Hanbell RC2-550B-Z RC2-550B-W 195HP Semi Hermetic Screw Compressor for Industrial Chiller

Multinational Patents of High-Efficiency Screw Rotors
The RC2-550B features an advanced 5:6 high-efficiency screw rotor profile patented in Taiwan, the UK, the US, and China. Engineered specifically for modern refrigerant characteristics, these rotors are manufactured using precision CNC machining centers, rotor milling, and grinding equipment under strict ISO 9001 process controls. Verified by ZEISS 3D coordinate measuring machines, the rotor geometry delivers high displacement, maximum volumetric efficiency, low noise, and minimal operation vibration.

Long Life Bearings & High Reliability
Engineered to withstand heavy dynamic loads, the compressor incorporates a combination of 10 axial and radial bearings paired with an α axial balance piston. This design effectively counteracts compression thrust forces, minimizing mechanical shaft displacement and significantly extending total bearing operational life.

Adaptable with Additional Cooling
Designed for ultimate versatility in varying ambient and heavy-duty conditions, the unit is built with dedicated auxiliary connection ports. It features liquid injection ports located at the motor casing and compression chamber, external oil cooler ports, and a middle-pressure economizer port to boost part-load efficiency.
