The SW3L-10500 HVAC screw compressor features RefComp's asymmetric 5/6-tooth rotor profile, promoting smooth rotor engagement and reduced vibration. Its optimized geometry helps improve compression efficiency and supports stable mechanical operation.
This RefComp screw compressor integrates key components within a compact housing, simplifying equipment layout and system integration. Optimized internal gas passages help reduce suction resistance and flow losses, supporting smoother refrigerant flow.
The semi-hermetic screw compressor incorporates a built-in 100 μm suction filter that captures impurities from incoming refrigerant gas before they reach the motor. This helps protect internal components from contamination and reduces the risk of damage caused by foreign particles.
The 360° rotatable suction and discharge shut-off valves allow flexible piping orientation, making installation more convenient in different equipment layouts. An integrated discharge check valve helps prevent refrigerant backflow during shutdown.

Q1: Is the SW3L-10500 suitable for an air-conditioning or chiller system?
The SW3L-10500 belongs to RefComp's low-temperature refrigeration range. Before selecting it as an HVAC screw compressor, verify that the required refrigerant, cooling capacity and operating temperatures fall within its approved operating envelope.
Q2: How should the capacity control system be integrated?
For a screw compressor for process cooling, confirm whether the ordered configuration uses stepped or stepless capacity regulation. Ensure the controller signals and slide-valve control connections match the selected configuration before commissioning.
Q3: What lubrication requirements should be considered before installation?
The SW3 series does not include an integrated oil separator, so an appropriately matched external oil separation and return system is required. Check the oil connections, filtration and flow-protection devices against the manufacturer's installation requirements.
Q4: What should I check if the motor protection module triggers an alarm?
If this HVAC screw compressor stops following an INT69 SNY alarm, inspect motor temperature, phase sequence, power supply and protection wiring. Identify and correct the underlying fault before restarting the compressor.
