The AC screw compressor uses matched bearing assemblies to support axial and radial rotor loads. Precision rolling elements and wear-resistant raceways help reduce friction, vibration and operating noise.
Six series-connected PTC thermistors work with the INT69 SNY module to monitor motor temperature, providing protection against overheating, reverse rotation and phase loss in this semi-hermetic screw compressor.
An internal safety valve connects the high- and low-pressure sides to help prevent excessive pressure differentials. This protective arrangement supports safer operation of the AC screw compressor.
A built-in 100 μm suction filter captures impurities from incoming refrigerant gas to protect the motor. Its accessible suction-side position simplifies inspection and replacement during routine maintenance.

Q1: How should capacity control be integrated with an HVAC system?
The compressor series supports 100%, 75%, 50% and 25% capacity stages, along with stepless regulation from 100% to 25%. Confirm the supplied control configuration and ensure the HVAC controller can coordinate capacity adjustments with changing cooling demands.
Q2: What should be checked before commissioning?
Verify the oil level, electrical wiring, valve positions and motor protection connections. Complete system leak testing and evacuation, and ensure the crankcase heater has operated according to the manufacturer's pre-start instructions.
Q3: What causes an AC screw compressor to trip repeatedly?
Check the INT69 SNY fault indication, motor temperature, power supply and operating pressures to identify possible electrical or refrigeration system problems. Correct the underlying fault before restarting rather than bypassing the protection circuit.
Q4: What routine maintenance is recommended for a semi-hermetic screw compressor?
Monitor lubricant condition, suction and discharge pressures, operating temperature and unusual noise or vibration. Follow the manufacturer's maintenance schedule and inspect the refrigeration circuit for conditions that could affect compressor operation.
