Hanbell RC2-930B-Z RC2-930B-W Semi Hermetic Screw Type Compressor for Large Cold Room

The RC2-930B features an advanced 5:6 high-efficiency screw rotor profile patented across Taiwan, the UK, the US, and China. Manufactured using high-precision CNC machining centers, rotor milling, and grinding machines, the rotor geometry undergoes strict ISO 9001 process quality controls and ZEISS 3D coordinate inspection. This design delivers maximum displacement, exceptional volumetric efficiency, low noise, and minimal structural vibration.

Engineered for continuous heavy-duty service, this semi hermetic screw type compressor combines 10 radial and axial bearings with an α axial balance piston. This balanced structural arrangement actively counteracts dynamic compression thrust forces, minimizing axial shaft movement and substantially extending overall bearing operating life.

Equipped with an internal slide valve positioned directly in the compression chamber, the RC2-930B provides dynamic load modulation to handle fluctuating system demands. Actuated by pressurized oil injection and solenoid valves with precise pressure differentials, it supports either 4-stage stepped capacity control (35%-50%-75%-100%) or continuous stepless regulation (35%-100%).

• Large Commercial Central HVAC: Designed as a primary cooling core for high-tonnage water-cooled and air-cooled liquid chillers serving airport terminals, commercial complexes, and high-rise developments.
• District Cooling Stations: Suited for heavy-duty centralized air conditioning facilities that utilize multi-compressor parallel arrangements under variable seasonal cooling loads.
• Industrial Process Refrigeration: Ideal for high-capacity liquid chilling loops in chemical, pharmaceutical, and food processing plants that demand precise part-load control.

Ruifujie brings over two decades of technical expertise and global export capability to the B2B refrigeration and HVAC marketplace. We deliver comprehensive cooling solutions—from scroll, semi-hermetic, and screw compressors to customized unit coolers and commercial cold storage systems. Our commitment to strict factory quality controls, competitive direct-from-factory pricing, and reliable lead times makes us a trusted supply chain partner for HVAC OEMs, mechanical contractors, and engineering firms worldwide.

The unit features built-in liquid injection connection ports and external oil cooler ports, enabling engineers to implement active oil cooling loops to prevent lubricant breakdown during extreme operating conditions.

By providing continuous stepless regulation down to 35% capacity, the slide valve smoothly modulates output to match part-load thermal demands without requiring complete compressor shut-off cycles.

Embedded PTC thermistors linked to an electronic protection module actively monitor motor coil temperature, discharge gas heat, phase loss, and phase sequence errors.

Standard sample units ship within 3 business days, while volume commercial manufacturing contracts are typically completed in 10 to 15 working days.
