Hanbell RC2-710B-W Refrigeration Screw Type Refrigeration Compressor
Product Advantages
Patented 5:6 High-Efficiency Screw Rotor Profile
The RC2-710B is an industrial screw type refrigeration compressor engineered with a patented 5:6 asymmetric rotor geometry designed specifically for modern eco-friendly refrigerants. Manufactured using precision CNC machining centers, rotor milling, and grinding machines, each screw rotor undergoes ZEISS 3D coordinate inspection under strict ISO 9001 process control to deliver exceptional volumetric efficiency, low operating noise, and minimal vibration.
Precise Capacity Control & Perceptive Protection Modules
Equipped with an internal slide valve actuated by pressurized oil injection, this screw type refrigeration compressor offers both step (35-50-75-100%) and stepless (35-100%) capacity modulation to match fluctuating cooling loads smoothly. Integrated PTC thermistors and motor protection modules actively monitor discharge temperatures, coil heat, phase sequence, and phase loss to ensure maximum reliability.
Direct Flange-On FC500 Oil Separator & Low Pressure Drop Demister
Featuring a direct flange-on oil separator vessel made of high-strength FC500 ductile iron, this high-performance screw type refrigeration compressor withstands high pressure differentials while maximizing oil separation. An internal low-pressure-drop demister maintains minimal refrigerant dilution in the oil sump, preserving high oil viscosity and extending total bearing service life.
Applications
Commercial Central Air Conditioning & Water Chillers
Widely integrated into large air-cooled liquid chillers, water-cooled chillers, and district cooling systems requiring continuous 208 HP to 250 HP duty cycle performance.
Industrial Refrigeration & Process Cooling
Ideal for large-scale cold storage facilities, quick-freezing plants, and chemical process cooling loops operating with R134a, R407C, or R22 refrigerants.
Large Hydronic Heat Pumps & Heat Recovery
Provides high thermal output and operating efficiency when configured in commercial heat pump water heaters and industrial heat recovery installations.

Frequently Asked Questions
Q1: What is the nominal displacement and power rating of the Hanbell RC2-710B screw compressor at 50Hz and 60Hz?
A: The RC2-710B delivers a displacement of 713 m³/hr at 208 HP on 50Hz (2950 RPM) and 858 m³/hr at 250 HP on 60Hz (3550 RPM).
Q2: How does the slide valve handle part-load operation in the RC2-710B?
A: The slide valve operates via differential pressure oil injection, enabling 4-step capacity control (35-50-75-100%) or continuous stepless regulation from 35% to 100%.
Q3: What quantity of refrigeration lubricant is required for a full oil charge?
A: The RC2-710B compressor requires a standard oil charge of 28 liters.
Q4: What starting methods are supported by the integrated motor?
A: The motor supports Star-Delta, Part-Winding Start (PWS), and Direct-On-Line (DOL) starting configurations depending on voltage and frequency requirements.
Q5: How does the economizer port enhance performance in low-temperature refrigeration applications?
A: Connecting a middle-pressure economizer to the designated port increases system subcooling and gas mass flow, significantly boosting refrigeration capacity and seasonal COP under high pressure ratios.
