one is without air conditioning.&lt;/p&gt;&lt;p&gt;Most office buildings and industrial plants in most countries of the world have air conditioning facilities installed to provide good working environment for their work forces. In temperate countries, modern premises are well equipped with sufficient air conditioning systems to cool both workers and products, especially when the temperature is high all year round.&lt;/p&gt;&lt;p&gt;An office air conditioning system can provide full control of temperature, dust, humidity and air distribution unlike most home cooling systems. Basically, an office air conditioner resembles a room air conditioner where a refrigerant passes through a cooling coil and refrigeration occurs in a separate unit. Multi-storey office buildings on the other hand require larger units and use water-cooled condensers since air-cooled condensers are often not available. A separate cooling tower is usually included in water-cooled condensers in order to conserve water. The condenser water in the cooling tower is cooled by evaporation into the outside air. Sometimes offices have different temperature requirements for different sections. In cases where different sections demand varying temperature settings, two air ducts are used. One duct carries cool air while the other duct carries warm air. Upon entering a space, air is then mixed to the desired temperature as indicated by the thermostat setting. Since space is valuable in any office building, all possibilities are exhausted in order to save this. That's why duct systems with significantly much higher air velocity and air pressure compared with those used in home systems are being used specifically for office air conditioning.&lt;/p&gt;&lt;p&gt;Today's modern school buildings have been provided with cooling equipment as well. Some building designs expose the indoor environment to the heat of the sun especially during the summer season. There are many one-storey schools with huge east and west glass walls and a lot of solar exposure through the roof and windows. These types of buildings necessitate the use of air conditioning units for effective teaching and learning, especially during the hot and humid months of summer. Studies show that there is a correlation between the use of air conditioning and the significant decline in absenteeism during the hot summer days. There is also inconclusive evidence that points to the decrease in respiratory ailments where air conditioning is used in offices and schools.&lt;/p&gt;&lt;p&gt;Air conditioning, whether to provide cool air during hot weather or warm air during cold weather, has proven to be one of the most valuable discoveries of our time. It has provided us with comfort and ease in our daily lives. Those who work in offices and teachers and students in schools can concentrate on their respective tasks because of the comfort that air conditioning provides. Can you imagine working in your office without it? You might just freak out!&lt;/p&gt;&lt;/div&gt;&lt;p&gt;Michael Russell&lt;/p&gt;&lt;p&gt;Your Independent guide to &lt;a id="link_83" target="_new" href="http://air-conditioning-guide.com/"&gt;Air Conditioning&lt;/a&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1716469170445491974-8393559561107769223?l=cooling-tower.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cooling-tower.blogspot.com/feeds/8393559561107769223/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1716469170445491974&amp;postID=8393559561107769223' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/8393559561107769223'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/8393559561107769223'/><link rel='alternate' type='text/html' href='http://cooling-tower.blogspot.com/2008/04/air-conditioning-is-it-really-necessary.html' title='Air Conditioning, Is It Really Necessary?'/><author><name>alzack</name><uri>http://www.blogger.com/profile/17521948257526887706</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1716469170445491974.post-1624885948777981949</id><published>2008-04-26T07:22:00.000-07:00</published><updated>2008-04-26T07:24:19.366-07:00</updated><title type='text'>Keeping Cooling Towers and Heat Exchangers Clean</title><content type='html'>&lt;div id="body"&gt;&lt;p&gt;&lt;strong&gt;Filtration Systems Can Reduce Maintenance and Downtime.&lt;/strong&gt;&lt;strong&gt; &lt;/strong&gt;&lt;/p&gt;&lt;p&gt;To strike an interesting analogy, your cooling tower and heat exchanger is what the lungs and heart are to the human body; when either aren't working properly, it effects other parts of the body and your health suffers. Similarly, when your cooling tower and heat exchanger isn't clean, the heat exchange process doesn't work efficiently and the health of your production and process cooling system suffers.&lt;/p&gt;&lt;p&gt;Process cooling systems that rely on cooling towers to dissipate heat from process cooling water accomplish this by drawing massive volumes of air into the cooling tower as the water travels through the fill material on its way back to the basin. Through the natural evaporative process, heat is dissipated from the water before it reaches the water basin from which it is re-circulated through the chiller then through the heat exchanger and back again &lt;em&gt;(kind of like when you sweat while working and letting the air evaporate the perspiration to cool you down)&lt;/em&gt;. It is important to realize that cooling towers are gigantic air scrubbers that capture all airborne debris that happen to be floating nearby, and if your system doesn't have effective filtration, the debris can clog the fill and get circulated and trapped in the heat exchanger where it can build-up, restrict water flow and cause your process equipment to malfunction due to overheating.&lt;/p&gt;&lt;p&gt;An example of this is illustrated by a major automotive assembly facility that had faced periodic downtime due to their robotic welding systems not holding tolerances and causing quality problems. After the robotic technicians spent several days trying to initially solve the problem, one of the maintenance workers opened the heat exchanger and discovered that it was impacted with cottonwood seed, insects and other debris - flow had been reduced and the robotic equipment was running hot. Now you might be asking yourself, whey didn't they have some sort of filtration equipment? The answer is simple; at the time the facility was built, the ambient conditions in that area didn't require a filtration system. However, as the years went by and the area became more developed and cottonwood tree populations grew, the need eventually surfaced.&lt;/p&gt;&lt;p&gt;The interesting thing to note about this situation is that even though cleaning the heat exchanger got the robotic welding system back on-line and running at peak performance, it didn't solve the problem. In fact, cleaning heat exchangers is like taking a cold capsule to relieve the symptoms of a cold. Unless you treat the root cause of the problem, the cooling system will suffer time and again. The root cause in this case and in most heat exchanger fouling situations is the cooling tower - stop the debris from getting into the cooling tower and it will protect the entire process cooling system including fill, cooling water, chiller and heat exchanger. With the proper filtration technology, your process cooling system will stay clean and running efficiently all season long.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Selecting The Right Filtration System&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;It is important to realize that optimizing the ecology and operational efficiency of your evaporative cooling system is best accomplished by combining a chemical treatment regimen with some type of filtration. The reason is that chemical treatment specifically targets suspended solids and particulates of 40 microns and below, while filtration systems are designed to stop larger debris, especially the kind that causes system clogging and fouling.&lt;/p&gt;&lt;p&gt;For cooling tower filtration, there are two general technologies: &lt;em&gt;Water Based Systems&lt;/em&gt; for which there are a few different variations and &lt;em&gt;Air Intake Filtration Systems&lt;/em&gt;. With water-based systems, the choices include basic water strainers that remove debris by simply passing water through a mesh strainer; sand filtration systems that remove debris by passing the water through sand and centrifugal separators that spin the water and remove the debris through centrifugal action. In contrast, Air Intake Filter Systems remove the debris by filtering the air as it is being drawn into the cooling tower, keeping the debris out of the system in the first place. When considering your filtration options, the following questions should be asked.&lt;/p&gt;&lt;ul&gt;&lt;li&gt;What is the cost associated with downtime due to heat exchanger or cooling tower fouling or clogging? (Knowing this will help you justify your filtration system cost) &lt;/li&gt;&lt;li&gt;What type of debris is most problematic (can you see it or is it microscopic)? &lt;/li&gt;&lt;li&gt;Specifically what part of the system does the filter protect? &lt;/li&gt;&lt;li&gt;Which system provides the greatest filtration surface area (this can directly impact frequency of cleaning - the smaller the filter the more frequently it needs cleaning) &lt;/li&gt;&lt;li&gt;Can the system be installed without shutting down the cooling tower? (If the cooling tower must be shut down for installation, you need to factor lost productivity into the cost of your filtration system if it's not being installed during shutdown periods.) &lt;/li&gt;&lt;li&gt;What is the cost associated with both the filter and installation? &lt;/li&gt;&lt;li&gt;How easy is the system to install and maintain? &lt;/li&gt;&lt;/ul&gt;Answering the above questions will help you to fully understand your options and to make the best choice for your operation.&lt;p&gt;In the case of the automotive manufacturer, the solution they selected was the Air Intake Filter system. The reason was that they needed a system that would protect their entire process cooling system including fill material, cooling water, chiller and heat exchanger. When they evaluated water-based systems, they discovered that the options provided varying degrees of protection for the chiller and heat exchanger but didn't protect the cooling tower where the root of their problem was. If they had selected a water-based system, their cooling tower would have still drawn airborne debris into both the fill and water where the water filter would have captured the debris before it circulated throughout the system. From a maintenance standpoint, that would have solved the heat exchanger problem but it would have done little to reduce maintenance on the cooling tower. Further, when they compared the cost of water based filtration versus air intake filtration technologies, Air Intake Filtration was found to be the more cost effective approach for their operation.&lt;/p&gt;&lt;p&gt;If you are not currently using a filtration system as part of your process cooling system, then any filtration technology will give you more protection than you have now, however, selecting a solution best suited to your operation requires that you know what kind of debris is the problem and where it is getting into the system. As a rule of thumb, " don't select a small debris solution to solve a large debris problem". Conversely, "don't select a large debris solution to solve a small debris problem". There is clearly a place for both water based filtration and air intake filtration - be sure you're selecting the right filtration for your specific need.&lt;/p&gt;&lt;p&gt;If you are looking to protect only your chiller and heat exchanger from airborne debris, then one of the water-based filtration technologies in combination with a good water treatment program can help you manage the debris that gets into the cooling water. If on the other hand, you're looking for full process cooling system protection, then you should look at Air Intake Filtration - It will stop the debris from getting into your system in the first place.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;Air Solution Company developed and patented the first Air Intake Filter specifically engineered to mount to the outside of cooling towers and other HVAC equipment for purposes of stopping the debris before it entered into the system. Since that time, Air Solution Company has been manufacturing and has introduced a variety of other innovative filter systems including its new Fine Mesh Filter which is engineered for use on small and medium size refrigeration coils and machine fan intake housing units.

The water carries bacterial growth in it whether it flows through the faucet or if it is flowing through a cooling tower. If this water is not treated as soon as possible, it can rust and corrode and deposits will form inside the water treatment equipment. This reason makes the cooling tower water treatment system so very important.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Problems From Not Maintaining The Cool Tower&lt;/b&gt;&lt;/p&gt;&lt;p&gt;When you do not keep up the proper maintenance on you cooling tower water system, you will find that many different problems will come up. These problems can include scale formation, corrosion, and biological fouling.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Problems With Scale Formation&lt;/b&gt;&lt;/p&gt;&lt;p&gt;Scale is what is formed when wet solids get clogged in the pipes. This scale is made from heat and cold water that contains a very high mineral content. These deposits will continue to build up over time. If these scale deposits start to form on a heat exchange surface, they will eventually clog the passages and slow the system down. The cooling tower can also be affected by the scale deposits. If the deposits block the flow of the basin or fill in the cooling tower, problems arise.&lt;/p&gt;&lt;p&gt;Choosing to use a cooling tower water treatment system will help to stop the problems of scale deposits. It is a very budget friendly way for you to treat the problems you are having but also to lower the maintenance and the cost of maintenance on the cooling tower system itself. The majority of money that is spent each year is on the removal of the scale deposits from the inside.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Inside Corrosion&lt;/b&gt;&lt;/p&gt;&lt;p&gt;When metal starts to dissolve, you have what is known as corrosion. Oxidation effects break the metal down significantly. The breakdown will cause the system to degrade at a faster rate than normal. The major point being that when the metal starts to break down, the strength of the metal and the thickness off the metal are reduced. The structure of the metal can no longer stand up to the pressure that it was designed for and pits and craters can form in the metal.&lt;/p&gt;&lt;p&gt;A cooling tower system will help to stop the corrosion from happening. The better of the treatments for corrosion is the ozone treatment. There are also other methods that work just as good.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Problems With Biological Fouling&lt;/b&gt;&lt;/p&gt;&lt;p&gt;Problems with biological fouling occur when the water has not been used and left for long periods of time. When the water is left unattended, it has the potential to form bacteria, fungus, algae, and protozoa. The microorganisms will eventually get to large proportions in the water and will cause a biological film to form on the surface of the water. This film is very hard to get rid of. This is what is known as biological fouling.&lt;/p&gt;&lt;p&gt;The biological fouling problems are commonly known to be the worst problem that you can encounter with the cooling tower system. The problems that can occur with biological fouling are low heat transfer, the fill can stop working properly, the water flow can be restricted or blocked, or corrosion can occur from the microorganisms present. It can also result in health problems for the humans that are using it.&lt;/p&gt;&lt;p&gt;The use of a &lt;a id="link_83" target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/Buy_water_treatment_online.html"&gt;cooling tower water&lt;/a&gt; system helps to get rid of this particular problem. When you purchase a good system, it will remove the bacteria, viruses, fungus, and any other organisms that should not be in the water. The cooling system will help the fouling that is a problem with the biological affects in the water to not occur. When these nasty things are removed from the water, it will definitely improve the quality of the water and also the flow of the water through the tower.&lt;/p&gt;&lt;/div&gt;&lt;p&gt;You can also find more information on &lt;a id="link_84" target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/water_filtration_for_drinking_purification.html"&gt;drinking purification&lt;/a&gt; and &lt;a id="link_85" target="_new" href="http://www.ewatertreatmentsystems.com/watertreatment/water_treatment_online.html"&gt;water treatment&lt;/a&gt;. eWaterTreatmentSystems.com is a comprehensive resource for water treatment with information on reviews, reverse osmosis and how it works.&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1716469170445491974-8643429991637261053?l=cooling-tower.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://cooling-tower.blogspot.com/feeds/8643429991637261053/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=1716469170445491974&amp;postID=8643429991637261053' title='1 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/8643429991637261053'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1716469170445491974/posts/default/8643429991637261053'/><link rel='alternate' type='text/html' href='http://cooling-tower.blogspot.com/2008/04/important-information-on-cooling-tower.html' title='Important Information On The Cooling Tower Water Treatment'/><author><name>alzack</name><uri>http://www.blogger.com/profile/17521948257526887706</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry></feed>
