A nano VDR variable speed refrigerated compressed air dryer

Refrigerated Compressed Air Dryers

Variable Speed Dryers

The nano VDR variable speed refrigerated compressed air dryers use a refrigerant circuit and heat exchangers to cool compressed air so that it condenses the moisture in the air. They can provide a pressure dew point (PDP) as low as +37.4°F/3°C and consume no compressed air in the process. Unlike direct expansion dryers which run continuously at full speed, the nano VDR variable speed refrigeration compressors only run at the speed required to dry your process air to the dew point set point of the dryer.
