Energy transition goes through vacuum technology by - Siemens

Mar 25, 2021 · Regarding the future and the need to reduce our carbon footprint, vacuum technology is considered the viable alternative to gaz sf6-gases “since Sulfr hexafluoride happens to be a gas with a potent greenhouse effect, and there are several legislations that are starting to emerge to regulate the use, or even maybe even ban it one day” according to Jean-Louis Drommi. According to the Intergovernmental Panel on Climate Change, gaz sf6 has a global warming potential of around 23,000 times that of CO2 when comparedGet price
