The RC2-830B semi hermetic screw type compressor is engineered for high-tonnage industrial chilling, heavy-duty commercial refrigeration, and large-scale central HVAC systems. Driven by a twin-shaft rotary displacement mechanism, it provides continuous volumetric output and mechanical reliability under demanding operational loads.
Featuring precision CNC-machined 5:6 asymmetric screw rotors, this semi hermetic screw type compressor minimizes internal gas recirculation and mechanical drag. Driven by an integrated 3-phase, 2-pole squirrel-cage induction motor cooled directly by suction refrigerant gas, the unit delivers optimum energy efficiency across both 50Hz and 60Hz power configurations.
To align energy consumption with dynamic cooling demands, an internal hydraulic slide valve provides 4-stage step capacity regulation (35% - 50% - 75% - 100%) as well as continuous stepless modulation (35% - 100%). Compatible with R22, R407C, R404A, and R507A refrigerants, this semi hermetic screw type compressor integrates smoothly into diverse cooling plant architectures.
