After-cooler
Why After-cooler?
The compressed air from air compressor is provided at temperature higher than ambient temperature by nearly 15℃ due to the heat produced during compression. Such hot and humid compressed air increases load on a refrigerated or desiccant air dryer, reducing dehumidifying performances by increasing load on dehumidifying systems such as a refrigerated/desiccant air dryer.
An after-cooler is an auxiliary system designed to enhance dehumidifying performances by lowering load on a refrigerated or desiccant dryer by cooling high-temperature compressed air and discharging condensate.

Water-cooled After-cooler
A water-cooled after-cooler is a system designed to cool high-temperature compressed air from an air compressor, using cooling water.
Condensate produced when hot compressed air is cooled is drained out through a water separator in the outlet of the water-cooled after-cooler.

Air-cooled After-cooler
An air-cooled after-cooler is a system designed to cool high-temperature compressed air from an air compressor, using ambient air. Condensate produced when compressed air is cooled is discharged through a drain valve in the outlet.
