Water-cooled, reciprocating compressors utilize cooling tower or city water supplies to provide the cooling media to remove the BTU heat from the valve and cylinder jackets. The gallons per minute (GPM) of water flow is dependent on the brake horsepower, the water temperature rise and a factor of 42.5. The factor is an expression of BTU/BHP per minute, derived from the sum of the individual components (cylinders, intercooler, and after cooler) heat rejection.


Water Cooled Recips were the dominant form of air compressing for the first half of the 1900’s, up until the introduction of rotary compressors around 1965. The water-cooled reciprocating compressor remains today the most energy efficient method of compressing air.
