Hanbell RC2-260B-Z RC2-260B-W High Performance Semi Hermetic Screw AC Compressor
Product Overview
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.
Key Features
Patented 5:6 Screw Rotor Profile & High-Efficiency Motor
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.
Versatile Load Control & Multi-Refrigerant Operation
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.
Durable Housing & Complete Protection Suite
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.
Applications
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.
