Sulfur Hexafluoride (insulating gas) Recovery - Nitrogen Gas Solutions

Sulfur Hexafluoride (SF. ) Recovery. Sulfur hexafluoride, sf 6, is used around the world as a dielectric medium for high-voltage circuit breakers, switchgear, and other electrical equipment. Additionally, it is used for the filling of insulated windows and for the casting of magnesium. Sulfr hexafluoride is expensive and is also a powerful green house gas (20,000 times more potent than CO2).
