Compact diaphragm single stage supply board with cartridge - CMC280/CMC380

CMC280 - CMC380 is a compact supply board. It is ideally suited for pure and corrosive gases for high purity applications dedicated to the supply of gas to analyzers and to the creation of controlled atmosphere in laboratories, control units, and for petrochemical applications where high flows are required. The device is to be used in combination with a switchover board for the regulation of the emergency source during maintenance on the principal source. This avoids installing some extension and reduces the amount of leaking points

Key advantages

Ready to install with all components pre-mounted on a board
Best-in-class pressure stability with Cartridge Technology
Cartridge technology increases regulator life and reduces ownership costs
Can be equipped with a collection tube on the relief valve and purge outlet
Can also be equipped with an outlet shut-off valve
Can be connected to an alarm box using contact gauges
