• Customised thermal management focused on operational reliability and energy efficiency even under extreme climatic conditions

• Compact combination units for cooling batteries and power electronics

• Future-proof: systems are Cybersecurity-ready and designed for natural refrigerants

Desert heat, sandstorms, Arctic cold or extreme snowfall: at this year's InnoTrans, technotrans is focusing on customised thermal management solutions for extreme climatic environments. The systems are designed for use in extreme climatic conditions ranging from -45 to +70 degrees Celsius and enable reliable operation of rail vehicles with high availability. Future-proofing is also a key priority: by using natural refrigerants and Cybersecurity-ready systems, the company is providing technological responses to current market requirements.

"The increasing electrification of rail transport is driving growing global demand for high-performance thermal management solutions that ensure high system availability even under extreme climatic conditions," says Bastian Thiel, Business Development Manager at technotrans. "With application-specific solutions, we help our customers to control the temperature of batteries and power electronics efficiently and ensure the reliable operation of rail vehicles in these demanding environments. At the same time, we respond to new regulatory requirements at an early stage and provide sustainable, future-proof system solutions."

Operational reliability in extreme climate zones - in heat, cold, sand and snow

Growing demand is coming, on the one hand, from desert regions, where trains and trams are exposed to ambient temperatures of up to +70 degrees Celsius and high levels of sand. On the other hand, technotrans also designs solutions for use in extremely cold environments with snow loads, icing and temperatures down to -45 degrees Celsius. Under these conditions, the thermal management system maintains a constant temperature for batteries and power electronics, thereby increasing fleet availability.

Alongside a customer-specific system, technotrans is showcasing its established, standardised BTMS technologies at the trade fair. The focus is on a unit from the zeta.rail series, which offers a high degree of configuration flexibility. Thanks to its modular system architecture, the unit can be configured with different components and equipment options to meet a wide range of rail transport requirements without extensive development work. This allows the solution to be adapted efficiently to different vehicle concepts and supports manufacturers in implementing individual requirements quickly.

Focus on cybersecurity and decarbonisation

Another key theme of the trade fair presentation is future-proof battery thermal management systems (BTMS) for the next generation of battery-electric rail vehicles. These meet the requirements of the Cyber Resilience Act (CRA) for the type approval of new vehicle models. For projects starting from 2027, technotrans will consistently supply a CRA-compliant Cybersecurity-ready version. At the same time, the company is stepping up the use of the natural refrigerant R290 (propane). It has minimal global warming potential (Low GWP) and supports operators in making their fleets more environmentally sustainable over the long term.
