oem sf6 n2 Canada

24/8/20173. Is sf 6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the sf 6 gas is always used in gas-tight compartments, greatly minimising leakage.Get price
