RC2-790B-W Water Cooled Semi-Hermetic HVAC Screw Compressor

Specially engineered for central water chillers, large-scale air conditioning facilities, and industrial climate control systems, the hvac screw compressor delivers heavy-duty thermal management under continuous duty. Operating at 2950 rpm under 50Hz, it provides a high volume displacement of 791 m³/h, which increases to 952 m³/h at 60Hz. Designed for seamless integration with eco-friendly refrigerants like R134a, R407C, R404A, and R507A, this unit handles severe thermal loads in high-demand commercial structures.

Large commercial HVAC installations frequently encounter significant energy waste and thermal instability when running fixed-output units during off-peak load periods. The hvac screw compressor addresses these operational challenges with hydraulic slide valve control, supporting 4-step capacity steps (30%, 50%, 75%, 100%) and continuous stepless modulation from 25% to 100%. Adjusting compression directly to match real-time cooling loads cuts overall power draw and extends component life.

Featuring a precision 5-to-6 asymmetric rotor profile housed in an FC25 cast iron casing, this hvac screw compressor minimizes operational vibration and maintains structural tightness under severe pressure conditions. Incoming suction gas passes directly through motor channels to dissipate heat from stator windings before entering the working chamber. Built-in PTC thermistors continuously monitor winding temperatures and discharge heat, linking to electronic modules that instantly stop operation during thermal spikes or phase abnormalities.
