Diaphragm single stage automatic switchover board with manual reset – CC284/CC384
CC284 - CC384 switchover board for specialty gases is a compact gas equipment 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). It is dedicated to the supply of gas to analyzers and to the creation of controlled atmosphere in laboratories, control units, and for petrochemical applications. Thanks to the flexible and modular configuration of the switchover board, it is possible to manage inlet source, purging and outlet shut-off functions.
Key advantages
  • The semi-automatic switchover board insures a continuous gas supply
  • 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
  • Can be equipped with or without outlet shut-off valve and purging valve
  • Easy handling thanks to visible technical drawings with key functionalities marked on the back plate
  • Using contact gauges or pressure sensor, the switchover board can also be connected to an alarm box to indicate the source status
  • In order to connect 6 cylinders on each side you can use Rotarex extensions
