Diaphragm single stage supply board - CM104

CM104 is a supply board to use 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. It is particularly suited for pure and corrosive gases for high purity applications.

Key advantages

Possible to connect 2 gas cylinders and a gas for purging operation
Ready to install for better productivity: all components are pre-mounted on the mounting panel
Can be equipped with a collection tube on the relief valve and purge outlet, also with an outlet shut-off valve
The CM104 can be connected to an alarm box using contact gauges
Only available in stainless steel
