the stator and also between the rotors them-
selves.
3. Acts as a lubricating film between the rotors
allowing one rotor to directly drive the other,
which is an idler.
After the air/fluid mixture is discharged from the
compressor unit, the fluid is separated from the air.
At this time, the air flows through an aftercooler and
separator then to your service line while the fluid is
being cooled in preparation for reinjection.
2.4 COMPRESSOR COOLING AND LUBRICATION
SYSTEM, FUNCTIONAL DESCRIPTION
Refer to Figures 2-3 and 2-4. The Cooling and
DESCRIPTION
Lubrication System (air-cooled version) consists
of a fan, fan
aftercooler/fluid cooler, full flow fluid filter, ther-
mal valve, and interconnecting piping and tub-
ing.
Standard thermal valve temperature is 175ºF
(79ºC). Thermal valve temperature is 190ºF (88ºC)
for HH, XH and 24KT machines.
For water-cooled models, two shell and tube heat
exchangers are substituted for the radiator-type
cooler listed above.
