The RC2-340B semi hermetic screw type compressor is designed for high-capacity commercial and industrial cooling applications. Powered by a twin-shaft rotary displacement mechanism, it provides continuous volumetric efficiency and reliable performance under demanding operational conditions.

Featuring precision CNC-machined 5:6 asymmetric screw rotors, this semi hermetic screw type compressor minimizes internal gas recirculation and mechanical friction loss. Its integrated 3-phase, 2-pole squirrel-cage induction motor is cooled directly by suction gas, maintaining high energy efficiency across 50Hz and 60Hz power supplies.

To adapt to fluctuating cooling loads and reduce power consumption during part-load operation, the compressor includes an internal hydraulic slide valve. It supports 4-stage step capacity control (35% - 50% - 75% - 100%) and continuous stepless modulation (35% - 100%). Designed for broad applicability, this semi hermetic screw type compressor is compatible with R22, R407C, R404A, and R507A refrigerants.

• Double-Walled Cast Iron Housing: Constructed from FC25 gray cast iron with inner reinforcement ribs to suppress operational noise and eliminate housing expansion under high pressure.
• Flange-On Oil Separator: Cast from high-strength FC500 ductile iron to handle high pressure while ensuring low pressure drop and high oil separation efficiency.
• 10-Bearing Heavy-Duty Assembly: Combines 10 radial and axial bearings with an alpha balance piston to counteract thrust forces and maximize bearing service life.
• Integrated Electronic Protections: Standard PTC thermistor modules continuously monitor motor coil heat, discharge gas temperatures, phase loss, and phase sequence errors.

• Commercial & Industrial Liquid Chillers: Ideal for large water-cooled and air-cooled chiller plants requiring flexible part-load capacity control.
• Commercial Cold Storage: Well-suited for medium- and low-temperature cold storage warehouses, food processing units, and distribution hubs.
• Central Air Conditioning Systems: Provides reliable cooling for commercial building HVAC installations, shopping malls, and large facilities.
• Industrial Process Cooling: Delivers continuous cooling performance for chemical, pharmaceutical, and manufacturing processes.
