06NA2209S7NA-A00 90HP Air Cooled Semi Hermetic Screw Compressor

This high-efficiency semi hermetic screw compressor delivers reliable performance for large commercial HVAC and fluid chilling applications with advanced capacity modulation and robust construction.

Equipped with a 3-step capacity modulation system (100%-66%-33%) driven by dual solenoid valves, this compressor dynamically matches changing cooling demands to reduce power consumption during off-peak hours, lowering demand charges and long-term operating expenses.

Built with patented high-precision rotor geometry, heavy-duty SKF/NSK bearings, and an internal check valve, this compressor eliminates reverse rotation at shutdown and minimizes gas bypass leakage. An integrated oil filter, safety relief valve, and discharge muffler ensure smooth, quiet, and continuous performance under severe duty conditions.

Certified under UL, CE, and ISO 9002 standards, this compressor operates efficiently on eco-friendly R134a refrigerant. Featuring high-efficiency motor windings with integrated NTC thermal protection and dual-voltage support (400V/50Hz, 460V/60Hz), it offers a seamless replacement solution for air-cooled liquid chillers worldwide.
