TK Launches Flagship LEGEND Trailer Refrigeration Unit with Asian-based Production
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.
