R & D and Production Site at Winterthur, Switzerland

Not only the engineering and the development of our exhaust gas purification systems but also the production of the components needed for the exhaust gas purification systems are manufactured at our production site at Elsau, Switzerland.
For instance, all filter and catalyst honeycombs, the housings for the filter and catalysts as well as the technical control systems are all produced in-house.
