Hanbell RC2-580B-Z RC2-580B-W Screw AC Compressor for Rooftop Refrigeration Unit

The RC2-580B screw AC compressor is engineered for large-scale commercial air conditioning systems and high-tonnage industrial chiller applications. Designed to withstand heavy thermal loads, it combines precise volumetric control with high mechanical reliability for continuous cooling operations.

High-Precision 5:6 Screw Rotors & Energy-Efficient Drive
Utilizing patented 5:6 asymmetric rotor profiles manufactured via high-precision CNC grinding, this screw AC compressor minimizes internal gas slip and mechanical friction. The integrated 3-phase, 2-pole squirrel-cage induction motor is directly cooled by incoming suction refrigerant gas, ensuring high electrical efficiency across both 50Hz and 60Hz power grids.

Dynamic Capacity Regulation & Refrigerant Flexibility
To maintain optimal power performance under varying heat loads, the compressor includes 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 refrigerants, this screw AC compressor provides maximum integration versatility for international HVAC OEMs.

• Reinforced Dual-Chamber Casing: Cast from high-density FC25 gray iron with internal stiffening ribs to suppress operational acoustic vibration and maintain dimensional stability under high working pressures.
• Direct Flange-On Separator: Constructed from FC500 ductile iron to ensure high oil separation efficiency, low pressure drop, and steady lubricant delivery.
• 10-Bearing Heavy-Duty Setup: Features oversized radial and axial bearings paired with an α balance piston to absorb axial thrust forces and maximize operational service life.
• PTC Protection System: Integrated thermistor modules monitor motor winding temperature, discharge gas heat, phase sequence errors, and phase loss in real time.

• Commercial HVAC Systems: Ideal for large commercial building central air conditioning systems, shopping complex HVAC networks, and rooftop units.
• Water & Air-Cooled Liquid Chillers: Designed for high-tonnage industrial and commercial chiller packages requiring precise step and stepless part-load management.
• District Cooling & Thermal Storage: Delivers continuous displacement capacity for large-scale central water cooling plants and thermal energy storage infrastructure.
• Industrial Process Air Conditioning: Provides consistent cooling for environmental control units in pharmaceutical plants, data centers, and cleanroom facilities.
