Liquid water in the inlet air will adversely affect the performance of the 500 cfm refrigerated air dryer. Install the dryer downstream of an aftercooler or separator so that the temperature of the 500 cfm refrigerated air dryer inlet air does not exceed 120°F and the inlet air does not contain any liquid water.

If the compressed airflow is relatively constant and does not exceed the dryer flow rating, it is recommended that the 500 cfm refrigerated air dryer be located downstream of the receiver tank. If the nature of the application is such that the air demand regularly exceeds the dryer flow rating, it is recommended that the 500 cfm refrigerated air dryer be located upstream of the receiver.
For safety and convenience, install inlet and outlet shutoff valves and depressurization valves. These valves allow the 500 cfm refrigerated air dryer to be isolated and depressurized for servicing. Bypass piping may be installed around the 500 cfm refrigerated air dryer for uninterrupted airflow when the dryer is serviced. If the compressed air operation cannot tolerate undried air for short periods, install a second dryer in the bypass line.

Compressed air systems commonly require filters to remove compressor oils, particulates, condensed liquids and other contaminants. When an oil-removal filter is used, it should be installed downstream of the refrigerated dryer. At this location, the life of the replaceable filter element is prolonged since some of the entrained oil is removed by the 500 cfm refrigerated air dryer and drained through the separator.
