Backup Systems

Automatically supply backup gases

High-purity backup systems from Air Liquide are designed to provide automatic backup gas supply when gas generators, cryogenic dewars, compressors or house-line specialty gases are the primary source of process gas. They allow supply systems to be turned off for service or maintenance without disturbing the gas flow to high-purity applications. Unlike changeover systems, these backup systems automatically provide backup gas as needed, buffering deficiencies in supply pressure.
