    Due to the above reasons, SF 6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin SF 6. ENERVAC produces a complete line of SF 6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.
