06NW2209S7EA-A00 75HP Water Cooled Refrigeration Screw Compressor for HVAC
Product Overview
This industrial screw compressor HVAC unit is engineered for commercial water-cooled liquid chillers, delivering optimized thermal efficiency, quiet operation, and extended service life.
Optimized Thermal Efficiency for Chilling
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.
Quiet Performance and Low Vibration
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.
Extended Lifespan with Built-in Protections
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.

Frequently Asked Questions
Q1: What are the primary displacement figures for the 06NW2209S7EA-A00 compressor?
A1: The 06NW2209S7EA-A00 features a displacement of 290 m³/h at 50Hz (209 CFM at 60Hz).
Q2: How does the combination of Vi 2.5 and an economizer circuit benefit water-cooled HVAC systems?
A2: The Vi 2.5 profile is matched specifically to water-cooled pressure ratios, while the economizer subcools liquid refrigerant to increase cooling output and operating COP without adding motor workload.
Q3: What internal lubrication and protective devices are engineered into this 75HP frame?
A3: The compressor includes an internal oil filter, an oil pump system, an anti-reverse rotation check valve, a discharge muffler, an internal safety relief valve, and NTC motor thermistors.
Q4: What is the delivery lead time for samples and volume orders?
A4: In-stock sample orders are dispatched within 3 business days, while standard complete production orders are fulfilled within 10 to 15 working days.
Q5: Do you support custom branding, private labeling, and multilingual nameplates?
A5: Yes, Ruifujie provides comprehensive OEM services supporting custom company logos and multilingual nameplate customization for global distributors.
