UNIPRO Semi Automatic Gas Changeover panel provides continuous gas supply without interrupting the system during cylinder changeout. Semi-automatic panels handles two cylinder banks at a time. When the pressure at one side (the primary side) reaches a pre-set value the manifold “switches” to the other side. This means that it is possible to change the gas cylinders without interrupting the gas flow. After the cylinders at the primary side are changed the handle is turned, thus changing the secondary side (delivering the gas) to the new primary side.
