Diaphragm single stage supply board with cartridge - CM280/CM380
Equipment for gas systems > Speciality gas equipment > Supply & switchover boards
CM280 - CM380 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. It benefits from duo-bloc technology.
Key advantages
