The RC2-300B screw type refrigeration compressor is designed for medium- and large-capacity commercial and industrial cooling applications. Utilizing a twin-shaft rotary displacement mechanism, it provides continuous cooling output and stable operation under varying thermal loads.

Patented 5:6 Screw Rotor Geometry & High-Efficiency Motor
Featuring patented 5:6 asymmetric screw rotors machined with high-precision CNC centers, this screw type refrigeration compressor reduces internal gas bypass and mechanical friction. Driven by an integrated 3-phase, 2-pole squirrel-cage induction motor cooled by suction gas, the unit maintains high power efficiency across both 50Hz and 60Hz system setups.

Dynamic Capacity Regulation & Refrigerant Flexibility
To match changing cooling loads and minimize power consumption during part-load operation, the compressor includes an internal hydraulic slide valve. It offers 4-stage step load regulation (25% - 50% - 75% - 100%) and continuous stepless modulation (25% - 100%). Designed for broad compatibility, this screw type refrigeration compressor operates with R22, R407C, R404A, and R507A refrigerants.

Heavy-Duty Housing & Comprehensive Mechanical Protection

• Double-Walled Cast Iron Housing: Built from FC25 gray cast iron with inner reinforcement ribs to suppress operational noise and eliminate casing expansion under high pressure.
• Flange-On Oil Separator: Cast from high-strength FC500 ductile iron to handle high pressure while ensuring low pressure drop and high oil separation efficiency.
• Extended Bearing Assembly: Combines 10 radial and axial bearings with an alpha balance piston to support high axial loads and ensure long-term mechanical stability.
• Integrated Electronic Safeguards: Standard PTC thermistor modules continuously monitor motor coil heat, discharge gas temperatures, phase loss, and phase sequence errors.

• Commercial Cold Storage: Suitable for medium- and low-temperature cold storage warehouses, logistics centers, and cold chain distribution hubs.
• Industrial Liquid Chillers: Designed for large water-cooled and air-cooled liquid chiller plants requiring flexible part-load capacity control.
• Food Processing & Quick Freezing: Ideal for blast freezing tunnels, meat processing operations, and food preservation facilities.
• HVAC & Commercial Air Conditioning: Suitable for centralized commercial air conditioning systems and industrial process air conditioning units.
