06NA2174S7EA-A00 90HP Commercial HVAC Screw Compressor for Hotel

Engineered with high-efficiency patented profile rotor geometry, this HVAC screw compressor minimizes internal gas leakage gaps to achieve high volumetric efficiency. Built-in speed-increasing gears optimize rotor velocity, delivering a robust displacement of 174 CFM for air-cooled and water-cooled chiller applications.

Equipped with a dedicated 1-3/8 in economizer port, this 90 HP HVAC screw compressor supports subcooling operation to maximize thermodynamic efficiency. Under both full and partial load conditions, economizer integration significantly boosts refrigeration capacity while maintaining optimal power consumption.

Featuring dual solenoid valve controls, the unit provides reliable three-step capacity regulation (100%, 66%, and 33%). This dynamic load-matching capability enables precise cooling management in response to fluctuating thermal loads, effectively reducing operational energy costs.

Built to withstand rigorous commercial duties, the mechanical drive incorporates high-precision SKF or NSK rolling bearings and a reinforced thrust bearing structure. The internal assembly integrates a check valve to prevent reverse rotation at shutdown, an internal safety valve, an oil filter to stop debris contamination, and a gas muffler to reduce operating noise.

Designed for 50Hz and 60Hz universal voltage standards, the 90 HP motor supports Star-Delta (Y-Δ) and Direct-On-Line (DOL) startup modes. Complete protection is ensured via built-in NTC thermistors for real-time winding thermal monitoring, suction strainers, and precision slide-fit tolerances for stable, long-term operation.

Engineered specifically for eco-friendly R134a refrigerant, the unit operates efficiently in both air-cooled and water-cooled systems. Supporting economizer integration, it maximizes cooling output across various working conditions with full factory reliability.
