sf6 o2 process toshiba

Dilo was the first company ever to deal with the problem of handling sulfur hexafluoride (SF6) back in the 1960s. Sulfur hexafluoride is used as an insulating gas in electrical switchgear. Dilo has developed technical solutions that prevent this climate-damaging gas from entering the Earths atmosphere.
