06NA2250S7EA-A00 High Capacity Screw AC Compressor With Economizer
Product Advantages
Patented Rotor Geometry & High Displacement Output
Designed with a high-efficiency patented rotor profile, this screw AC compressor minimizes internal gas leakage gaps to achieve superior volumetric performance. Equipped with an internal speed-increasing gear, it delivers an impressive displacement of 250 CFM tailored for large-scale commercial HVAC and industrial chiller applications.
Integrated Factory Economizer for Enhanced COP
Featuring a dedicated 1-3/8 in economizer interface, this 120 HP screw AC compressor supports liquid subcooling operation. The economizer capability significantly boosts system refrigeration capacity and thermodynamic efficiency during peak load conditions without proportional power increases.
Three-Stage Load Regulation
Utilizing dual solenoid valve controls, the unit features three-step capacity modulation (100%, 66%, and 33%). This dynamic load-matching capability optimizes power consumption during partial-load demand and stabilizes temperature control in fluctuating operating environments.
Heavy-Duty Mechanical Drive & Built-In Safety Controls
Built with high-precision SKF or NSK rolling bearings and reinforced thrust bearings, this heavy-duty screw AC compressor easily withstands continuous axial loads. An internal check valve prevents shutdown back-spin, while an integrated safety valve, internal oil filter, and muffler protect internal assemblies and dampen acoustic levels.
120 HP High-Output Motor with Advanced Thermal Monitoring
Engineered for industrial electrical systems worldwide, the 120 HP motor supports Star-Delta conversion and Direct-On-Line (DOL) starting modes. Direct winding protection is ensured by embedded NTC thermistors, while fine suction strainers safeguard the system against fluid-borne debris.

Frequently Asked Questions
Q1: How does the integrated economizer boost performance on this 120 HP screw AC compressor?
A1: The factory 1-3/8 in economizer port connects to a subcooling loop, increasing overall cooling capacity with minimal additional power draw, directly improving overall system COP.
Q2: What startup methods and voltage standards are supported by the 06NA2250S7EA-A00?
A2: The unit supports standard global industrial voltages and allows both Star-Delta and Direct-On-Line (DOL) starting configurations.
Q3: How does the dynamic capacity control system work?
A3: Dual solenoid valves actuate internal capacity controls to regulate compressor output in three steps (100%, 66%, and 33%), enabling exact thermal load matching and lowering partial-load operational costs.
Q4: What is the typical lead time for sample and bulk orders?
A4: In-stock sample units dispatch within 3 business days, while standard commercial bulk production orders are completed and dispatched within 10 to 15 business days.
Q5: What are your trade terms and export packaging standards?
A5: We accept T/T and Western Union payments under FOB Shenzhen or EXW terms in USD. Equipment is packed in reinforced export wooden crates (shipped with refrigerant for sea freight, without refrigerant for air freight).
