Piston Water-cooled Air Compressor
Advantages
Lower Discharge Temperatures: Cooler compression reduces the potential for oil carryover and thermal degradation of lubricants, resulting in cleaner compressed air. Reduced Condensation: Stable temperatures and effective intercooling promote moisture separation, reducing the load on downstream dryers and filters. Consistent Dew Point: Stable operating temperatures mean consistent discharge conditions, simplifying downstream air treatment sizing and operation.
