Compressor Oil Cooler; Radiator - Ingersoll-Rand HP600A-WCU Operating, Maintenance & Parts Manual

COMPRESSOR OIL COOLER
The compressor lubricating and cool-
ing all is cooled by means of the fin and
tube-type oil cooler, located beside
the radiator. The lubricating and cool-
ing oil, flowing Intemally through the
core section, Is cooled by the air
stream from the cooling fan flowing
past the core section. When grease,
oil and dirt accumulate on the exterior
surfaces of the oil cooler, its efficiency
is impaired.
Each month
it
Is recommended that
the oil cooler be cleaned by directing
compressed air which contains a non-
flammable safety solvent through the
core of the oil cooler. This should re-
move the accumulation of grease, oil
and dirt from the exterior surfaces of
the oil cooler core so that the entire
cooling area can transmit the heat of
the lubricating and cooling oil to the air
stream.
In the event deposits, such as sludge
and lacquer, accumulate in the oil
cooler to the extent that its COOlingeffi-
ciency is impaired, a resulting high
discharge air temperature is likely to
occur, causing shut down of the unit.
To correct this situation it will
be
nec-
essary to clean
it
using a cleaning
compound In accordance with the
manufacturer's recommendations.
Use only a dependable cleaning
compound.
This is of prime Importance because
different cleaners vary in concentra-
tion and chemical composition. After
completing the cleaning procedure,
the oil cooler must be flushed before
returning to service.

for proper coolant.
The engine cooling system is filled
at the factory with a 50/50 mixture of
water and ethylene glycol. This per-
manent type antifreeze contains
~st inhibitors and provides protec-
tion to -35° F (-37°C).
