Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere.

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.

As mentioned above all the cooling towers are operated in the environment full of steam and water that is why most of the cooling accessories of the cooling tower are made of either good quality wood or of fiber and same is applicable for the cooling fan in cooling towers.
