INGERSOL RAND COMPRESSED AIR DRYER MODEL TS110
The High Temperature thermostat (ST) of the above dryer trips (set at 120 degree centigrate ) and in the screen appears the indication St. (High Discharge Temperature).
The first action I took is to change the rotation of Copeland scroll compressor by reversing two of the three wires feeding the dryer, but the problem remain the same.
I recovered the refrigerant and charged it again the correct quantity of refrigerant (2,3Kg – R407C). But the problem is not solve.
The discharge pressure is not rise and the condenser fan does not start (set at 18Bar). The Current draw is substantially reduced compared to tabulated values.
The type of compressor used in the dryer is three-phase Copeland scroll compressor.
Do you have any idea what is the problem. Is compressor faulty?.
