06NW2250S7EA-A00 85HP Semi Hermetic Screw Compressor for Industrial AC Unit
Enhanced Efficiency with Economizer Technology
Operating large-scale water-cooled chiller systems requires maximum efficiency during partial-load conditions. This high-performance semi hermetic screw compressor features a dedicated 1-3/8 inch economizer interface that significantly increases liquid refrigerant subcooling, raising system cooling output without increasing power input.
Paired with a 3-step capacity modulation system (100%-66%-33%), it dynamically adapts to changing thermal demands, effectively reducing peak electrical utility charges.
High Reliability for Demanding Applications
Engineered to withstand heavy thermal stresses and frequent start-stop cycles in commercial chillers, this compressor features:
- Patented rotor profiles for optimal performance
- Heavy-duty SKF/NSK bearings for extended service life
- Internal check valve to prevent rotor reverse rotation at shutdown
- Minimized gas bypass leakage for improved efficiency
- Integrated oil filter, discharge muffler, and internal safety relief valve
Environmental Compliance and Global Compatibility
Meeting strict international environmental regulations, this compressor operates on eco-friendly R134a refrigerant and carries UL, CE, and ISO 9002 certifications. It features high-efficiency motor windings with integrated NTC thermal protection and supports dual-voltage operation, making it an ideal direct drop-in replacement for water-cooled liquid chillers worldwide.

Frequently Asked Questions
Q1: What are the exact displacement figures and port dimensions for the 06NW2250S7EA-A00?
A1: The 06NW2250S7EA-A00 yields a displacement of 347 m³/h at 50Hz (250 CFM at 60Hz).
Q2: How does the water-cooled Vi 2.5 ratio combined with an economizer enhance efficiency?
A2: The Vi 2.5 discharge profile is engineered specifically for lower pressure ratio water-cooled applications, while the economizer subcools liquid refrigerant to increase total cooling capacity and COP without raising motor power input.
Q3: What internal protective components are integrated into this 85HP compressor unit?
A3: The compressor includes an internal anti-reverse rotation check valve, a safety relief valve, an integrated oil filter, a discharge muffler, and NTC thermistor winding thermal sensors.
Q4: What trade terms and payment methods does Coolstart support?
A4: We accept FOB Shenzhen and EXW trade terms settled in USD, with payments supported via T/T and Western Union.
Q5: What is the sample order fee and refund policy?
A5: Sample units are charged upfront, and the sample fee is fully refunded to the client once the subsequent bulk order reaches the required quantity threshold.
