Flexible Capacity Regulation
The screw type refrigeration compressor supports four-step capacity control at 25%, 50%, 75% and 100%, or stepless adjustment from 25% to 100%, helping match compressor output to changing refrigeration loads.
-
INT69 SNY Motor Protection
An INT69 SNY protection module works with six series-connected PTC thermistors to monitor motor temperature and provide protection against overheating, reverse rotation and phase loss in this semi-hermetic screw compressor.
-
Star-Delta Motor Starting and Cooling
The compressor adopts star-delta motor starting to manage startup current. Suction-gas cooling helps maintain suitable motor operating temperatures during operation.
-
Flexible Shut-Off Valve Configuration
The suction and discharge shut-off valves can rotate through 360°, offering greater flexibility in piping layout and installation. An internal discharge check valve helps prevent refrigerant backflow during shutdown.

Q1: How can I confirm whether this compressor is suitable for my refrigeration system?
For screw type refrigeration compressor selection, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The final selection should be verified against manufacturer performance data.
Q2: What should be considered when connecting the compressor to an existing refrigeration system?
Check the suction, discharge and oil-line connections against the existing piping layout. Ensure the refrigerant circuit, connection dimensions and oil return arrangement are compatible before installation.
Q3: What should be checked before the first startup?
Verify the motor starter wiring, phase sequence, oil level, valve positions and protection settings. Complete system leak testing and evacuation before commissioning.
Q4: What should I check if the motor protection module trips during operation?
If the screw type refrigeration compressor trips, check the power supply, phase sequence, motor temperature and PTC sensor connections. Correct the underlying fault before resetting the protection module and restarting.
