  • KEPCO Develops SF6 Recycling Device to Combat Greenhouse Gas

    The KEPCO Research Institute has been developing SF6 refining and decomposition technology since 2016. In June, the research center completed the development of SF6 refining equipment. SF6 becomes a solid matter at a temperature of minus 100 degrees Celsius. An SF6 refining device keeps SF6 and emits other gases at this temperature.
