Flexible Capacity Regulation
This HVAC screw 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 cooling loads.
-
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. The filter can be inspected during routine maintenance.
-
Motor Starting and Cooling
The semi-hermetic screw compressor supports partial-winding or star-delta starting to reduce starting current. Suction-gas cooling helps maintain suitable motor temperatures during operation.
-
Flexible Shut-Off Valve Configuration
The HVAC screw compressor features 360° rotatable suction and discharge shut-off valves for flexible piping arrangements. An internal discharge check valve helps prevent refrigerant backflow when the compressor stops.

Q1: What information should I provide when selecting an HVAC screw compressor?
Provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, power supply and application details. The final selection should be verified against the manufacturer's performance data.
Q2: How can compressor capacity control be matched to changing building loads?
Choose between four-step and stepless regulation according to the system's load variations and control requirements. Confirm that the selected control arrangement is compatible with the HVAC system controller.
Q3: What should be checked before connecting the compressor to an existing refrigeration system?
Compare the suction, discharge and oil-line connections with the system piping drawings. Also check piping cleanliness, oil return arrangements and available maintenance space before installation.
Q4: What operating conditions should be considered for high-temperature applications?
Check the refrigerant, ambient temperature, evaporating and condensing conditions, and discharge temperature against the manufacturer's application limits. Confirm the suitability of the specific operating conditions using model-specific selection data.
