The RC2-100B screw refrigeration compressor is engineered to deliver reliable cooling performance and high operating efficiency across commercial and industrial systems. Designed with an optimized two-shaft rotary displacement mechanism, it provides stable operation under demanding thermal conditions.
Advanced Features
Advanced 5:6 Rotor Profile & High-Efficiency Motor
Featuring patented 5:6 asymmetric screw rotors manufactured via precision CNC machining, this screw refrigeration compressor minimizes mechanical friction and suction losses. Driven by a 3-phase, 2-pole squirrel-cage induction motor cooled by suction refrigerant gas, the unit ensures maximum operating efficiency across both 50Hz and 60Hz power supplies.
Flexible Capacity Control & Multi-Refrigerant Adaptability
To match changing cooling loads while optimizing power consumption, the screw refrigeration compressor offers dual capacity control options: 3-stage step control (33% - 66% - 100%) or continuous stepless adjustment (33% - 100%). The system is fully compatible with R22, R407C, R404A, and R507A refrigerants, making it highly adaptable for various system designs.
Double-Walled Rotor Casing: Built from FC25 gray cast iron with inner ribbing to enhance rigidity and suppress operational noise.
Direct Flange-On Oil Separator: Constructed from ductile FC500 iron to handle high pressure, ensure low pressure drop, and maintain optimal oil viscosity.
Long-Life Bearing Assembly: Utilizes a combination of 10 axial and radial bearings with an axial balance piston to ensure smooth shaft stability and extended service life.
Perceptive Protection System: Integrated PTC thermistors and protection modules monitor discharge gas temperature, motor coil heat, phase sequence, and phase loss.
Applications
Commercial Cold Storage: Suitable for medium and low-temperature cold rooms, walk-in freezers, and logistics cold storage centers.
Industrial Chiller Systems: Designed for liquid chillers and process cooling plants requiring continuous, stable cooling output.
Food Processing & Freezing: Ideal for food freezing tunnels, beverage processing lines, and blast freezing equipment.
HVAC & Commercial Air Conditioning: Suitable for centralized commercial air conditioning systems requiring precise part-load capacity control.
