The Refcomp SW3L-6000 is a 60HP semi-hermetic screw type refrigeration compressor engineered for reliable performance with R22 and R404A refrigerants. Its asymmetric rotor geometry, compact housing, and integrated protection module deliver efficient compression, flexible installation, and dependable long-term operation.
The SW3L-6000 screw type refrigeration 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 semi-hermetic screw compressor combines 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 circulation.
The RefComp screw compressor features 360° rotatable suction and discharge shut-off valves, making piping arrangements more flexible for different installation layouts. An integrated discharge check valve also helps prevent refrigerant backflow during shutdown.
The INT69 SNY module works with PTC temperature sensors to monitor motor overheating, reverse phase sequence and phase loss. Operating-status feedback helps identify abnormal conditions, supporting faster troubleshooting and reducing the risk of motor damage.

Q1: How do I select the SW3L-6000 for low-temperature refrigeration?
When selecting a screw type refrigeration compressor, provide the required cooling capacity, refrigerant, evaporating and condensing temperatures, power supply and expected load conditions. Verify that the model operates within the approved system requirements before ordering.
Q2: How should I choose the appropriate capacity control configuration?
For a variable capacity screw compressor, stepped regulation suits systems with defined load stages, while stepless regulation allows finer output adjustment. Confirm the required control mode and its compatibility with the refrigeration controller before ordering.
Q3: What should be checked in the lubrication system before commissioning?
The SW3L series does not include an internal oil separator, so an appropriate external oil separation and return arrangement is required. Check the oil connections, filtration and flow-monitoring devices against the system design before startup.
Q4: What should I consider when replacing an existing compressor?
When replacing a screw type refrigeration compressor, compare the mounting dimensions, suction and discharge connections, oil-line fittings, motor starter and capacity-control interface. These checks help identify potential compatibility issues before installation.
