Keeping Cooling Towers and Heat Exchangers Clean

The systems of filtration can reduce the maintenance and the downtime. To run up against an interesting analogy, your turn of cooling and exchanger of heat are what are the lungs and the heart with the human body; when one or the other does not function correctly, it carries out other parts of the body and your health suffers. In the same way, when your turn of cooling and exchanger of heat is not clean, the process of heat exchange does not function effectively and the health of your production and system of cooling of process suffers. The systems of cooling of processes which are based on lathes of cooling to absorb the heat of cooling water of process achieve this by drawing the massive volumes of air in the tower of cooling while water travels by the fill material on its way again to the basin. By the normal evaporative process, heat is absorbed water before it reaches the basin of the water of which it is recycled by the refrigerator then by the exchanger of heat and th! e back still (kind as when you sweated while working and to let the air evaporate perspiration to kill you). It is important to realize that that the turns of cooling are colossal purifiers of air which capture all the airborne remains which precisely prove to float near, and if your system does not have effective filtration, the remains can block sufficiency and obtain circulated and imprisoned in the exchanger of heat where they can preparing, to limit the flow of water and to cause your equipment of process to the malfunction due to overheating. An example of this is illustrated by a service of the important motor vehicles of assembly which had faced the periodic downtime due to their robot-like systems of welding not holding of the tolerances and not posing problems of quality. After the robot-like technicians spent several days trying to solve at the beginning the problem, one of the workmen of maintenance opened the exchanger of heat and discovered that it was carried! out with seed of poplar, the insects and other remains - the ! flow had been reduced and the robot-like equipment was to run hot. Now you could wonder that, milk they did not have a certain kind of equipment of filtration? The answer is simple; when the service was established, the environmental conditions of the fact the sector did not require a system of filtration. However, while the years were passed and the sector became more developed and populations of tree of poplar developed, the need has glossy thereafter. The thing interesting to note about this situation is that though the cleaning of the exchanger of heat obtained the robot-like back of system of welding on line and operation with the maximum execution, it did not solve the problem. In fact, cleaning exchangers of heat is like taking a cold capsule to relieve the symptoms of a cold. Unless you treat the cause of root of the problem, the system of cooling will suffer many and many times. The cause of root in this case and the majority of clogging exchanger of heat of the situations ! is the tower of cooling - to stop the remains entering the tower of cooling and it will protect the system from cooling of whole process including/understanding sufficiency, cooling water, the refrigerator and the exchanger of heat. With the suitable technology of filtration, your system of cooling of process will remain clean and operation effectively all season a long time. The choice of the good SystemIt filtration is important to realize that that the linearization of the ecology and the operational effectiveness of your system of evaporation cooling better is accomplished by combining a chemical mode of treatment with a certain type of filtration. The reason is that the chemical treatment specifically aims the solids and the particulate substances suspended of 40 microns and below, whereas systems of filtration are conceived to stop larger remains, particularly the kind which causes the system blocking and clogging. For the filtration of turn of cooling, there are two ! general technologies: Systems containing water for which there! are som e different variations and systems from filtration of air intake. With the systems containing water, the choices include the basic sieves of water which remove remains while simply passing water by a sieve of mesh; to sandpaper the systems of filtration which remove remains while passing water by sand and the separators centrifugal which turn water and remove the remains by the centrifugal action. On the other hand, systems of filter of air intake E nlèvent les débris en filtrant l'air pendant qu'il est dessiné dans la tour de refroidissement, gardant les débris hors du système en premier lieu. Quand vu vos options de filtration, on devrait poser les questions suivantes. Queest-ce que le coût lié au temps d'arrêt dû à l'échangeur de chaleur ou à la tour de refroidissement encrasse ou obstrue ? (Savoir ceci vous aidera à justifier votre système de filtration coûté) quel type de débris est le plus problématique est-ce que (vous pouvez êtes le voir ou lui microscopique) ? Spéci! fiquement quelle partie du système le filtre protège-t-il ? Quel système fournit la plus grande filtration la superficie que est-ce que (ceci peut directement effectuer la fréquence du nettoyage - plus est petit le filtre plus a-t-il besoin nettoyer plus fréquemment) peut le système être installé sans arrêter la tour de refroidissement ? (Si la tour de refroidissement doit être arrêtée pour l'installation, avez-vous besoin de productivité perdue par facteur dans le coût de votre système de filtration s'il n'est pas installé pendant des périodes d'arrêt.) ce qui est le coût lié au filtre et à l'installation ? Combien facile est le système à installer et maintenir ? Answering the above questions will help you to fully understand your options and to make the best choice for your operation.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 cool! ing system including fill material, cooling water, chiller and! heat ex changer. 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.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, howeve! r, 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.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.Air Solution Company developed and patented t! he first Air Intake Filter specifically engineered to mount to! the out side 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.
