Compressed air contains naturally occurring moisture, which can negatively affect applications that require moisture-free air. Refrigerated air dryer ingersoll rand are a common solution for removing moisture content. One of the most popular options is the refrigerated air dryer ingersoll rand because of its ability to reach an acceptable dew point in general industrial plant air applications.

Refrigerated air dryer ingersoll rand operate with a similar principle to domestic refrigerators or home air conditioning systems. The compressed air is cooled in an air-to-refrigerant heat exchanger to about 35°F, a temperature where the moisture condenses and is drained off. An air-to-air heat exchanger is used to both pre-cool the incoming air, and re-heat the outgoing air as it leaves the refrigerated air dryer ingersoll rand. The compressed air leaving the refrigerated air dryer ingersoll rand has a pressure dew point of 35 to 50°F.
