IR Thermal Element 39412788 Screw Air Compressor Spare Parts


Some rotary screw compressors are furnished with a thermal or bypass valve in the coolant (oil) piping system. This valve is controlled by a thermostat and will bypass the oil cooler when necessary to achieve and maintain a minimum oil temperature.


This process helps protect the compressor during cold weather startups. It is critical to make sure the thermal valve is operating properly during startup as well as when the compressor reaches its normal operating temperature.


A simple test is to remember that warm oil should be returning through the thermal valve and oil filter to the airend within a few minutes of startup. The oil will not be diverted to the oil cooler until the oil temperature reaches the minimum operating temperature.

The thermostatic valve can control the compressor operation temperature according to the oil temperature.


If you run too hot you’ll fry the oil, decrease efficiency and burn out other components. If you run too cold, you’ll never get hot enough to boil off the liquid water that dropped out of the air when it was compressed. Too much liquid water in the oil will cause airend failure.
