Hanbell RC2-140B-Z RC2-140B-W R134a R22 Refrigeration HVAC Screw Compressor

Patented 5:6 Screw Rotor Profile
The RC2-140B incorporates an advanced 5:6 patented screw rotor profile manufactured using high-precision CNC gear grinding equipment. By eliminating reciprocating parts such as pistons, rings, and valve plates, this design reduces internal friction and mechanical wear, allowing the unit to perform as a low-noise, low-vibration HVAC screw compressor for continuous commercial operations.

High-Efficiency Motor & Vapor Cooling
Powered by a 3-phase, 2-pole squirrel-cage induction motor constructed from premium low-loss core steel. The motor is directly cooled by suction refrigerant gas guided through dedicated internal slots and guide vanes, maintaining consistent motor efficiency even under heavy system loads.

Heavy-Duty Housing & Extended Bearing Life
The compressor housing is cast from high-strength FC25 gray iron with a double-walled inner-rib structure to prevent expansion during high-pressure operation. Inside, a combination of 10 axial and radial bearings paired with an axial balance piston minimizes axial shaft displacement, significantly extending overall bearing service life.

Flexible Capacity Control & System Integration
As a highly adaptable HVAC screw compressor, it offers flexible output adjustment options—either stepped control (33%-66%-100%) or stepless control (33%-100%) via an internal hydraulic slide valve. It also features dedicated connection ports for liquid injection, external oil coolers, and economizer circuits to optimize part-load efficiency.

• Oil Separation: Includes a direct flange-on FC500 ductile iron oil separator with multi-stage separation to reduce oil carryover and maintain lubricant viscosity.
• Protection Features: Equipped with PTC thermistors and an electronic motor protection module to continuously monitor discharge temperatures, motor coil heat, phase sequence, and phase loss.
• Optional Controls: Compatible with oil level switches, pressure differential switches, and pressure relief valves.

• Commercial Central HVAC: Suitable for commercial water chillers, packaged air conditioning units, and centralized HVAC systems requiring a reliable HVAC screw compressor for continuous thermal control.
• Process Cooling Systems: Designed for industrial fluid chillers and process cooling loops where variable load matching and part-load efficiency are critical.
• Commercial Cold Storage: Ideal for medium-temperature refrigeration plants, cold room storage facilities, and agricultural precooling installations.
