For Stiebel Eltron, a company based in Unterminden, D'art staged the brand campaign "clear line" with a new stand concept at the ISH 2019 trade fair in Frankfurt.

This clear line also led in the interactive product configurators that enabled Realtime Visions to make the company's extensive product portfolio available and accessible.

After the fair, the product finders, in the form of tablet applications, continue to be used by Stiebel Eltron.
