Diaphragm single stage manual switchover board – CC283/CC383
Equipment for gas systems > Speciality gas equipment > Supply & switchover boards
The CC283 - CC383 switchover board for specialty gases is a manual switchover board. Ideally suited to insure gas supply from many high pressure sources of high purity non-corrosive gases with low flow (up to 25 Nm3/h). The device 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
  • Ultra compact switchover board
  • Ready-to-install system with all components pre-mounted on a panel
  • Can be equipped with a collection tube on the relief valve and purge outlet
  • Easy-fix system: Can be delivered on a fixation rail for easier and quicker installation
  • 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 or purging valve
  • 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
