MODEL TCK
Induced draft closed type cooling tower
The operation of the closed type cooling tower is similar to the open system. In the closed type, the heat exchanger coil within the tower separates the hot working fluid from the cooling tower water. During operation cooling tower water is pumped from the basin up to a spray header where it is then sprayed onto a coil containing the heat load from the factory, thereby cooling it down (see Fig. 1). Since the hot fluid is contained in the coil, it is not exposed to the atmosphere and not subject to fouling caused by oxygen and dirt.
