Air Cooled Air/Fluid Flow; Air Cooled Fluid Coolers - Quincy Compressor QMA Series Instruction Manual

Figure 2-1 Air-cooled Air/Fluid Flow
is injected into the early stage of the compression c@e
to seal clearances and lubricate the rotors.
Air-Cooled Fluid Coolers
The air-cooled fluid cooler is of the finned tube design.
Ambient air is forced vertically through the fins by a
motor driven fan, cooling the fluid in the tubes. To
maintain proper compressor operation, the temperature
of the ambient air should not exceed the temperatures
iisted in the Q&4 Specifkations. The cooler fins must
be kept clean at all times. Fluid leaving the cooler
passes through a thermal mixing valve before traveling
onto the compressor. The purpose of the thermal valve
is to mix fluid from the cooler with non-cooled fluid to
maintain a minimum discharge temperature at the
compressor of 180 degrees F.
