RDP series – Refrigeration Compressed Air Dryer

RDP refrigeration dryers have been designed to effectively separate water from the compressed air thus lower pressure dew point all the way down to +3°C.


Drying is achieved on the principle of cooling which takes place inside highly efficient and ultra-compact 3 stage heat exchanger. In the first stage (air-air heat exchanger) hot and humid inlet air is being precooled by the cold outgoing air. In the second stage (air-refrigerant heat exchanger) intensive water condensation takes place due to cooling the air. All condensed water is separated from the main compressed air stream in the third stage by the integrated demister. A proven and robust design of refrigeration dryers enables efficient and reliable operation, fast installation and simple maintenance.
