Keeping clean towers and heat exchangers
filtration system can reduce maintenance and downtime.
To find interesting analogy, your cooling tower and heat exchangers, which are the lungs and heart to the human body if one does not work properly, suffers from the effects in other parts of your body and your health. Even if your cooling tower and heat exchanger is clean, the heat exchange process can not work effectively health and your production process and coolingSystem suffers.
pool cooling process, which are dependent on cooling towers to dissipate heat in order to achieve this cooling process of large amounts of air into the cooling tower, as movements in water are on the way back through. The natural evaporation, heat is lost from the water before it reaches the warm pool where you loop through the radiator and thenHeat exchanger and back (like when you sweat during exercise, and allow air to evaporate the sweat to cool down). It 'important to recognize that the cooling towers, air scrubbers giants to capture all pollutants that float in the air in the immediate vicinity has happened and if your system is not effective filters to block the filling and the movement and dirt trapped in the heat exchanger, where they build, limiting the flow of water and bring to your Process Equipmentto temperature error.
An example is a large car assembly plant that regular downtime before their robotic welding systems have tolerances and cause problems as shown. After the robot technician for several days trying to solve this problem and opened a maintenance staff of the heat exchanger, and found that with poplar seeds, insects and other contaminants have been affected – and the flow was Reducedrobotic devices running hot. Now we wonder whey have a type of filtration? The answer is simple, built at the time the plant was not impose local environmental conditions, a filtering system. But as the years passed and the area was further developed and poplars population growth must eventually showed up.
The interesting thing to note in this situation is that while cleaning the heat exchanger isrobotic welding system back online and optimally, does not solve the problem. Actually, cleaning the heat exchanger as a cold capsule to relieve the symptoms of a cold. If you do not treat the cause of the problem, the cooling system suffers again and again. The reason in this case and in most situations, heat exchanger fouling is cooling tower – stop debris from the cooling tower and the whole process to protect the cooling systemincluding filling, the water-cooled chillers and heat exchangers. With proper filtration, cooling system is clean and efficient process for the whole season is long.
The correct choice of the filtering system
It 'important to recognize that the optimization of the ecology and economy of your evaporative cooling system is the best by a combination of chemical treatment system with some form of filtering. The reason for this is thatchemical treatment, especially for particles and particles of 40 microns or less, while filtering systems to stop larger debris, especially the kind that causes constipation and anti-fouling systems.
For the filtration of cooling tower, there are two general technologies: aqueous systems for which there are several variations of a few air vents and filtration systems. With water systems, means that key decisions filters remove waterDebris by passing the water through a sieve, filtration systems to remove residual sand sand and water through centrifugal separators that spin the water and remove dirt by centrifugal force. Contrary to eliminate intake system air filter, filtering the air remains as it is drawn into the cooling tower, keeps dirt out of the system at first. Since the filter options, the following questionsshould be invited.
What is the cost of downtime due to heating or cooling tower heat exchanger fouling or constipation? (Such knowledge will help to explain the filter cost)
What kind of dirt is more problematic (you can see or microscopic)?
In particular, what part of the system, the filter is protected?
system that provides the largest filtration area (which can directly affect the frequency of cleaning – has reduced the filter more often requiresCleaning)
Can the system without closing the cooling tower will be installed? (If the cooling tower will be closed for installation, you must price factor productivity loss of filtration system is not installed during the downtime.)
What are the costs for both the filter and the associated installation?
As is easy to install and maintain?
Answering these questions will help you understand your full potential and the best place forYour business.
In the case of car manufacturers, the solution is selected, the intake air filter system. The reason was that they needed a material system that would protect the whole process including filling the cooling system, water-cooled chillers and heat exchangers. When water systems assessed, they found that the heat exchanger options of varying degrees of protection for cooling and heating, but do not protectCooling Tower, where the root of his problem was. If they chose a system based cooling tower water would withdraw its rubble to fill in both calm water and where water is filtered debris would take before spreading throughout the system. From a maintenance point of view of the heat exchanger problem solved, but it would be too little to reduce maintenance of the cooling tower would. Also, if you compare the cost ofWater-based filtering technology against the intake air filtration, filtration of the intake was established operation, the cost approach her.
If you do not currently have a filter system as part of your process cooling system, so that any filtration technique gives you more protection, but the choice of a solution best suited to your business than you have now, it is necessary you know what type of problem and debris as the firstSystem. As a general rule is that you do not choose to resolve a small solution of gravel on the ground a big problem. "On the contrary, the choice to terminate a huge stone solution remains small. It 'clearly a place-based water filtration and air filtration – be sure to choose the right filter for your specific needs.
If you only want to protect the radiator and heat exchanger from the air, dirt, so to water-filtrationTechnologies, combined with a good water treatment program can help you, waste, water cooling. While the other hand, are you looking for the complete process cooling systems, so you should look at the air intake filter – This is to stop the debris from your system in the first.
