RefComp SW3 Series Semi-Hermetic Screw Compressor

RefComp SW3 Series Semi-Hermetic Screw Compressor

The SW3 series semi‑hermetic screw compressors are renowned for their high efficiency, broad operating range, and reliability. They not only meet traditional industrial refrigeration requirements but also excel across a variety of emerging applications. Typical use cases include:

• Cold Storage Systems: Constant‑temperature storage for large‑scale food, pharmaceuticals, and chemical raw materials

• Cold Chain Logistics: End‑to‑end temperature control for refrigerated transport vehicles and containers

• Seafood Quick‑Freezing: On‑board quick‑freeze decks and shore‑based seafood processing facilities

• Fruit & Vegetable Preservation: Mountain orchards, greenhouse operations, and urban retail cold‑storage warehouses

• Ice‑Making Systems: Commercial ice rinks, hotels, and industrial ice‑production equipment

• Environmental Cooling: Precision climate control for electronics workshops, laboratories, and exhibition halls

• Pharmaceutical Refrigeration: Low‑temperature storage for vaccines, blood products, and biological samples

• Dairy Processing: Temperature regulation for milk pasteurization and cheese maturation

• Chemical Cooling: Cooling for reactors, distillation columns, and solvent‑recovery systems

• Data Center Cold Aisles: High‑density heat‑load management in server rooms

• Brewery Cooling: Temperature control for fermentation tanks, storage vessels, and maturation phases

With compatibility for refrigerants such as R22 R507A and R404A, and an operating range from –50 °C to +10 °C, the SW3 series delivers stable, efficient, and flexible refrigeration power solutions across industries.

The SW3 series compressors are divided into two sub-series: the SW3H for medium and high-temperature applications and the SW3L for low-temperature applications, offering a total of 34 models. These compressors have a displacement range of 118 to 1100 m³/h (@2960 rpm) and a power range of 30 to 400 HP. They are compatible with a variety of refrigerants, including R507A and R404A.

• RefComp design of asymmetric screw rotor profile, achieving excellent sealing performance and smooth operation of the compressor.
• Highly integrated components such as filters, shut-off valves, and temperature sensors result in a compact structure and higher reliability.
• Equipped with motor protection module, dynamic monitoring and operation information tracking, realizing predictable reminders and safety protection.
• Pairs of bearing combination to ensure the long service life, high load and low noise.
• Built-in precision suction filter, easy to replace and maintain.
• Adjustable cooling capacity to make step/stepless control.
• Special structural design and spatial layout, using suction refrigerant gas to effectively cool the motor.
• Suction/Discharge shut-off valve can be rotated, simple and flexible installation.
