Equipment for stable generation and supply of various gases required in manufacturing sites. Includes on-site gas generators such as nitrogen gas generators, oxygen gas generators, hydrogen gas generators, and argon gas generators, as well as gas supply piping systems, flow control devices, and purity management equipment. Used for welding and cutting operations, heat treatment processes, manufacturing processes in inert gas atmospheres, and analytical/inspection applications. Unlike cylinder supply, enables continuous and stable gas supply, contributing to manufacturing process efficiency and cost reduction.
