When striving to make fundamental changes to a working system, challenges are inevitable. This article examines how Siemens Energy has made a truly major step towards sustainability in the energy sector, by phasing out SF6 gas and introducing zero-emission clean air insulation gas technology for switchgear. With the vision of creating a sustainable energy supply for the future, the company has had to overcome many challenges along the way, including tightness verification in clean air switchgear. To solve this, Siemens Energy collaborated with Pfeiffer Vacuum+Fab Solutions to develop an innovative vacuum-based leak detection method.

Pfeiffer Vacuum+Fab Solutions – a member of the global Busch Group – presents the CenterLine CNR series, an expansion to the existing CenterLine family of vacuum gauges, particularly suited for the harsh operating conditions in the semiconductor industry
