4.1 Dehydrator
The patented drying system begins at the
compressor,wherelteredambientairis
compressed. The compressed air is then cooled
and condensed in the heat exchanger after
which water droplets are separated in the water
lter.Thesaturatedairthenpassesthrough
acoalescinglterfortheremovalofadditional
water and then into the patented membrane
cartridge where the remaining water is removed
by pressure differential.
Thewaterseparatedintheltersisblown
to a pan on the head of the compressor and
is evaporated by the heat of compression.
Theowofthewateriscontrolledbyatimer
controlled solenoid.
The membrane tube separates moisture from air
by a pressure differential across semipermeable
bers.Thewatervaporandasmallamountof
theairpermeatethroughthelterwallsleaving
the exiting air with a reduced water vapor
content of -45°C (-50°F) dewpoint. The air that
permeatesthroughtheberspurgesthewater
vapor out of the tubes vent ports.
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.
