Closed Circuit Cooling Tower

(also known as an evaporative air cooler or closed cooling tower) is the tubular heat exchanger placed in the tower, through the circulation of air, spray water and circulating water heat exchange to ensure the cooling effect.

The closed circuit cooling tower works as follows

On the secondary side of the cooling tower, the water is sucked out of the pool by a pump and circulated through a stainless steel plate heat exchanger. The water leaving the exchanger is piped to the top of the unit. This water is graded and evenly dispersed over the exchange surfaces by dispersers (also known as water distribution nozzles). Air driven by fans (axial or centrifugal) enters from the lower part of the cooling tower, is heated and saturated with water and exits from the upper part, passing between the exchange surfaces.
