Closed-circuit cooling systems can cut the operating costs of water-cooled industrial equipment and machinery such as compressors or turbines that require a source of cool, clean water in order to function correctly. Evaporative fluid cooling systems combine an outside evaporative fluid cooler with a pumping station to circulate a glycol solution between the evaporative cooler and the equipment to be cooled. The fluid can be cooled to 5 to 10oF above the prevailing ambient air wet bulb temperature. Features of the evaporative cooler include a galvanized steel tube nest over which a pump continuously sprays water. A water makeup valve maintains the spray water level in the sump.
