Shandong Longertek Technology Co Ltd

Langjin Technology achieved operating revenue of 321 million yuan in the first half of 2026, supported by its dual-engine strategy of rail transit and new energy. Its international footprint continued to deepen, while new growth areas such as the low-altitude economy and energy storage thermal management accelerated. In the rail transit segment, the company won new contracts for the Grenoble tram project in France and additional orders in Rome, and now has 1,100 units operating across eight overseas cities. It also secured maintenance service orders in five key Chinese cities: Fuzhou, Suzhou, Xi'an, Nanning, and Beijing. In new energy thermal management, the company passed BYD's standard configuration supplier audit for buses and expanded its standard-fit share with manufacturers including CRRC Electric Vehicle, FAW Bus, and Geely Commercial Vehicles. In the low-altitude economy sector, it partnered with leading manufacturers to complete heat pump air conditioning system development for the Volant VE25-100 and COMAC CE25A electric aircraft, and obtained AS9100D aerospace system certification. Cumulative shipments in energy storage thermal management exceeded 80 gigawatt-hours, with innovative products such as an all-in-one integrated liquid cooling unit launched. In addition, the company developed a full range of intelligent variable-frequency heat pump drying products and is advancing intelligent operation and maintenance projects across multiple metro lines.
