The RC2-310B screw air conditioning compressor is designed for high-capacity commercial HVAC and cooling systems. Featuring an advanced twin-shaft rotary displacement structure, it ensures continuous cooling output and operational stability under variable load conditions.

Patented 5:6 Screw Rotor Profile & High-Efficiency Motor

Equipped with patented 5:6 asymmetric screw rotors manufactured using precision CNC grinding equipment, this screw air conditioning compressor minimizes internal gas recirculation and mechanical friction. Its integrated 3-phase, 2-pole squirrel-cage induction motor is cooled directly by suction gas to maintain peak energy efficiency across 50Hz and 60Hz power supplies.

Dynamic Capacity Regulation & Refrigerant Flexibility

To optimize energy usage during part-load operation, the internal hydraulic slide valve supports 4-stage step capacity regulation (35% - 50% - 75% - 100%) as well as continuous stepless modulation (35% - 100%). Operating smoothly with R22, R407C, R404A, and R507A, this screw air conditioning compressor easily integrates into diverse chiller and air conditioning plant designs.

Rigid Structural Housing & Integrated Protections

• Double-Walled Cast Iron Housing: Built from FC25 gray cast iron with inner reinforcement ribs to suppress operational noise and eliminate casing distortion under pressure.
• Flange-On Oil Separator: Cast from FC500 ductile iron to handle high system pressure while maintaining low pressure drop and high oil separation efficiency.
• Extended Bearing Assembly: Combines 10 radial and axial bearings with an alpha balance piston to support axial loads and maximize bearing service life.
• Integrated Safety Features: Standard PTC thermistor modules continuously monitor motor coil heat, discharge gas temperatures, phase sequence mismatch, and phase loss.

• Commercial HVAC & Air Conditioning: Ideal for commercial central air conditioning plants, large rooftop units, and building HVAC systems.
• Water & Air-Cooled Liquid Chillers: Designed for liquid chiller installations requiring high part-load efficiency and flexible capacity modulation.
• Industrial Process Air Conditioning: Provides stable temperature and humidity control for pharmaceutical plants, cleanrooms, and manufacturing facilities.
• Commercial Cold Storage: Suitable for medium- and low-temperature cold rooms, cold storage logistics facilities, and food preservation warehouses.
