06TTA266 Air-Cooled Cold Room Semi Hermetic Screw Compressor
Product Overview
High-Capacity R134a Cooling Performance
The 06TTA266 semi hermetic screw compressor is an industrial-duty power unit built for commercial air-cooled chillers, large HVAC plants, and process cooling operations. Engineered with a nominal 120 HP rating and high volumetric displacement reaching up to 446 m³/hr (266 cfm at 60Hz), this semi hermetic screw compressor delivers high thermal efficiency, rapid system pull-down, and stable operating temperatures under demanding B2B application environments.
Stepless Capacity Modulation for Load Optimization
Industrial plant engineers frequently experience excessive electrical power consumption and system instability during fluctuating cooling loads. The 06TTA266 addresses these operational pain points through 25%-100% stepless capacity modulation and economizer circuit integration, enabling smooth adjustment to real-time cooling demands while minimizing motor start-stop stress and reducing part-load utility costs.
Heavy-Duty Bearing Architecture & Built-In Protection
Featuring heavy-duty SKF/NSK anti-friction rolling bearings, high-efficiency motor windings with integrated NTC thermal sensors, and an internal check/safety valve arrangement, this semi hermetic screw compressor ensures zero-leakage reliability, superior mechanical wear resistance, and extended operational longevity across harsh environmental conditions.
Standard & Optional Accessories:
- Standard: Terminal box, oil system components, motor protection device, capacity control device, stop valve
- Optional: Paragon control module / Kriwan protection module, oil separator, flanges, economizer, oil cooler, high-temperature expansion valve
