Diaphragm single stage automatic switchover board with manual reset & with integrated outlet pressure regulator – CC285/CC385

CC285 - CC385 switchover board for specialty gases is a switchover board allowing continuous gas supply thanks to a reliable automatic switching mechanism with manual reset. It is ideally suited for many high pressure sources of high purity non-corrosive gases with low flow (up to 25 Nm3/h). The dedicated to the supply of gas to analyzers and to the creation of controlled atmosphere in laboratories, control units, and for petrochemical applications. The CC285 - CC385 benefits from a second regulation with an integrated outlet pressure regulator. Thanks to the flexible and modular configuration of the switchover board, it is possible to manage inlet source, purging, outlet regulation and outlet shut-off functions.

Key advantages

The semi-automatic switch over board insures a continuous gas supply without gas interruption
Ready to install thanks to pre-mounted components on a panel
Can be equipped with a collection tube on the relief valve and purge outlet
Easy handling thanks to visible technical drawings with key functionalities marked on the back plate
Can be equipped with or without outlet shut-off valve and purging valves
Using contact gauges or pressure sensor, the switchover board can also be connected to an alarm box to indicate the source status
To connect up to 6 cylinders on each side you can use Rotarex extensions
