Switchover system for high purity gases

Switchover system for high purity gases

CONCOA has designed a semi-automatic switchover system to provide a continuous supply of high purity gases for use in process plant, laboratory, university, and R&D environments. When the primary cylinder is depleted, the reserve cylinder is activated to supply gas automatically. An arrow on the adjusting knob indicates cylinder priority, and a 180o turn changes priority when the primary cylinder is depleted. The Model 520-9000 can be used with non-corrosive high purity gases, while the 521-9000, together with the 422 Series of 316L stainless steel regulators, is used with corrosive and ultra high purity gases. Both models incorporate CONCOA`s capsule seat assembly, featuring PTFE Teflon seats and 10 mm inlet filtration. The system comes complete with either flexible, all-stainless steel pigtails for two-cylinder use, or with manifold connectors for maniflex modular manifold use.
