Cooling towers are devices that remove heat and they are also used for transferring waste heat in the atmosphere. Cooling towers are mostly used in industries and factories where production requires disposing of heat. These cooling towers are available in different kinds. The industries would install and construct the specific type of cooling tower that they require. Cooling towers can use two methods of processing waste heat. These two methods include wet bulb air temperature and dry bulb air temperature. The method of evaporation is used to dissipate waste heat and cool down the working fluid to make it come near the wet bulb air temperature. For the dry bulb air temperature it requires closed circuit cooling.
Industrial cooling tower are also used for removing industrial waste heat. Industrial cooling towers are especially used in power plants and petrochemical plants. Apart from these industrial cooling towers are also used on refineries of petrochemical products, natural gas processing plants, semi conductor plants and food processing plants. These cooling towers can also be used for industrial equipments like condensers in a distillation column or for cooling the liquid in crystallization.
