From Local Contractor to a Leading Innovator

Founded in 1967 by Klaus Plueth in his private garage, the company quickly grew and soon started the transition from being a pure wholesaler for heating supplies to a controls contractor. In 1985, the first free-programmable DDC controller was developed, and its subsequent success led to the development of an independent business division that would become what is known today as DEOS AG.

In 2002, Klaus’s oldest son Stefan Plueth, took over the company’s management and oversaw  DEOS’ significant international growth. To this day, the Plueth family, across two generations, remains a central driver in DEOS AG’s day-to-day business and plays an active part in shaping the company’s development and culture.
