Dry Cooler

In dry cooling, heat transfer is achieved by convection only The working medium to be cooled is passed through an air-water heat exchanger in a closed circuit, allowing the waste heat to be passed vapour-free into the surrounding air in form of sensible heat.

The cooling process does not result in any quantitative or qualitative changes of the working medium to be cooled.High ambient temperatures lower the efficiency of convective heat transfer for physical reasons. Higher system temperatures must therefore be allowed for. Dry coolers are larger, require more floor space and a greater air flow than evaporative coolers.
