  • SF6 gas handling - DILO

    A service cart enables the recovery of the SF 6 gas from a gas compartment to a final vacuum of < 1 mbar. Thereby the gas flows automatically via dry and particle filters which effectively adsorb decomposition products and moisture from the gas. During the gas recovery process the SF 6 is stored either in gaseous or in liquid form. Furthermore, the air is evacuated from gas compartments after maintenance works.
