Flexible Capacity Regulation
The AC screw compressor supports four-step capacity control at 25%, 50%, 75% and full load, or stepless adjustment from 25% to full load, helping match output to changing refrigeration demands.
-
Compact High-Pressure Housing
The 25-bar housing features optimized internal gas passages to reduce flow resistance and support efficient refrigerant circulation. Its integrated construction makes this low-temperature screw compressor convenient for system installation.
-
INT69 SNY Motor Protection
The 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.
-
High-Density Suction Filtration
A built-in 100 μm suction filter removes impurities from incoming refrigerant gas, helping protect the motor and maintain clean refrigerant flow in air conditioning screw compressor applications.

Q1: How should I choose between four-step and stepless capacity control?
For an AC screw compressor, consider the frequency and range of load variations in your refrigeration system. Stepless regulation offers more continuous adjustment, while four-step control provides defined capacity stages.
Q2: What electrical details should be confirmed before ordering?
Confirm the site's three-phase power supply, voltage, frequency and motor starter configuration. The electrical protection and Y/Δ starting arrangement should be compatible with the selected AC refrigeration compressor.
Q3: What should be checked before commissioning in a low-temperature application?
Verify the operating conditions against the manufacturer's selection data, and check refrigerant piping cleanliness, oil return arrangements and control connections before startup.
Q4: What operating records are useful when evaluating compressor performance?
Keep records of suction and discharge pressures, operating temperatures, motor current and protection alarms. Comparing these readings with the commissioning baseline helps identify abnormal system conditions.
