QHD Heatless Desiccant Dryer

Quincy QHD heatless desiccant dryers use a small portion of
dried, compressed air to purge and regenerate the off-line tower. The QHD has
been engineered to ensure optimal performance and efficiency in a range of
different applications while keeping downtime to a minimum.


The QHD series of desiccant dryer systems includes 13 models
that deliver between 230 and 3,400 CFM of clean, dry air at a pressure of 100 psig.
All feature a heavy-duty steel base and dual tower configuration that
regenerates automatically.


Under normal operation, air is forced upwards through the
drying tower, where moisture and contaminants are removed and a small amount ƒ??
15% ƒ?? of air is diverted downwards through the regeneration tower where it
depressurizes the desiccant bed to ambient conditions. Overall velocities are
kept below 50 feet/minute so that air remains in contact with the desiccant for
a minimum of 4.5 seconds. The entire process follows a 6-10 minute NEMA cycle,
which consists of three to five minutes of drying time, 2 minutes and 25
seconds to 4 minutes and 20 seconds of regeneration and 40 seconds of


Like all our desiccant-type air dryers, the QHD heatless air
dryer system includes high-quality components and is backed by a two-year
comprehensive warranty. For details, download the product brochure or contact a
