Thermo King Launches Flagship LEGEND Trailer Refrigeration Unit with Asian-based Production

SHANGHAI, April 18, 2025 /PRNewswire/ -- Thermo King, a strategic brand of Trane Technologies (NYSE: TT), a global climate innovator, has launched flagship LEGEND series with the first Asian-made trailer refrigeration unit production line at its plant in Wujiang, China, set to serve the entire Asia Pacific market.

In line with the company's Future Factory Initiative, new production line boosts LEGEND's supply chain localization by 60%, enhancing delivery speed, stability, and flexibility to drive the cold chain logistics towards a more efficient, intelligent and sustainable future.

"Through technical advancements and collaboration with local suppliers, we've developed the industry-leading '3-in-1' motor technology.", said Helen Ling, vice president of Trane Technologies Asia Pacific, "LEGEND's localized production demonstrates Thermo King's complete capability from independent R&D to mass production."                                                                 

Building on TK's world-leading trailer platform, LEGEND series combines three core strengths: precise temperature control, intelligent operation, and energy efficiency. Its advanced electrical architecture and independent airflow control technology tailors cooling to cargo types and transit conditions. A specially designed local standby option for Asia Pacific customers can further reduce operational costs and carbon emissions.

Introducing the pioneering electrified integration solution, which combines a motor, permanent magnet generator and active rectifier, it reduces components by 27% compared with the traditional mechanical drive solution, improving the fuel efficiency by 15% with 30% lower maintenance costs and 52% reduced downtime.

The LEGEND series also features an intelligent control system. The standard Tbox telematics system uses smart algorithms to monitor unit performance in real-time, while the IP67-protected multi-language control panel offers real-time fuel consumption data and automated Pretrip check function. This integration of smart algorithms and key components delivers up to 20% fuel efficiency in actual scenario.

Certified for China GB IV emission regulation, the units are currently deployed in long haul refrigerated transport, with accelerated plans to achieve EU Stage V compliance and expand into railway applications.
