REFRIGERATED AIR DRYERS QPNC — NON-CYCLING DRYER OPERATION Quincy Non-Cycling dryers use a two-stage heat exchanger system to maintain consistent dew points. Freeze-ups are prevented and optimum performance is maintained by integrating the highest quality components and refrigeration controls into our system. The system reduces the temperature of the compressed air to appox. +39°F forcing entertained moisture to condense. The mixture of condensed liquids and cold air then flow into the cold point moisture separator where the liquids are collected and removed by an electronic No Loss...

QPCD — CYCLING DRYER OPERATION 5 Quincy Cycling Dryers save energy by turning the refrigeration system on and off in response to demand. A three-stage cold air module combined with our exclusive Cold Storage Integration (CSI) chiller provides more cold storage and higher energy savings than conventional cycling designs. Thermostatic controls provide tight dew point control and prevents freeze ups. Contaminated compressed air flows into the 3-in-1 cold air module first stage exchanger section where it is pre-cooled by the cold air returning from the chilled mass section. The pre-cooled...
