Automotive supplier Witzenmann specialises in flexible metal elements. A furnace for brazing and solution annealing of automotive components was installed at the firm’s site in Vlkanová in 2015. Since the furnace went into operation, Messer has been supplying the company with nitrogen and hydrogen. With a second furnace the production capacity was doubled. In order to meet this increased demand for hydrogen, Messer has installed a 95-cubic-metre tank at the factory site. It replaces the eight hydrogen bundles used until now. Safety regulations and local conditions necessitated the construction of an eight-metre-high protective wall around the tank.
