Hydrogen with purities up to 5.0 and 300 bar technology
Messer has a cryogenic hydrogen post-purification system at its filling plant in Siegen, Germany. Here, the hydrogen supplied from the production plant in Castrop-Rauxel, Germany, is freed from unwanted impurities, such as oxygen and moisture. Its quality is thus increased from 4.5 to 5.0, enabling this hydrogen to be used for highly demanding tasks, for example in laboratories. Filling in 300 bar cylinders/bundles enables significantly higher storage volumes, which are about twice as high as with 200 bar technology.
