• Patented Rotor Geometry & High Displacement Output
  Engineered with high-efficiency patented profile rotor geometry, this AC screw compressor minimizes internal clearance leaks to deliver superior volumetric performance. Featuring an internal speed-increasing gear, it generates a high displacement of 209 CFM tailored for commercial HVAC systems and industrial chillers.
• Three-Stage Capacity Control
  Utilizing dual solenoid valve controls, this heavy-duty AC screw compressor supports three-step load regulation at 100%, 66%, and 33% capacity steps. This flexible load-matching capability optimizes energy consumption during partial-load conditions and maintains stable target temperatures under fluctuating system loads.
• Heavy-Duty Mechanical Engineering & Built-In Safeguards
  Built with high-precision SKF or NSK rolling bearings and reinforced thrust bearings, this AC screw compressor easily withstands continuous axial loads. An internal check valve prevents shutdown rotor reversal, while an integrated safety valve, oil filter, and muffler protect internal mechanisms and suppress operational noise.
• High-Efficiency Motor with Winding Thermal Protection
  Designed for global industrial power standards, the 90 HP motor supports Star-Delta conversion and Direct-On-Line starting modes. Integrated NTC thermistors offer direct thermal protection across all motor windings, while fine suction strainers ensure clean gas flow.
• Eco-Friendly R134a Compatibility & Factory Reliability
  Optimized for eco-friendly R134a refrigerant, the unit excels in air-cooled and water-cooled refrigeration systems. Every unit undergoes 100% factory run testing and a 33-point quality inspection to ensure exceptional reliability, low vibration, and quiet operation.
