The GRF Series air dryer takes hot saturated compressed air and cools it in a two stage process. The first stage is an Air-Air heat exchanger where the compressed air is cooled by air discharged from the stage two Air-Refrigeration exchanger. The next stage of cooling is accomplished in the Air-Refrigerant heat exchanger where the refrigeration system cools the process gas to a specified Dewpoint. The moisture condensed from the drop in temperature is separated and removed from the system. The cold and dry air is then becomes the cooling medium for the first stage as well as reheated prior to discharge from the dryer.

The refrigeration system is comprised of a compressor that boosts the refrigeration gas pressure. As the pressure is boosted the temperature is increased through heat of compression. The heat is removed and the Freon gas is condensed to a liquid by an air or water cooled heat exchanger. The high pressure liquid is collected in a receiver then feed to the expansion valve where it is expanded at a regulated volume. The expansion of the liquid causes the Freon to cool which is the equal and opposite reaction to the heat generated by compression. The cold Freon adsorbs the heat of the compressed air stream and evaporates to a gas. Any residual liquid is collected and evaporated in a suction accumulator prior to reentering the compressor before the process repeats.
