06NA2174S7EA-A00 90HP Industrial Refrigeration HVAC Screw Compressor

High-performance HVAC screw compressor designed for industrial refrigeration and process cooling applications with superior efficiency and reliability.

Managing utility budgets in high-capacity HVAC and process cooling applications requires superior part-load efficiency. Designed with a dedicated 1-3/8 in economizer port, this high-performance HVAC screw compressor boosts system subcooling and cooling capacity without proportionally increasing power consumption. Combined with a 3-step capacity control system (100%-66%-33%), it dynamically matches variable thermal loads, lowering operating expenses and reducing energy waste across large commercial facilities.

Frequent operational stops and heavy thermal cycles can cause severe wear on rotor bearings and internal seals. Built with patented rotor geometry, premium SKF/NSK rolling bearings, and an internal check valve, this heavy-duty HVAC screw compressor eliminates rotor reverse rotation at shutdown and minimizes internal pressure leakage. An integrated oil filter, discharge muffler, and internal safety relief valve ensure smooth, continuous duty while extending routine maintenance intervals.

Adapting large-scale chiller equipment to global power standards and strict environmental codes requires versatile machinery. Certified under UL, CE, and ISO 9002 standards, this HVAC screw compressor operates efficiently on eco-friendly R134a refrigerant. Featuring high-efficiency motor windings with integrated NTC thermal protection and dual-voltage support, it provides a direct drop-in replacement solution for major commercial air-cooled liquid chillers.
