Product Description
06NW2250S7NA-A00 75HP R134a Refrigeration AC Screw Compressor for Chiller
Product Overview
This high-efficiency AC screw compressor is engineered for commercial water-cooled chillers, delivering reliable performance and energy savings.
Precision Load Management
Featuring a 3-step capacity control system (100%-66%-33%) driven by dual solenoid valves, this compressor dynamically adjusts output to match cooling demands. By reducing power consumption during off-peak hours, it lowers peak demand charges and significantly cuts long-term operating expenses.
Robust Construction for Continuous Operation
Engineered with patented rotor profiles, heavy-duty SKF/NSK bearings, and an internal check valve, this compressor eliminates rotor reverse rotation during shutdown and minimizes internal gas bypass leakage. An integrated oil filter, discharge muffler, and internal safety relief valve ensure smooth, whisper-quiet continuous performance.
Environmental Compliance and Versatility
Certified under UL, CE, and ISO 9002 standards, this compressor is optimized for eco-friendly R134a refrigerant. Featuring high-efficiency motor windings with integrated NTC thermal protection and dual-voltage support (400V/50Hz, 460V/60Hz), it provides a seamless replacement solution for commercial liquid chillers.
