Closed cooling tower is the tube heat exchanger placed in the tower

Brief introduction
Closed Cooling tower (also known as Evaporative air cooler orClosed Cooling Tower) is to place the tubular heat exchanger in the tower, through the circulation of air, sprinkler water and circulating water heat exchange to ensure the cooling effect. Because it is a closed cycle, it can ensure that the water quality is not polluted, very good protection of the efficient operation of the main equipment, improve the service life. When the outside temperature is low, you can stop the sprinkler system and play a water-saving effect. With the implementation of national energy saving and emission reduction policies and the increasing scarcity of water resources, closed cooling towers have been widely used in iron and steel metallurgy, power electronics, machining, air conditioning systems and other industries in recent years.
