1. An air drier for an air compressor, said air compressor having an inlet for receiving ambient air and an outlet for discharging compressed air, said air drier comprising;
- a first fin coil for cooling and dehumidifying ambient air, said first coil having an ambient air inlet for receiving ambient air and an ambient air outlet for discharging ambient air;
said first coil having first and second intertwined tube circuits,said first tube circuit comprising means for conveying refrigerated fluid for cooling said ambient air and second tube circuit, said second tube circuit having an inlet and an outlet, said second tube circuit comprising means for receiving compressed air though its inlet, exchanging heat with said first tube circuit and delivering cooled, dehumiidified compressed air through its outlet.

Abstract
A three function air dehumidifier for air compressors acting on both the ambient air and the compressed air while employing only finned heat exchangers for cooling and dehumidifying ambient air and for exchanging heat between compressed air streams and between evaporating refrigerant and compressed air streams.

- 15. A refrigerated compressed air drier comprising a finned coil having a first circuit having an inlet and an outlet and a second circuit having an inlet and an outlet, said first and second circuits being in heat transfer communication within said finned coil, means for supplying a refrigerated fluid to said first circuit inlet, means for supplying a flow of compressed air having a water vapor component to said second circuit inlet, whereby the refrigerated first circuit cools the flow of compressed air traversing said second circuit, thereby causing a portion of the water vapor component to condense to a liquid, and means for preventing a flow of air over or through the fins of said finned coil.
