Compressor air dryer refrigeration means that compressed air is cooled to allow for a large amount of water to condense and become separated. After cooling and condensing, compressed air is reheated to around room temperature, so condensation does not form on the outside of the pipe system.

This heat exchange between ingoing and outgoing compressed air also reduces the temperature of the incoming compressed air. Therefore, compressor air dryer refrigeration reduces the required cooling capacity of the refrigerant circuit. Cooling the compressed air takes place via a closed refrigerated system.

Smart steering of the compressor air dryer refrigeration via intelligent control algorithms can significantly reduce the power consumption of modern refrigerated dryers. Compressor air dryer refrigeration are used for dew points between +2 ˚C to +10 ˚C.

In addition, a compressor air dryer refrigeration has a low freezing limit at the point of the condensed water. They are available as either a freestanding machine or an integrated drying module inside the compressor. The latter has the advantage of having a small footprint and ensures optimized performance for the particular air compressor capacity.
