Hanbell RC2-510B-W Semi-Hermetic AC Screw Compressor for Water Chiller
Product Advantages
Patented 5:6 High-Efficiency Screw Rotor Profile
The RC2-510B utilizes a patented 5:6 high-efficiency asymmetric rotor profile designed specifically for modern eco-friendly refrigerants. Manufactured using precision CNC machining centers, rotor milling, and grinding equipment, each rotor assembly undergoes ZEISS 3D coordinate inspection under strict ISO 9001 process control to ensure exceptional efficiency, low operating noise, and minimal vibration.
Precise Capacity Control & Perceptive Protection Modules
Equipped with an internal slide valve actuated by pressurized oil injection, the compressor offers both step (35-50-75-100%) and stepless (35-100%) capacity modulation to match fluctuating HVAC thermal loads smoothly. Integrated PTC thermistors and motor protection modules actively monitor discharge temperatures, coil heat, phase sequence, and phase loss, safeguarding equipment life.
Double-Walled FC25 Housing & 10-Bearing Heavy-Duty Design
Built with high-strength FC25 gray cast iron in a double-casing structure with internal reinforcing ribs, the housing maintains structural stability without thermal expansion under high-pressure conditions. A combination of 10 axial and radial bearings paired with an α axial balance piston mitigates mechanical stress to deliver extended bearing longevity.
Applications
Commercial Air Conditioning & Water Chillers
Widely integrated into air-cooled liquid chillers, water-cooled central chillers, and industrial packaged AC units demanding continuous 152 HP-183 HP duty performance.
Industrial Process & Hydronic Heat Pumps
Ideal for large-scale heat pump water heaters, heat recovery systems, and factory process fluid cooling loops using R134a, R407C, or R22 refrigerants.
Low-Temperature Economized Systems
Utilizes the built-in economizer connection port to achieve extra refrigeration capacity and improved COP in demanding process applications.

Frequently Asked Questions
Q1: What is the nominal displacement of the Hanbell RC2-510B screw compressor at 50Hz and 60Hz power frequencies?
A: The RC2-510B delivers a displacement of 508 m³/hr at 50Hz (2950 RPM) and 611 m³/hr at 60Hz (3550 RPM).
Q2: How does the internal slide valve handle partial load operation in the RC2-510B?
A: The slide valve operates via differential pressure oil injection, providing either 4-step capacity control (35-50-75-100%) or continuous stepless regulation from 35% to 100%.
Q3: What quantity of refrigeration oil is required for a complete oil charge on the RC2-510B?
A: The standard lubricant oil charge for the RC2-510B compressor is 20 liters.
Q4: What motor starting options are compatible with 50Hz three-phase power grids?
A: For 50Hz operation (380V/400V/415V), the compressor supports Star-Delta and Direct-On-Line starting configurations.
Q5: How does the double-walled FC25 housing construction contribute to lower noise levels?
A: The FC25 gray cast iron casing utilizes double-wall geometry with internal ribs to dampen structural vibration, resist deformation under gas pressure, and mute acoustic noise.
