Collection: Quincy Air Dryers

A refrigerated dryer gets you to a pressure dew point of about 35 to 40 degrees F. Hold onto that number, because it decides whether this page has what you need.

Quincy rates its refrigerated dryers at the industry standard of 100 degrees F inlet air, 100 PSIG line pressure and 100 degrees F ambient. Real shops rarely hit all three. Air coming off a hot compressor in an unventilated corner can arrive at 110 or 120 degrees F, and a refrigerated dryer loses capacity quickly above its rating, which is why the published CFM is a ceiling rather than a promise. Size to your worst August conditions, not to the nameplate on the compressor.

When a refrigerated dryer is the wrong tool

Nothing on this page will take you below freezing. If a line runs outdoors, through an unheated warehouse, or into a process that specifies a dew point under 32 degrees F, a refrigerated dryer cannot do it at any size or any price. That job belongs to a desiccant dryer, which reaches minus 40 degrees F and costs more to buy and more to run. Our side by side comparison lays out the trade honestly.

The usual failure is a dryer sized to the compressor nameplate and installed in a hot room. Summer arrives, inlet temperature climbs, and water shows up at the tools and in the paint. If you are not certain what dew point your process actually needs, start with what dew point means, then compare the rest of the refrigerated dryer lineup.
