Liebherr supplies R290 HVAC systems for Swiss trains
27th August 2025
SWITZERLAND: Liebherr-Transportation Systems is to supply propane-based HVAC systems to Swiss train manufacturer Stadler Bussnang for integration in 16 battery electric multiple unit FLIRT trains.
The accumulator railcars are planned to enter into operational service at Austrian Federal Railways ÖBB in 2028.
The trains in three car-configuration are manufactured by Stadler Bussnang AG and the initial delivery of Liebherr’s three saloon and two driver’s cab HVAC units will take place during this summer.
The battery trains will be operated by the ÖBB and will replace parts of the Austrian Federal Railway’s existing diesel train fleet. The FLIRT Akku trains with a seating capacity of 160 passengers each are intended foremost for use on non-electrified or only partially electrified lines along the Kamptalbahn in Lower Austria.
The propane HVAC technology developed by Liebherr is said to be easy to service and takes all relevant safety requirements, such as the flammability for the refrigerant, into account.
