06NW2174S7EA-A00 Screw AC Compressor

The 06NW2174S7EA-A00 is a 60 HP commercial twin screw ac compressor designed for high-efficiency water-cooled chillers, large HVAC plants, and industrial process cooling skids. Optimized for lower pressure differential operating conditions with eco-friendly R134a refrigerant, this unit integrates an economizer port to deliver vapor subcooling.

Built for continuous operation in indoor mechanical rooms, the 06NW2174S7EA-A00 utilizes Carlyle's patented twin-screw rotor profile to achieve uniform, pulse-free gas discharge with minimal acoustic transmission. Heavy-duty SKF or NSK rolling bearings combined with robust axial thrust protection absorb heavy mechanical stress to extend routine maintenance intervals. The unit includes an internal check valve to prevent rotor reverse rotation during shutdown, an internal pressure relief valve, a fine-mesh oil filter, and a built-in discharge muffler.

To adapt to fluctuating building cooling demands, this screw ac compressor employs a dual-solenoid 3-stage capacity control mechanism,from 100%, 66% to 33%. This multi-step modulation reduces short-cycling and optimizes part-load power draw. Driven by a high-efficiency motor with integrated NTC thermistor thermal protection, the compressor supports both Star-Delta and Direct-On-Line starting across global electrical configurations.
