A nano VDR variable speed refrigerated compressed air dryer

Refrigerated Compressed Air Dryers

Variable Speed Dryers

Upgrade your compressed air drying system to the advanced nano VDR variable speed refrigerated compressed air dryer. This cutting-edge technology uses a refrigerant circuit and heat exchangers to efficiently cool compressed air and condense moisture from the air. With the ability to achieve a low-pressure dew point (PDP) of +37.4°F and consume no compressed air during the process, the nano VDR is the ultimate solution for your compressed air needs. Unlike direct expansion dryers that 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. Choose the nano VDR for an upgraded and efficient compressed air drying system.
