Air-Cooled AfterCoolers

Donaldson Air-Cooled AfterCoolers (130-4,500 scfm) provide economical cooling by using ambient air to cool the hot compressed air from an air compressor.

Discharge air from an air compressor is generally 180˚F - 350˚F, depending on the type of compressor. As the compressed air cools, about 60% of the water vapor present condenses into liquid water which should be immediately removed from the system with a separator.

Air-Cooled AfterCoolers can be sized to cool the hot compressed air to within 5˚F to 20˚F of the ambient air temperature. Aftercoolers can be installed so normal wasted heat can be reclaimed and recirculated.
