HEXIS fuel cell systems combine cutting edge technology
with environmentally-friendly efficiency (A++). 

Viessmann Group


HEXIS has, since July of 2015, belonged completely to the Viessmann Group. It is one of 22 production companies in this Group. Continual joint development of a Viessmann fuel cell system based on HEXIS technology is currently taking place. This successor will be brought to the market by the Viessmann Group. The production facility in Winterthur is currently being adapted for this new generation of devices.


The production of the Galileo 1000 N has been discontinued. There are no more devices available. It goes without saying that our customers are assured of sufficient spare part stocks for the devices they have already installed.



Research & Development Partner


Cooperating on a national and international level


HEXIS cooperates with numerous R&D institutions in Switzerland and the EU. These include the ZHAW in Winterthur, the University of St. Andrews in Scotland, the Jülich Research Centre, the IKTS Fraunhofer Institute for Ceramic Technologies and Systems in Dresden, and the KIT Karlsruhe Institute of Technology. Renowned suppliers are also contributing their expertise and components towards the development and manufacture of these fuel cell modules.



Market partner


Well-known partners – First-class references


HEXIS cooperates with selected partners who enable us to operate the fuel cell modules with optimized real-world practicality. These partners already meet the high requirements regarding quality and reliability of their products. Our customers gain experience with this relatively new technology – using it to test and prepare new business sectors. Our successful, stable and long-term cooperation with renowned European industry and trade partners has been continually strengthened over the past few years. 

The marketing phase for HEXIS has been completed.


Numerous fuel cell heaters are currently being operated by HEXIS partners and customers. Over 100 specialists in the sanitary, heating and air conditioning sectors, as well as from the electrical trades, have been trained to date.
