Heller AG, located in St-Margrethen (Switzerland), has 10 employees and specialises in energy management systems for heat pumps, commercial and industrial cooling installations and refrigerated transport.
The company currently has refrigerated trucks including the Electro Truck which it hires to customers such as Frisco-Findus, Migros, Stadler Rail, and South-East railways.
Designed by Renault, the Electro Truck has an all-up weight of 13 tonnes and operates entirely by electricity.
Its large batteries are accommodated within the chassis. Given this new setup, Heller revised the design of the refrigeration system it normally uses in order to reduce its size to fit into this new truck.
