Gases are everywhere. They are used in modern production and process engineering, in medicine and in the laboratory. Depending on the area of application, they can be used to increase product qualities, open up new fields of application, optimise manufacturing processes and make them more efficient, economical and environmentally friendly. They take on control, protective and carrier functions, supply energy, have a reactive, reductive, oxidising or inerting, cryogenic or thermal effect. The requirements and challenges are correspondingly diverse.
