In collaboration with Regionalwerke Baden \(RWB\), the devices were installed in a 5\-bar gas distribution station under real network conditions\. All three devices ran in continuous operation through to 2026\.
- [gasQS Technology in Glass Manufacturing](https://mems.ch//gasqs-technology-in-glass-manufacturing/): Among industrial gas consumers, the manufacturing processes in the glass industry are among the most sensitive thermal processes in terms of gas quality\. This is due not only to the strong focus on energy efficiency and the reduction of pollutant emissions, but also to the direct impact of gas quality on the final product\. Gas composition refers to the composition and quality of the gases used in the melting furnace as well as in various production steps\.
