For
air line protection, Van Air RD Series refrigerated compressed
air dryers combine the newest technology in heat transfer
with a proven refrigeration system to keep your pneumatic
equipment running at peak efficiency. Providing a constant
35 - 38° F dew point and low initial cost, an RD Series
refrigerated air dryer provides the best combination of performance
and economy.
All
the components of an RD Series refrigerated compressed air
dry are housed in a powder coated cabinet to ensure a long
useful life. All units include CFC-free R-22 refrigerant,
a refrigerant analyzer light, non-cycling refrigerant compressors,
a compressor run light, and a built-in drain.
A capacity
control valve allows the dryer to operate efficiently at
low loads by preventing heat exchanger freeze-ups. The control
valve also keeps the dew point steady when the air flow
changes. For maximum performance, it is recommended that
a pre-filter be installed.
