Hanbell RC2-370B-Z RC2-370B-W Heavy Duty Screw Refrigeration Compressor
Product Overview
The RC2-370B screw refrigeration compressor is engineered for large-capacity industrial refrigeration and chiller systems demanding high thermal stability and continuous operation. Utilizing patented 5:6 asymmetric screw rotors, it ensures consistent displacement and minimal operational noise under high working pressures.
Economizer Sub-Cooling Integration
This compressor features a dedicated economizer (sub-cooler) connection port to maximize system cooling capacity with minimal energy consumption. The specially engineered gas flow passageway on the slide valve maintains stable intermediate pressure, enabling effective sub-cooling even during part-load conditions.
VFD-Ready Motor Architecture
Built with F-class insulation and cooling guide vanes on the motor casing, the semi-hermetic motor is cooled directly by suction gas. It supports part winding (PWS), star-delta (Y-Δ), and direct-on-line (DOL) starting, with optional Variable Frequency Drive (VFD) compatibility for optimized dynamic operational speed.
Heavy-Duty Bearing System
- Axial Thrust Management: Oversized radial and axial bearings paired with α balance piston and anti-reverse rotation design absorb heavy mechanical loads and extend service life
- Flanged Solenoid Valve Control: Enables quick loading and unloading to reach target temperatures via 4-stage step regulation (35%-50%-75%-100%) or continuous stepless modulation (35%-100%)
- Multi-Refrigerant Adaptability: Operates seamlessly with R22, R407C, R404A, and R507A refrigerant systems
Applications
- Process Cooling & Sub-Cooling Systems: Ideal for industrial cooling plants requiring economizer sub-cooling performance and flexible motor control
- Large Cold Storage Facilities: Designed for low-temperature food preservation hubs, distribution centers, and commercial cold rooms
- Central Air Conditioning & Chillers: Well-suited for large water-cooled and air-cooled liquid chiller plants operating under dynamic load conditions
- Chemical & Industrial Processing: Delivers stable temperature control for pharmaceutical processing and chemical fluid cooling operations
