CONCOA 523 Series AutoSwitch | Automatic Gas Switchover | 3000 PSIG Inlet, 316L Stainless Steel
Built in stainless steel, the CONCOA 523 Series AutoSwitch provides continuous delivery of ultra-high purity or corrosive gas in laboratories and process plants. It moves cylinder or bank priority from primary to reserve automatically without sending pressure fluctuations down the use line, and works with one cylinder per side or with a manifold such as the CONCOA 52 Series Maniflex.
Configured to order, the 523 can include internal pressure switches with warning lights or internal transducers without lights, both compatible with the Altos 2 alarm, plus intrinsic safety barriers, captured venting with pipe-away relief and a manifold extension system.
