The control system can easily be adjusted for pressures
from 80 to 125 psig (5.6 to 8.6 bar) for standard machines,
from 80 to 150 psig (5.6 to 10.3 bar) for “H” machines and
from 80 psig to 200 psig (5.6 to 13.8 bar) for “HH”
machines. The compressor unit is driven by an industrial
diesel engine designed to provide enough horsepower to
provide an adequate reserve under rated conditions.
Refer to the Engine Operator’s Manual for a more
detailed description of the engine. The engine cooling
system is comprised of a radiator, charge air cooler, high
capacity fan, and thermostat. The high capacity fan pushes
air through the radiator to maintain the engine’s specied
operating temperature. The same fan also cools the uid in
the compressor cooling and lubrication system.
