Engineered specifically for central air-cooled liquid chillers and industrial HVAC process systems, the 06NA2174S7EA-A00 semi-hermetic HVAC screw compressor incorporates Carlyle's patented twin-rotor geometry driven by an integrated speed-multiplying gear drive. Designed for eco-friendly R134a refrigerant, its air-cooled volume ratio (Vi) ensures high volumetric efficiency, stable gas compression, and reduced power consumption across broad commercial cooling envelopes.
Featuring built-in economizer circuit compatibility, this model allows system designers to implement liquid subcooling before entering the evaporator. By utilizing flash-gas subcooling via a dedicated economizer connection, the compressor boosts net refrigeration capacity and improves total coefficient of performance (COP), especially during peak summer condensing conditions.
To ensure continuous operation under demanding load variations, the compressor is fitted with precision SKF/NSK rolling thrust bearings that withstand high pressure differentials. Internal mechanical protections include an anti-reverse rotation check valve to protect rotors during system shutdowns, an integrated oil filter, and a discharge muffler that minimizes gas pulsation noise. The high-efficiency motor supports Star-Delta (Y-Δ) starting to suppress electrical grid inrush current during startup.

Ruifujie is a specialized B2B manufacturer and exporter of commercial and industrial refrigeration equipment with over two decades of international trade experience. Our comprehensive product portfolio includes semi-hermetic screw compressors, reciprocating units, scroll compressors, water-chiller components, and custom-built multi-compressor rack systems. Partnering with mechanical contractors, HVAC engineers, and system builders across Europe, the Americas, and the Middle East, Ruifujie offers direct factory pricing, strict quality control standards, and responsive OEM/ODM technical support.
Connecting an economizer subcools the liquid refrigerant before the expansion valve, significantly boosting cooling capacity and energy efficiency without increasing compressor displacement.
The built-in reverse-rotation check valve prevents high-pressure discharge vapor from expanding back into the suction line, protecting the twin rotors and internal gears from reverse rotation wear.
Yes, the 06NA2174S7EA-A00 is engineered to operate efficiently under both 400V/50Hz and 460V/60Hz supply voltages.
In-stock standard units ship within 5 to 7 business days, while bulk orders or custom voltage specifications ship within 15 to 20 days.
Units are anchored onto heavy wooden skids, wrapped in anti-moisture barrier packaging, and enclosed in export-grade plywood crates built for safe sea and air transport.
