Common applications include cooling the circulating water used in oil refineries, chemical plants, power plants, petrochemical plants, natural gas plant, processing plants, food processing plants, semi-conductor plants, building cooling, and other industrial facilities.The fans mainly used in cooling towers are operate in full of corrosive environment, therefore its performance reduces over a period of time due to corrosion on the fan's surface. The efficiency of cooling tower fan reduces significantly which lead to several cooling problems like improper cooling, non-maintenance of water temperature, proper cooling but with higher power consumption.
