06TTA266 Semi-Hermetic Industrial Rooftop AC Screw Compressor

The 06TTA266 ac screw compressor is designed for heavy-duty commercial HVAC systems, air-cooled chillers, and large industrial climate control units. Rated at 120 HP with R134a refrigerant compatibility and an economizer circuit, it delivers robust thermal efficiency and high volumetric output under demanding cooling loads. This compressor provides HVAC system contractors with a reliable power core that reduces system downtime and ensures consistent cooling performance.

In large-scale air conditioning applications, varying building occupancy and ambient temperatures lead to energy waste and mechanical stress during partial-load conditions. The 06TTA266 ac screw compressor addresses these efficiency challenges with continuous 25% to 100% stepless capacity modulation, balancing energy consumption directly with dynamic heat loads. Precision SKF/NSK bearings and built-in check valves prevent backspin and reduce rotor wear over extended operating cycles.

Featuring a semi-hermetic architecture optimized for air-cooled R134a systems, this ac screw compressor maximizes thermodynamic heat transfer through advanced rotor profiles. An external oil filter and standardized 4-1/8 inch suction and 3-1/8 inch discharge ports streamline routine servicing. Integrated NTC winding sensors and safety valves ensure reliable multi-voltage operation across international grid specifications.
