Refrigerated air dryers remove water vapor and contaminants carried in the compressed air. Compressed air can contain dirt and oil, which may damage tools and machinery. Our refrigerated air dryer system works to produce clean, dry air. Making this Gardner Denver’s most common type of compressed air dryer.As air enters the refrigerator and through the air-to-air heat exchanger, the outgoing cold air cools the warm air. Then water droplets separate from the cold air, removing the moisture, dirt and oil. The air passes back to the air-to-air heat exchanger, reheating the cooled air exiting the air dryer.Our refrigerated air dryers are separated into two types of air dryers, cycling and non cycling. When purchasing an air dryer it is important to consider the cost. Non-cycling is the most cost-efficient upfront but cycling dryers save energy cost in the long run.
Cycling refrigerated dryers use a controlled heat sink to cool the compressed air. The cycling dryers cycle the refrigeration on and off conserving energy and preventing excessive refrigeration. This air dryer provides very low operating costs because it does not waste energy through continuous operation. This is the best option for operations that use the dryer on an as needed basis.
A non-cycling refrigerated dryer has air continuously circulating to account for the high or low moisture density. The machine will quickly change in response to the incoming air. The non-cycling dryer ensures a constant dew point at all load levels and delivers continuous dry-air performance. Non-cycling dryers are less expensive than cycling dryers because the non-cycling dryers are constantly running at full capacity.
