4.1 Dehydrator
The patented drying system begins at the
compressor,wherelteredambientairis
compressed. The compressed air is then cooled
and condensed in the heat exchanger after
which water droplets are separated in the water

This patented drying process contains no
moving parts, thus reducing maintenance and
increasing reliability.
4.2 Dehydrator Control
The ultra-dry air exits the dehydrator at the top
of the unit. Low pressure, High Humidity, and
Excess Run alarms are tapped into the air line
within the dehydrator.
