-
Optimized Asymmetric Rotor Design
RefComp's 5/6 asymmetric rotor profile helps the screw AC compressor maintain smooth compression while reducing gas pulsation, vibration and operating noise.
-
Integrated Oil Separation System
This semi-hermetic screw compressor features a built-in multi-stage oil separator with layered oil-mist filtration, achieving a stated separation efficiency of 99.85% to minimize oil carryover and maintain internal lubrication.
-
Flexible Shut-Off Valve Configuration
The air conditioning screw compressor features 360° rotatable suction and discharge shut-off valves for convenient piping connections. An internal discharge check valve helps prevent refrigerant backflow during shutdown.
-
Compact High-Pressure Housing
The screw AC compressor features a 25-bar housing with optimized internal gas passages to reduce flow resistance. Its integrated construction combines the suction filter, shut-off valve and temperature sensor.

For screw AC compressor selection, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, and operating frequency. This 240 HP screw compressor has a displacement of 910 m³/h at 50 Hz and 1,092 m³/h at 60 Hz, but actual cooling performance must be verified against manufacturer selection data.
Check the mounting dimensions, piping connections, lifting access and available service clearance against the installation drawings. The unit weighs 1,400 kg, so the supporting structure and lifting equipment must be suitable for safe installation.
The HVAC screw compressor series specifies 100%, 75%, 50% and 25% capacity stages, with stepless regulation from 100% to 25%. Confirm the supplied control configuration and ensure the system controller supports the required regulation method.
Verify refrigerant compatibility throughout the system and follow the manufacturer's oil replacement procedures before making any conversion.
