Hanbell RC2-930B-Z RC2-930B-W R134a Semi-Hermetic Screw Refrigeration Compressor

• Patented 5:6 High-Efficiency Screw Rotor Profile - Engineered with patented 5:6 asymmetric rotor geometry for high volumetric efficiency with modern refrigerants. Manufactured using precision CNC equipment with ISO 9001 process controls to ensure low noise, minimal vibration, and maximum thermal performance.
• Precise Capacity Control & Protection Modules - Features internal slide valve actuated by differential oil pressure supporting 4-step (35-50-75-100%) and continuous stepless (35-100%) capacity modulation. Integrated PTC thermistors and motor protection modules monitor discharge gas temperature, motor coil heat, phase sequence, and phase loss.
• Premium High-Efficiency Motor & Suction Cooling - Built with premium low-loss core steel and dedicated cooling channels that route cool suction gas directly across windings before compression, preserving electrical efficiency and insulation life during heavy full-load cycles.

• Commercial Central Air Conditioning & Large Chillers - Ideal for high-capacity air-cooled liquid chillers, water-cooled central chillers, and district cooling loops requiring 278 HP to 334 HP duty cycles.
• Industrial Cold Storage & Food Processing - Provides steady low-temperature cooling for commercial food processing, blast freezing, and cold storage facilities using R134a, R407C, or R22 refrigerants.
• Large Hydronic Heat Pumps & Heat Recovery - Delivers substantial heat output and operating efficiency in commercial heat pump water heaters and industrial waste heat recovery systems.
