06NA2146S7NA-A00 75HP R134a AC Screw Refrigeration Compressor
Product Advantages
Patented Rotor Design & High-Efficiency Geometry
Equipped with a patented profile rotor geometry, this screw refrigeration compressor delivers optimized volumetric efficiency and reduced internal leakage gaps. The built-in speed-increasing gear enhances rotor velocity, driving superior performance across commercial HVAC and industrial chiller applications.
Three-Stage Capacity Control (100%-66%-33%)
Featuring a dynamic load matching mechanism controlled via dual solenoid valves, this screw refrigeration compressor supports three-stage unloading (100%, 66%, and 33%). This allows precise capacity regulation under varying thermal loads, reducing operational energy costs and ensuring system stability.
Robust Mechanical Engineering & Heavy-Duty Bearings
Built with high-precision SKF or NSK rolling bearings and reinforced thrust bearings, the mechanical assembly handles continuous axial loads in heavy-duty screw refrigeration compressor installations. The integrated internal check valve prevents reverse rotation at shutdown, while an internal oil filter, safety valve, and muffler minimize operational noise and protect internal components against contamination.
High-Strength Motor with Integrated Thermal Protection
Designed for universal voltage adaptability, the motor supports both Star-Delta (Y-Δ) and Direct-On-Line (DOL) startup modes. It features an integrated NTC thermistor sensor for direct winding protection, high-grade suction strainers, and precise slide fits to maintain long-term electrical reliability.
Eco-Friendly R134a Compatibility & Economizer Readiness
Engineered specifically for eco-friendly R134a refrigerant, the unit operates efficiently in both air-cooled and water-cooled systems. Supporting economizer integration, it maximizes cooling output across various working conditions with full factory reliability.
