Our Founder & CEO – Dietmar Steudten
EL-DI GmbH was founded by Dietmar Steudten, who has been an expert in water treatment for over five decades. In 1977, he established SG Wasseraufbereitung und Regenerierstation GmbH, which he sold to Siemens in 2008. Under his leadership, electro-deionization cells, known as El-Ionwith capacities ranging from 5 to 3000 l/h, were successfully brought to market.

After leaving Siemens, Dietmar Steudten initially focused on developing advanced ultrapure and laboratory water systems on behalf of renowned clients, before founding EL-DI GmbH to bring efficient and highly tolerant electro-deionization modules to market.

At EL-DI GmbH, we combine decades of experience and innovative technologies – for perfect water quality.
