The RC2-410B HVAC screw compressor is engineered for high-demand commercial air conditioning and industrial chilling systems. Driven by a twin-shaft rotary displacement design, it delivers high displacement volume and consistent cooling performance under intensive thermal loads.

Precision Rotor Profile & Energy Efficient Motor
Utilizing patented 5:6 asymmetric screw rotors produced on high-precision CNC machining centers, this HVAC screw compressor minimizes internal pressure leakage and mechanical drag. Its integrated 3-phase, 2-pole squirrel-cage motor is cooled directly by suction refrigerant gas, ensuring maximum energy efficiency across both 50Hz and 60Hz electrical frequencies.

Flexible 4-Stage Capacity Control & Refrigerant Adaptability
To optimize part-load energy consumption in large HVAC installations, the internal slide valve allows 4-stage step capacity regulation (25% - 50% - 75% - 100%) and continuous stepless modulation (25% - 100%). Compatible with R22, R407C, R404A, and R507A, this HVAC screw compressor seamlessly integrates into diverse refrigeration and chiller plant architectures.

• Double-Walled Cast Iron Housing: Built from FC25 gray cast iron with inner rib reinforcement to absorb operational vibration and suppress noise.
• Direct Flange-On Oil Separator: Cast from FC500 ductile iron for high-pressure durability, low pressure drop, and efficient oil separation.
• Extended Bearing Assembly: Features 10 radial and axial bearings paired with an alpha axial balance piston to balance shaft thrust forces and prolong operating lifespan.
• Perceptive Protection Module: Standard PTC thermistors continuously monitor motor coil heat, discharge gas temperatures, phase sequence, and phase loss.

• Large Commercial HVAC Systems: Ideal for centralized air conditioning systems, rooftop packages, and large commercial building HVAC units.
• Liquid Chiller Plants: Designed for air-cooled and water-cooled chiller systems requiring high part-load efficiency and flexible load matching.
• Commercial Cold Storage: Suitable for medium- and low-temperature cold storage warehouses, cold chain distribution hubs, and food processing plants.
• Industrial Process Cooling: Provides stable, continuous cooling performance for manufacturing, chemical, and pharmaceutical processing lines.
