Company Company structure

Future oriented

Company structure

As a manufacturer of modern building automation, it is essential for us to tailor our product and solution portfolio to the needs of the market, as well as to demonstrate our innovative strength with new technologies and solutions. In order to meet this environment nowadays and also in the future, DEOS AG is divided into three business segments that cooperate intensively. In this way, we combine our know-how and expertise from the fields of building services, HVAC, I&C and IT to form a future-oriented overall company. This is exactly what distinguishes DEOS AG from other market competitors and makes us so unique in the industry.

Our system partners and customers such as investors, specialist planners, integrators, FM service providers/operators and operators obtain their services centrally from DEOS AG and not from the individual business units.

DEOS Control Systems

The central unit of today’s DEOS AG is “DEOS Control Systems”, which represents the core business of DEOS AG as a manufacturer for building automation. It develops and produces innovative hardware and software products for the automation of buildings and plants in its own SMD production. The feedback from our more than 300 system partners worldwide is the foundation of our products and solutions. In addition, impulses from the business units “DEOS Building Automation” and “DEOS Building IT” shape the product and solution portfolio of “DEOS Control Systems”. In this way, we ensure and guarantee a market-oriented and practice-oriented development. For buildings that inspire.

The core target group of the CS (Control Systems) business unit is our steadily growing system partner network of system integrators as well as OEM partners around the world.

DEOS Building Automation

The entrepreneurial roots of DEOS AG lie in the business unit “DEOS Building Automation”, which operates as a system integrator and DEOS product user for the digitalization and automation of buildings and facilities regionally around our headquarters in Rheine as well as around our branch in Oberhausen. The service portfolio ranges from the implementation of BA projects to the maintenance and support of HVAC systems. In this way, we learn from the daily application of our own products and solutions and develop them further in a targeted manner. We also support our technical support for system partners with know-how from the field of building automation. This strong bond with the market is what makes DEOS so unique as an overall company.

In addition to general contractors, the target group of the “DEOS Building Automation” business unit also includes building owners as well as end customers.

DEOS Building IT

Due to the increasing fusion of the IT and TGA worlds, “DEOS Building IT” develops state-of-the-art solutions for the digitalization of buildings and facilities. BIT can thus be described as an agile think tank of DEOS AG, which links the areas of IT & BA in a new way and significantly drives the industry forward with innovations. The close cooperation with the business unit “DEOS Building Automation” repeatedly presents our innovations with practical challenges. Proven products and solutions are included in the holistic DEOS product and solution portfolio.

The target group of “DEOS Building IT” includes DEOS system partners, FM service providers/operators, builders/owners as well as end customers.
