RC2-710B-W Semi Hermetic Screw Type Compressor For Cold Room

Tailored for commercial fluid chillers, process cooling plant setups, and medium-temperature cold storage facilities, the RC2-580B semi hermetic screw type compressor supplies continuous cooling output across demanding operational cycles. Operating at a rated displacement of 583 m³/h (50Hz) and 702 m³/h (60Hz), this refrigeration power unit supports common industrial refrigerants such as R134a, R407C, R404A, and R507A. Its heavy-duty construction delivers steady gas circulation and reliable thermal control, addressing high load requirements in large-scale air conditioning and food processing systems.

Refrigeration facilities frequently face energy waste and mechanical strain caused by running fixed-displacement units under fluctuating cooling demands. The RC2-580B semi hermetic screw type compressor mitigates these operational issues through built-in hydraulic slider mechanisms, enabling 4-step capacity control alongside continuous stepless output modulation. By continuously aligning displacement with live system heat loads, this design reduces peak power consumption, cuts operating expenses, and minimizes valve wear during partial-load hours.

Constructed with a high-strength FC25 cast iron body and a precision 5-to-6 asymmetric rotor profile, this semi hermetic screw type compressor resists physical casing expansion under elevated operating pressures. Suction gas is routed across internal motor channels to cool stator windings directly before entering the compression chamber, maintaining stable motor coil temperatures. Integrated PTC thermistors and electronic protection modules constantly track winding heat, discharge gas temperatures, and phase sequence to prevent unexpected electrical burnouts.
