  • Alternatives for SF6 | 2020 | Siemens Energy Global

    In recent years, the potential climate impact of SF 6 has led to a steady increase in demand for SF 6 alternatives. Most prominent among available options are “clean air” solutions, i.e. purified air, and gas mixtures that both have a fraction of the climate impact of SF 6.

  • SF6—The Alternative Gas - NETAWORLD JOURNAL

    An SF6 gas separator uses a cryogenic process to recondition contaminated SF6 gas to 99.99 percent purity. The reconditioning process includes increasing the storage pressure of the gas to allow the start of SF 6 gas liquefaction followed by lowering the temperature by using two to three temperature changes below -40 degrees C.
