GREAT LAKES AIR REFRIGERATION DRYERS BY WILLING SERVICE CORPORATION
ERF SERIES AIR DRYER OPERATION
ERF Series Air Dryers will take hot saturated compressed air into an air cooled heat exchanger, where it will cool the air and then a water separator removes condensed liquid. The air will then enter the air exchanger where it is precooled by air that is discharged by the air refrigeration exchanger. The final cooling is done in the air refrigerant exchanger where it is cooled more to the specific dew-point and additional moisture is separated from the air stream. The dry air will enter the air-air exchanger where it will act as a cooling point for the precooling stage. It will also reheat the discharged air to help prevent compressed air piping from sweating and increases the volume.
