RDT - Refrigeration compressed air dryers

RDT 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. The main difference between RDP and RDT series is that RDT has timer controlled drain instead of an automatic drain. Drying is achieved on the principle of cooling which takes place inside a highly efficient and ultra-compact 3 stage heat exchanger. In the first stage (air-air heat exchanger) hot and humid inlet air is being pre-cooled by the cold outgoing air. In the second stage (air-refrigerant heat exchanger) intensive water condensation takes place due to the cooling of 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 enables efficient and reliable operation, fast installation and simple maintenance.
