Closed Circuit Cooling Towers
Depending on the duty required Tektower can provide a Closed Circuit Cooling Tower or solution in any of our EWK, FGS or FM ranges.
The fluid to be cooled (or gas to be condensed) flows through the tubes of a serpentine tube type heat exchanger (the closed circuit) without coming into contact with the external air stream thereby preventing dirt or pollution from entering the system. Heat is transferred from the fluid (or gas) through the tube walls to the cooling water which is sprayed continuously over the coil.
An axial or radial fan drives air through the cooler thereby evaporating some of the cooling water and in so doing releases the required heat int the atmosphere. The remainder of the cooling water is recirculated by means of a spray pump from the cooling tower basin to the spray nozzles.
