CONCOA 526 Series | Pressure Differential Switchover | 3000 PSIG Inlet, Brass Regulators
The CONCOA 526 Series switchover works on opposing pressure differential: when the primary cylinder runs down it switches automatically to the reserve side, keeping high purity, non-corrosive gas flowing. It is supplied either with flexible hoses for two cylinders or with manifold connectors for the CONCOA 52L Series MicroManifold.
The series is configured to order. Named choices are a 3000 PSIG (210 BAR) or optional 4500 PSIG (310 BAR) inlet, an integral line regulator for constant downstream pressure, purge valves, outlet isolation valves, the Altos 2 remote alarm and intrinsic safety barriers.
