RC2-550B-W High-Efficiency AC Screw Compressor For Chiller

Engineered specifically for large commercial HVAC installations, central water chillers, and air-cooled liquid chilling plants, the RC2-550B-W ac screw compressor delivers a high volumetric displacement of 550 m³/hr at 50Hz with 165HP nominal output. Utilizing a patented 5:6 asymmetric lobe rotor profile machined to micron-level tolerances, the compressor maintains continuous smooth gas suction and compression. This continuous rotary displacement maximizes energy efficiency while eliminating the pressure pulsation and mechanical wear associated with reciprocating machinery.

To meet strict building energy efficiency standards under partial cooling loads, the compressor incorporates a dual hydraulic slide valve system for 4-step capacity regulation or continuous stepless modulation. Combined with five available Volume Index ratios and an integrated economizer sub-cooling port, the unit adapts dynamically to changing ambient weather conditions without efficiency degradation.

Designed for noise-sensitive commercial building environments, the housing is cast from high-density FC25 gray cast iron with internal structural reinforcement walls. This heavy-duty frame absorbs mechanical resonance, while dynamic balance alignment of the 5:6 screw rotors minimizes vibration transmission into chiller frames and building piping. An internal 20-liter oil sump and ductile iron oil separator preserve lubrication film strength without requiring external oil pumps.
