  • SF6 Gas Recovery | Zero Emissions of SF6

    SF 6 is a fluorinated gas (F gas) with the highest global warming potential. It is one of the six gases subject to monitoring under the Kyoto protocol. Relating to the greenhouse effect, 1 kg SF 6 corresponds to a GWP value more than 22,800 times higher than that of CO 2. Therefore, SF 6 has to be used in closed systems in order to avoid emissions. This is exactly where our core competence - as the world wide leading manufacturer of emission-free gas handling products for medium and high
