06NW2209S7EA-A00 Industrial HVAC Screw Compressor for Air Conditioning
Product Advantages
High-Displacement Volumetric Output for Commercial Chillers
Engineered with a high-efficiency patented profile rotor geometry and internal speed-increasing gear acceleration, this HVAC screw compressor delivers an outstanding volumetric displacement of 209 CFM. Designed specifically for high-tonnage water-cooled central chillers, it maximizes gas flow stability while drastically reducing internal blow-by losses.
Integrated Economizer Circuit for Peak Seasonal Efficiency
Featuring a dedicated 1-3/8 in factory economizer interface, this 75 HP compressor supports advanced liquid subcooling. Incorporating an economizer circuit significantly increases system refrigeration capacity and boosts total Coefficient of Performance (COP) during peak summer cooling demands.
Dynamic Three-Step Energy Control
Driven by dual solenoid valve actuators, the integrated unloading mechanism provides precise three-stage capacity control (100%, 66%, and 33%). This variable load matching enables central air conditioning systems to maintain tight ambient temperature regulation while optimizing power consumption under partial loads.
Heavy-Duty Mechanical Drive & Integrated Noise Suppression
Equipped with heavy-duty SKF/NSK rolling bearings and reinforced axial thrust bearings, the mechanical drive reliably withstands severe continuous pressure differentials. An integrated discharge muffler dampens gas pulsation noise, while internal non-return check valves prevent reverse rotation upon shutdown.
High-Output 75 HP Motor with Comprehensive Thermal Protection
Built to interface with global industrial power grids across 50Hz and 60Hz frequencies, the 75 HP motor supports both Star-Delta and Direct-On-Line (DOL) starting modes. Embedded NTC thermistor sensors continuously monitor winding temperatures to prevent electrical thermal damage.

Frequently Asked Questions
Q1: What makes the 06NW2209S7EA-A00 suitable for large commercial central HVAC chillers?
A1: Delivering 75 HP output with 209 CFM displacement, it provides the volumetric throughput required for heavy-duty water-cooled chillers operating under intensive cooling schedules.
Q2: How does the active economizer port improve chiller operating economy?
A2: Connecting an economizer loop to the 1-3/8 in port feeds subcooled liquid into the compression chamber, boosting overall cooling tonnage and improving seasonal COP without proportional energy consumption increases.
Q3: Can this model accommodate different global industrial electrical grids?
A3: Yes, the motor winding supports multi-voltage operation across 60Hz and 50Hz utility standards.
Q4: What is the lead time for sample units and bulk project shipments?
A4: Single stock units and replacement samples dispatch within 3 business days, while volume OEM order fulfillment is completed within 10 to 15 business days.
Q5: What anti-damage measures are taken for ocean container freight?
A5: Each compressor undergoes pressure testing, is charged with dry holding gas, and is vacuum-sealed in a fully reinforced wooden crate to guard against sea salt corrosion and transit vibration.
