Hanbell RC2-310B-Z RC2-310B-W Refrigeration Screw Air Conditioning Compressor
Product Description
Patented 5:6 Screw Rotor Geometry
The RC2-310B utilizes a high-precision 5:6 patented screw rotor profile machined using advanced CNC milling and gear grinding equipment. By completely eliminating wearing components such as pistons, wrist pins, and suction/discharge valve plates, this high-performance screw air conditioning compressor delivers exceptionally smooth operation, low running noise, and minimized vibration.
High-Efficiency Motor & Vapor Cooling
Powered by a 3-phase, 2-pole squirrel-cage induction motor built with premium low-loss core steel and F-class insulation. The motor is continuously cooled by suction refrigerant gas directed through dedicated internal slots and guide vanes, maintaining high operational efficiency across varying B2B HVAC workloads.
Heavy-Duty Bearing Assembly & Load Balance
Constructed with a double-walled FC25 gray cast iron housing engineered with internal reinforcement ribs to prevent thermal expansion under high operating pressures. Internal mechanical endurance is supported by a robust combination of 10 radial and axial bearings paired with an α balance piston to counteract dynamic axial thrust loads and extend bearing service life.
Flexible Capacity Control & Economizer Ports
Engineered to handle variable cooling demands, this screw air conditioning compressor provides precise load modulation through an internal hydraulic slide valve, supporting 4-stage step control (35%-50%-75%-100%) or continuous stepless regulation (35%-100%). Built-in auxiliary ports accommodate liquid injection, external oil cooling, and economizer sub-cooler circuits.
Integrated Oil Management & Electronic Protection
Oil Separation: Includes a direct flange-on FC500 ductile iron oil separator to maintain high lubricant viscosity and minimize refrigerant oil carryover.
Motor Protection: Equipped with embedded PTC thermistors and a motor protection module monitoring discharge gas heat, coil temperatures, phase loss, and phase sequence.
System Accessories: Compatible with oil level switches, differential pressure switches, and safety pressure relief valves.
Application Areas
Commercial Central HVAC: Ideal for large water-cooled and air-cooled liquid chillers serving office buildings, commercial complexes, and centralized screw air conditioning compressor plants.
Process Air Conditioning & Cooling: Suitable for precision environmental control in cleanrooms, data centers, and industrial manufacturing plants.
Cold Storage Logistics: Designed for medium-temperature refrigeration systems and agricultural precooling facilities requiring dynamic capacity modulation.
