The RC2-930B screw refrigeration compressor is engineered for high-tonnage industrial chilling, commercial refrigeration, and severe-duty HVAC applications. Powered by a twin-shaft rotary displacement design, it delivers continuous volumetric output and operational stability under heavy thermal loads.

Patented 5:6 Screw Rotor Geometry & High-Efficiency Motor
Featuring precision CNC-machined 5:6 asymmetric screw rotors, this screw refrigeration compressor minimizes internal gas bypass and mechanical friction. Driven by an integrated 3-phase, 2-pole squirrel-cage induction motor cooled directly by suction gas, the unit maintains high energy efficiency across both 50Hz and 60Hz power supplies.

Adaptive Load Control & Multi-Refrigerant Versatility
To match dynamic cooling loads and optimize energy consumption during part-load conditions, 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 screw refrigeration compressor integrates easily into diverse cooling plant designs.

• High-Density Gray Iron Housing: Cast from FC25 gray cast iron with inner structural reinforcement ribs to absorb operational vibration and suppress noise.
• Flange-On Oil Separator: Constructed from high-strength FC500 ductile iron to manage high working pressures while maintaining low pressure drop and high oil separation efficiency.
• 10-Bearing Heavy-Duty Assembly: Combines radial and axial bearings with an alpha balance piston to absorb axial thrust forces and extend service life.
• Integrated Electronic Safeguards: Standard PTC thermistor modules continuously monitor motor coil heat, discharge gas temperatures, phase loss, and phase sequence errors.

• Large Industrial Cold Storage & Logistics: Ideal for large low-temperature cold storage warehouses, agricultural logistics parks, and food preservation distribution centers.
• Central Liquid Chiller Plants: Designed for high-capacity air-cooled and water-cooled liquid chiller plants operating under variable load conditions.
• Blast Freezing & Food Processing: Delivers high continuous displacement for quick-freezing tunnels, meat processing facilities, and marine refrigeration plants.
• Industrial Process Chilling: Provides precise, reliable temperature control for heavy chemical processing, pharmaceutical lines, and manufacturing fluid cooling.
