Massachusetts Department of Environmental Protection Reducing Sulfur Hexafluoride (SF6) Emissions from Gas-Insulated Switchgear (310 CMR 7.72) SF6 is a strong greenhouse gas (GHG), with a global warming effect nearly 24,000 times greater than carbon dioxide. SF6 also lasts in the atmosphere for more than 3,000 years after it is released.C37.122.3-2011 - IEEE Guide for Sulphur Hexafluoride (SF6 ...

Due to the above reasons, SF6 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 SF6. ENERVAC produces a complete line of SF6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.SF6 Gas hitachi and abb Reclamation factory-sell-directly
