What is a refrigerated air dryer?

They cool the compressed air passing through them and keep that air dry down to the dew point of +3°C.

Inlet and outlet filters integrated into the dryer (up to the HRD 210 model) reduce the particle level by 0.01 microns and the oil particle level by 0.01 mg/m³.
