Flexible Capacity Regulation
The refrigeration screw compressor supports four-step capacity control at 25%, 50%, 75% and 100%, or stepless adjustment from 25% to full load, helping match compressor output to changing cooling demands.
-
Compact High-Pressure Housing
The semi-hermetic screw compressor features a 25-bar housing with optimized internal gas passages to reduce flow resistance. Its integrated construction accommodates key components for convenient system installation.
-
Star-Delta Motor Starting
The standard Y/Δ motor configuration supports star-delta starting to manage motor startup current. The electrical configuration is available for the specified three-phase power supply requirements.
-
Flexible Shut-Off Valve Configuration
The semi-hermetic refrigeration compressor features 360° rotatable suction and discharge shut-off valves for flexible piping arrangements. An internal discharge check valve helps prevent refrigerant backflow during shutdown.

Q1: How can I confirm whether this compressor is suitable for my low-temperature application?
For refrigeration screw compressor selection, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. The low-temperature screw compressor should be checked against manufacturer performance data at the actual operating conditions.
-
Q2: What should be checked before connecting the compressor to an existing refrigeration system?
Verify the suction, discharge and oil-line connections against the system piping drawings. Also check piping cleanliness, oil return arrangements and available maintenance space.
-
Q3: Can the compressor output adapt to changing refrigeration loads?
Yes. For an industrial refrigeration screw compressor installation, the available four-step or stepless capacity regulation can be selected according to the system load profile and controller compatibility.
-
Q4: What should I do if the motor protection module trips during operation?
Check the INT69 SNY protection indication, power supply phase sequence, PTC sensor circuit and motor temperature. Identify and correct the underlying fault before resetting the protection module.
