High discharge temperature is the result of temperatures in the compressor head and cylinders becoming so hot that the oil loses its ability to lubricate properly. This causes rings, pistons and cylinders to wear resulting in blow by, leaking valves, and metal debris in the oil.
How do you fix high temperature discharge?
Discharge temperature is greatly affected by the compression ratio, the larger the compression ratio, the higher the discharge temperature. Reducing the compression ratio can significantly reduce the discharge temperature, including increasing the suction pressure and reducing the discharge pressure.
What should my discharge temp be?
The compressor’s discharge temperature should be measured about 1 to 2 inches away from the compressor on the discharge line. This discharge temperature should never exceed 225°F. Carbonization and oil breakdown can occur if compressor discharge temperatures exceed 225°.
