In 1922, Wilhelm Siegle and Friedrich Epple founded the company SIEGLE+EPPLE in Stuttgart, Germany. With just 5 employees, they specialized in the production of fans and air heaters for the ventilation of rooms. In 1930, they built a larger factory with its own hot-dip galvanizing shop in Stuttgart-Weilimdorf and expanded production to include drying and air extraction systems. When Wilhelm Siegle left in 1937, Friedrich Epple became sole owner.

By 1950, the company already employed 60 people. Between 1953 and 1960, further production shops were constructed and in 1957 the administration building was added.

Today, S+E produces high-quality components for ventilation widely used in Germany and abroad. In the field of system construction, S+E offers a huge range of services, from individually designed one-off solutions right through to a complete take-over of entire buildings and systems. And all these services are flexibly adaptable to meet the requirements of each customer.
