Eberspaecher Group Supplies AC135-230 Air Conditioning Systems for Skoda Electric Trolleybuses in Esslingen

Eberspaecher Group has secured the supply of AC135-230 roof-mounted air-conditioning systems for 52 Skoda Group battery trolleybuses under Esslingen's 100% Electric Public Transportation project. The initiative is designed to eliminate local emissions across the city's public transport network by the end of 2026. The HVAC systems will be installed on both single-section and articulated trolleybuses, ensuring passenger comfort while supporting the transition toward cleaner and more sustainable urban mobility.

The new trolleybus fleet consists of 12-meter single-section vehicles and 18-meter articulated models. These buses are engineered to operate using overhead power lines as well as battery-electric propulsion, enabling them to travel up to 25 kilometers without requiring contact with overhead wires. This operational flexibility allows the vehicles to continue serving routes where catenary infrastructure is unavailable while maintaining reliable public transportation services.

The first two trolleybuses have already been delivered to Staedtischer Verkehrsbetrieb Esslingen am Neckar SVE, the municipal transit authority in Germany. The remaining vehicles will be supplied in multiple phases through the end of 2026, supporting the city's roadmap toward a fully electric public transport system with zero local emissions.
