Hanbell RC2-510B-Z RC2-510B-W High Capacity Cooling HVAC Screw Compressor
Product Overview
The RC2-510B semi hermetic screw compressor is designed for large-capacity commercial air conditioning, process cooling, and industrial refrigeration systems. Driven by a twin-shaft rotary displacement mechanism, it provides continuous cooling output and maximum volumetric efficiency under demanding operating conditions.
Key Features
Patented 5:6 Screw Rotor Profile & High-Efficiency Motor
Featuring precision CNC-machined 5:6 asymmetric screw rotors, this semi hermetic screw compressor minimizes internal gas recirculation and mechanical drag. Its integrated 3-phase, 2-pole squirrel-cage induction motor is directly cooled by suction refrigerant gas to maintain optimal energy efficiency across 50Hz and 60Hz power supplies.
Versatile Capacity Control & Multi-Refrigerant Compatibility
To match dynamic cooling loads and minimize power consumption during part-load operation, the compressor includes an internal hydraulic slide valve. It supports 4-stage step capacity regulation (25% - 50% - 75% - 100%) and continuous stepless modulation (25% - 100%). Compatible with R22, R407C, R404A, and R507A, this semi hermetic screw compressor integrates smoothly into diverse cooling plant designs.
- Double-Walled Cast Iron Housing: Built from FC25 gray cast iron with inner reinforcement ribs to suppress operational noise and prevent casing distortion under high pressure.
- Flange-On Oil Separator: Cast from high-strength FC500 ductile iron to manage high working pressures while maintaining low pressure drop and high oil separation efficiency.
- Heavy-Duty Bearing System: Combines 10 radial and axial bearings with an alpha balance piston to absorb axial thrust forces and extend service life.
- Integrated Safety Protections: Standard PTC thermistor modules continuously monitor motor coil temperature, discharge gas heat, phase loss, and phase sequence errors.
Applications
- Large Commercial HVAC & Chillers: Ideal for central commercial air conditioning plants, rooftop units, and large water-cooled or air-cooled liquid chiller installations.
- Industrial Cold Storage Facilities: Well-suited for large low-temperature cold rooms, cold storage logistics hubs, and food preservation distribution centers.
- Quick Freezing & Food Processing: Delivers high displacement for quick-freezing tunnels, blast freezers, and commercial meat or seafood processing operations.
- Process Cooling Systems: Provides stable, continuous cooling performance for heavy manufacturing, chemical, and pharmaceutical processing lines.
