High Temperature Refrigerated Air Dryers
General Information
Quincy Models QPHT 25, 50, 75, 100 and
125 High Temperature Refrigerated Dryers
are designed to cool and remove moisture
from compressed air. The units cool air
in two stages. Compressed air enters the
system at a maximum temperature of
180°F and is cooled in an aftercooler by
ambient air. It is further cooled in an air to
refrigerant heat exchanger to about 40°F.
Once cooled, the air is sent through an
automatic draining moisture separator and
finally through an optional oil filter.
When properly installed, the units require
little maintenance or adjustment. A list
of service parts is provided in the Parts
List and Drawings book (9829 2101 99).
Contact Quincy or your Quincy distributor
for repair or replacement of other parts on
these units.
