The RC2-260B screw AC compressor is engineered to provide efficient and reliable performance for medium- to large-scale commercial air conditioning and chilling systems. Powered by a twin-shaft rotary displacement design, it ensures smooth operation and consistent temperature regulation under heavy operational demands.

Utilizing precision CNC-machined 5:6 asymmetric screw rotors, this screw AC compressor minimizes internal gas recirculation and mechanical friction. Its integrated 3-phase, 2-pole squirrel-cage induction motor is directly cooled by suction refrigerant gas, enabling maximum energy efficiency across 50Hz and 60Hz power supplies.

To match dynamic system demands and lower energy consumption during part-load conditions, the compressor features an internal hydraulic slide valve supporting 4-stage step regulation (25% - 50% - 75% - 100%) and continuous stepless modulation (25% - 100%). Compatible with R22, R407C, R404A, and R507A, this screw AC compressor adapts seamlessly to diverse HVAC and industrial cooling systems.

• Double-Walled Cast Iron Housing: Built from FC25 gray cast iron with internal reinforcement ribs to absorb operational vibration and suppress noise.
• Direct Flange-On Oil Separator: Constructed from high-strength FC500 ductile iron to ensure high oil separation efficiency, minimal pressure drop, and steady oil viscosity.
• Heavy-Duty Bearing System: Integrates 10 axial and radial bearings with an alpha balance piston to support high load capacity and prolong bearing service life.
• Integrated Electronic Safeguards: Standard PTC thermistor modules monitor motor coil temperature, discharge line heat, phase loss, and phase sequence errors.

• Commercial Air Conditioning: Ideal for large commercial HVAC installations, rooftop air handling units, and central air conditioning plants.
• Water-Cooled Liquid Chillers: Designed for industrial and commercial chiller systems requiring flexible part-load capacity control.
• Cold Storage Facilities: Suitable for medium- and low-temperature cold rooms, cold storage logistics centers, and food distribution warehouses.
• Industrial Process Cooling: Delivers stable, uninterrupted cooling for chemical, pharmaceutical, and plastic manufacturing processes.
