Hanbell RC2-470B-Z RC2-470B-W Refrigeration Screw Compressor for Commercial Cold Room
Product Overview
The RC2-470B refrigeration screw compressor is designed to deliver reliable cooling performance and high volumetric efficiency for large-scale industrial and commercial cooling applications. Utilizing a twin-shaft rotary displacement mechanism, it provides continuous operation under severe load conditions.
Patented 5:6 Screw Rotors & High-Efficiency Motor
Featuring patented 5:6 asymmetric screw rotors manufactured using precision CNC grinding technology, this refrigeration screw compressor suppresses internal gas bypass and mechanical drag. Its integrated 3-phase, 2-pole squirrel-cage induction motor is cooled by suction refrigerant gas to maintain optimal energy efficiency across both 50Hz and 60Hz electrical frequencies.
Flexible 4-Stage Load Modulation & Multi-Refrigerant Compatibility
To align power input with fluctuating cooling demands, the internal hydraulic slide valve provides 4-stage step capacity regulation (25% - 50% - 75% - 100%) and continuous stepless modulation (25% - 100%). Compatible with R22, R407C, R404A, and R507A, the refrigeration screw compressor easily adapts to diverse low- and medium-temperature system configurations.
Durable Mechanical Structure & Integrated Protections
- Double-Casing Rotor Housing: Constructed from FC25 gray cast iron with internal reinforcement ribs to prevent housing distortion and reduce operating noise.
- Direct Flange-On Oil Separator: Made from FC500 ductile iron to handle high system pressures, maintain low pressure drop, and ensure proper lubricant viscosity.
- 10-Bearing Heavy-Duty Assembly: Combines 10 radial and axial bearings with an alpha balance piston to absorb axial thrust and prolong mechanical life.
- Comprehensive Protective Monitoring: Standard PTC thermistors continuously monitor motor coil heat, discharge gas temperatures, phase loss, and phase sequence errors.
Applications
- Commercial Cold Storage & Distribution: Ideal for large low-temperature cold storage hubs, refrigerated warehouses, and cold chain logistics facilities.
- Industrial Process Chilling: Provides stable temperature control for chemical plants, pharmaceutical lines, and heavy-duty manufacturing fluid cooling.
- Food Freezing & Processing: Designed for quick-freezing tunnels, blast freezers, and meat or seafood processing operations.
- Large Chiller Installations: Well-suited for water-cooled and air-cooled liquid chiller plants operating under dynamic load demands.
