06NW2209S7EA-A00 75HP Water Cooled Refrigeration Screw Compressor for HVAC

This industrial screw compressor HVAC unit is engineered for commercial water-cooled liquid chillers, delivering optimized thermal efficiency, quiet operation, and extended service life.

Commercial water-cooled liquid chillers operate most efficiently at moderate compression ratios. Built with an internal Vi 2.5 discharge profile and an integrated 1-3/8 in economizer circuit, this industrial screw compressor HVAC maximizes coefficient of performance (COP) without over-compressing refrigerant gas. By delivering enhanced liquid subcooling and flexible 3-step unloading (100%-66%-33%), it significantly reduces seasonal kilowatt-hour consumption in central building systems.

Noise compliance in commercial office buildings and institutional facilities demands smooth mechanical execution. This high-capacity screw compressor HVAC integrates precision-balanced twin screw rotors, built-in discharge silencing mufflers, and optimal internal fluid passage designs. The result is continuous, low-vibration operation that lowers acoustic dampening requirements and protects surrounding pipe structures from resonant stress.

Heavy mechanical stress during peak cooling cycles requires superior internal protection to avoid unexpected system downtime. Engineered with heavy-duty SKF/NSK rolling element bearings, an internal oil filtration system, and an automatic reverse-rotation check valve, this screw compressor HVAC minimizes wear on critical moving parts. Combined with NTC winding thermistors and a built-in safety relief valve, it maintains continuous duty while extending maintenance intervals.
