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.
AOSUA           not only provides different shapes of cooling towers used in industries, such as round shape cooling towers and square cooling towers, but also offers closed cooling towers and open circuit cooling towers as well. The type of closed circuit cooling tower is widely used in iron and steel metallurgy, power electronics, machining, air conditioning system and other industries.
Closed Circuit Cooler vs Cooling Tower          
The cooling towers is a specialized heat exchanger where air and water are brought into direct contact with each other in order to reduce the water temperature. The closed circuit cooler is one type of cooling towers , which keeps the system clean and contaminant-free in a closed loop. During operation, heat is transferred from the warm fluid in the coil to the spray water, and then to the atmosphere as a portion of the water evaporates.     
 
Advantages of Closed Circuit Cooling Tower
a.The closed loop cooling tower is a counter flow and cross flow cooling tower based on the design idea of forced circulation. The closed counter flow cooling tower has a closed loop system and covers a small area, has a compact structure, and can be combined with many sets, so the cooling effect is better              .         
 
b. The closed counter flow cooling tower belongs to mechanical refrigeration, which avoids a series of problems that the thermal cycle of the open cooling tower is directly connected with the atmosphere, and the circulating medium is easy to be polluted; the closed counter flow cooling tower uses cold water to cool the medium in the coil directly so that the cooling medium has no pollution, less damage, remarkable energy saving effect and good environmental protection effect.     
c. The wind tube of closed counter flow cooling tower adopts an aerodynamic design. This kind of curve structure greatly reduces the water drift rate of the closed loop evaporative cooler.     
d. The closed counter flow cooling tower adopts coil type structure, and the copper tube or stainless steel tube has a more sufficient heating surface and higher heat exchange efficiency.
