  • Common faults and causes of screw chillers Jan 12, 2022
    Common faults and causes of screw chillers 1. High voltage fault The compressor discharge pressure is too high, causing the high pressure protection relay to act. The compressor discharge pressure reflects the condensing pressure. If the pressure is too high for a long time, it will cause the compressor running current to be too large, which will easily burn the motor, and also easily cause damage...
