sf 6 gas - WIKA South Africa

The plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas detectors and emission monitors.Get price

Sulfr hexafluoride 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.Get price
