Sulfur Hexafluoride (SF 6) 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.People also askWhat is SF6 recovery?What is SF6 recovery?SF6 (Sulfur Hexafluoride) Recovery. SF6 is widely used as an insulating and arc quenching gas in medium and high voltage transformers. As equipment ages, it is being repaired or replaced with more efficient equipment which typically uses 1/3 the quantity of SF6. This creates a need to recover the SF6 for recycling or disposal.SF6 (Sulfur Hexafluoride) Recovery | Hudson Technologies
