They are highly sensitive systems that can knock entire companies or even industries off track if they are defective: data centers, switchgear or engine control units are exposed to harmful gases or moisture around the clock. If they are not filtered out of the air, corrosion can occur and, in the worst cases, the entire system can fail. Together with her colleagues, Dr. Edith Kühl is researching the optimal solution to this problem. The idea is to use small, porous beads or pellets to absorb harmful gases, bind them or transform them into harmless salts. This process is called gas phase filtration and is far more than a product for its users. It is an insurance policy against an incalculably high risk.
