Perma Pure HD-Series User Manual

The HD-Series Heatless Dryers consist of two

PRINCIPLE OF OPERATION

chambers filled with highly adsorbent desiccant.
The standard desiccant is molecular sieve 4A.
One chamber dries the gas stream while the
opposite chamber is regenerated. The purging
air is a small portion of dried air taken from the
drying chamber, expanded to atmospheric
pressure and flowed countercurrent through the
regenerating (wet) chamber. Wet purge air is
released from an exhaust port in the vapor state
so that no drain is required. Purge air volume is
controlled with an orifice housed within the unit.

INSTALLATIONHEATLESS DRYER SPECIFICATIONS

1. Connect 110VAC /60Hz or 220VAC/ 50Hz to
Heatless Dryer.

2. Connect compressed air line with minimum
of 60 psig and maximum of 100 psig to ¼”
Compressed Air Inlet port (Refer to Figure 1).

Coalescing oil/water pre-filter is recom­mended for installations where oil or water
mist is present.

3. Purge Air Exhaust ports should be left open
to atmosphere to provide venting (can pipe to
remote location if desired). An inexpensive
particulate after-filter may be used on purge
air exhaust to reduce noise.

4. A 1/4” tubing should be used for connection
to 1/4” Dry Air Outlet fitting. If length of tubing
exceeds 15 meters, 3/8” tubing should be
used.

PERFORMANCE

HD-Series Heatless Dryers will operate
indefinitely once electrical power and air
pressure are supplied. The number one cause
of failure to dry is compressor oil contamination
of the drying media.
