06NA2250S7EA-A00 120HP Air Cooled Refrgeration Rooftop AC Screw Compressor

Managing utility budgets in high-capacity central air conditioning and process chilling demands superior energy efficiency. Featuring a dedicated 1-3/8 in economizer interface, this high-performance AC screw compressor significantly increases liquid subcooling, boosting system cooling capacity without a proportional increase in power draw. Combined with a 3-step capacity modulation system (100%-66%-33%), it dynamically adjusts to variable thermal loads, slashing peak electrical charges for commercial facilities.

Frequent start-stop cycles and heavy thermal loads can compromise internal mechanics in industrial chillers. Engineered with patented rotor profiles, heavy-duty SKF/NSK bearings, and an internal check valve, this AC screw compressor prevents rotor reverse rotation during shutdown and reduces gas bypass leakage. An integrated oil filter, discharge muffler, and internal safety relief valve ensure smooth, low-vibration operation and extended service intervals.

Adapting large-scale HVAC systems to evolving global environmental standards and power grids requires adaptable equipment. Operating on eco-friendly R134a refrigerant with UL, CE, and ISO 9002 certifications, this AC screw compressor includes high-efficiency motor windings with integrated NTC thermal sensors. Supporting dual-voltage operation, it provides a direct drop-in replacement for major commercial air-cooled liquid chillers.
