Airborne dust, sand, pollen, algae, and pipe scales often contaminate the cooling tower water. They circulate through chillers, compressors, and heat exchangers, thus significantly reducing the cooling ability of the system.   Dirt particles in the water contaminate the system when they settle on the warm surfaces. Although in the chemical analysis, calcium and magnesium contaminate the system of less than 2% only, and the rest is due to the dirt that is brought in by the cooling tower. The Calcium and magnesium are also the bonding elements that keep the dirt on the equipment. When this happens, scale formation caused by dirt reduces the heat transfer rate and it increases the water pressure drop through the heat exchanger, condenser and pipes. A study made by Carrier® shoes shows 0.002″ fouling increases the pumping needs of the system by 20%. To fix that issue, FILTRATION is the answer.   Filtration is the simplest and the most convenient way to solve these kinds of problems. WATERGUARDph self-cleaning water filters give the ULTIMATE solution to a dirty water problem. These filters operate solely on line pressure. The self-cleaning process is activated by a pressure differential and done in seconds without interrupting the main flow of the water. The filters are compact in size and are designed to meet a wide range of industrial applications.
