06NA2250S7NA-A00 Screw Type Refrigeration Compressor for Rack System
Product Advantages
Patented Rotor Geometry & High Displacement Output
Engineered with a high-efficiency patented profile rotor geometry, this screw type refrigeration compressor minimizes internal gas leakage gaps to deliver maximum volumetric efficiency. Integrated speed-increasing gears raise rotor velocity, producing a powerful displacement of 250 CFM tailored for commercial chillers and large-scale cooling systems.
Three-Stage Dynamic Capacity Modulation
Featuring dual solenoid valve controls, this heavy-duty screw type refrigeration compressor provides flexible three-step unloading (100%, 66%, and 33%). This variable load-matching capability enables precise cooling management under fluctuating thermal loads, significantly optimizing operational energy usage at partial loads.
Heavy-Duty Mechanical Drive & Comprehensive System Safety
Built with high-precision SKF or NSK rolling bearings and reinforced thrust bearings, the mechanical assembly easily handles continuous axial loads. An internal check valve prevents shutdown rotor reversal, while an integrated safety relief valve, oil filter, and muffler protect internal mechanisms and maintain quiet operation.
High-Efficiency Motor with Winding Thermal Safeguards
Designed for global industrial power supply standards, the 100 HP motor supports Star-Delta conversion and DOL starting modes. Direct thermal protection is continuously ensured by embedded NTC thermistors across the motor windings, supported by fine suction strainers that guard against fluid-borne contaminants.
Eco-Friendly R134a Compatibility & Proven Factory Quality
Optimized for eco-friendly R134a refrigerant, the unit performs reliably in air-cooled and water-cooled refrigeration systems. Every unit undergoes 100% factory run testing and a 33-point quality inspection to ensure mechanical integrity, low vibration, and long service life.

Frequently Asked Questions
Q1: What are the main parameters of the 06NA2250S7NA-A00 screw type refrigeration compressor?
A1: This 100 HP model delivers a high displacement of 250 CFM, operates with eco-friendly R134a refrigerant, and is engineered for air-cooled and water-cooled commercial chillers.
Q2: How does the capacity control system function on this unit?
A2: Dual solenoid valves actuate internal capacity controls to adjust output across three step positions (100%, 66%, and 33%), enabling precise thermal load matching and optimized power consumption under partial loads.
Q3: Is an economizer included on the 06NA2250S7NA-A00 model?
A3: No, this specific model is configured without an active factory economizer, though it retains standard 1-3/8 in interface dimensions and robust volumetric internal components.
Q4: What is your standard lead time for order?
A4: In-stock samples and standard single units ship within 3 business days, while complete bulk production orders are dispatched within 10 to 15 business days.
Q5: What are your primary payment terms and export shipping methods?
A5: We accept T/T and Western Union payments under FOB Shenzhen or EXW trade terms in USD. Equipment is packed securely in export-grade wooden cases (shipped with refrigerant for sea freight, without refrigerant for air freight).
