The ERF Series air dryer takes hot saturated compressed air into an air cooled heat exchanger, which cools the air, and a gross water separator removes the condensed liquid. The air then enters the Air-Air exchanger where it is pre-cooled by the air discharged from the Air-Refrigeration exchanger. The fi nal cooling is accomplished in the Air-Refrigerant exchanger where it is further cooled to the specifi ed dewpoint, and additional condensed moisture is separated from the air stream. The cool dry air enters the Air-Air exchanger where it acts as the cooling medium for the previous pre-cooling stage. It also reheats the discharge air to increase volume and prevent the compressed air piping from sweating.

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.
