THERMOSTAT KIT 40 DEGREE C FOR OIL INJECTED SCREW COMPRESSOR

The Thermostat Kit 40 Degree C (2901161600) is a service kit for oil-injected screw compressors, supplying the thermostatic valve that regulates oil temperature. In these compressors, oil is circulated through the compression element to seal, cool, and lubricate it, and the thermostat controls how much of that oil passes through the oil cooler. Below its 104 °F (40 °C) set point the valve routes oil around the cooler so the compressor reaches working temperature quickly; as the oil warms, the valve opens and directs it through the cooler to prevent overheating and keep the compressor running smoothly.

This kit is the correct part for GA-range oil-injected screw compressors, fitted as a service replacement at intervals of up to 8,000 hours. Thermostat kits are matched to the machine by opening temperature, so check the marking on the valve you are taking out and confirm it calls for the 104 °F (40 °C) setting this kit provides, because a thermostat that opens at a different temperature will route oil to the cooler too early or too late. If the old valve is unmarked or already out of the compressor, tell us your GA model and we will confirm which opening temperature it takes.
