RC2-830B-Z Air Cooling Semi-Hermetic Refrigeration Screw Compressor

Engineered for industrial chillers, food freezing systems, and large commercial cold storage, the RC2-830B refrigeration screw compressor provides robust gas handling for heavy cooling duties. Operating with a 50Hz displacement of 825 m³/h and 993 m³/h at 60Hz, this semi-hermetic unit works with refrigerants such as R134a, R22, R407C, R404A, and R507A. It delivers reliable mass flow to handle peak thermal loads in process cooling facilities.

Industrial refrigeration setups often waste power when operating at fixed displacement during off-peak hours, increasing operating costs and equipment wear. The RC2-830B refrigeration screw compressor addresses this issue using internal slide valve mechanisms that provide 4-step capacity control (35%, 50%, 75%, 100%) and continuous stepless modulation from 35% to 100%. Matching output directly to system heat loads reduces energy consumption while maintaining stable target temperatures.

Built around a patented 5-to-6 lobe rotor profile and an FC25 cast iron casing, this refrigeration screw compressor delivers high volumetric efficiency with low running noise. An integrated alpha balance piston counters axial thrust forces on oversized bearings, while Class F motor insulation and suction gas guide vanes ensure low winding temperatures. The unit also supports economizer sub-cooling circuits to boost cooling capacity during partial and full load conditions.
