Quincy Non-Cycling dryers use a two-stage heat exchanger system to maintain consistent dewpoints. 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 condensate drain. The No Loss drain ensure maximum moisture removal while saving energy. Once liquids have been removed, the cold dry compressed air returns through the cold side of the first stage heat exchanger where it is reheated by the warm incoming air. Pipe sweating is avoided and air volume is increased by reheating. The compressed air is now considered treated and ready for delivery to downstream products.

refrigerated air dryers are manufactured to exact standards in state-of-the-art production facilities, featuring high capacity, balanced com-ponent selection and consistent output.  This, combined with a clean, simple design, creates an efficient, reliable and environmentally friendly non cycling refrigerated air dryer.

Quincy refrigerated air dryers allow plant equip-ment to run efficiently, and processes more reli-ably, by providing the cleanest compressed air utility possible. Payback starts immediately upon start up.
