Company Company structure

Future oriented

Company structure

DEOS AG is a manufacturer of modern building automation systems and part of the Swedish REGIN Group. Our aim is to optimise our product and solution portfolio to meet the needs of our system partners and their end customers. With our DEOS experts, personal support and active partnership, we work with commitment every day to continuously improve these values – for the success of our customers.

DEOS AG is confidently facing up to the current market conditions with a lean and agile organisation and two closely cooperating business divisions. In this way, we combine our many years of industry expertise and our competence in the fields of building services, HVAC, I&C and IoT to create a future-oriented company.

This is precisely what sets DEOS AG apart from other market players and makes us unique in the industry. DEOS AG also benefits from the advantages of the REGIN Group in the background.

Certified system partners, enthusiastic specialist planners, building operators/owners and service providers obtain the entire portfolio and services of DEOS AG and the REGIN Group within the DACH region centrally from DEOS AG.

DEOS Solutions and Products (S&P)

As a manufacturer and sales organisation for building automation, the “Solutions and Products” (S&P) division forms the core business of DEOS AG.

This is where we develop and produce our hardware and software products for the automation of buildings and for more effective energy utilisation. Thanks to our own SMD production, we can react more flexibly and independently to the requirements of our partners and the market. Our continuous delivery capability makes us a reliable partner for our customers.

The active involvement of our more than 300 system partners and their feedback plays a key role in our product development process. In addition to this close exchange, the DEOS “Projects and Services” (P&S) division regularly provides us with impetus to continuously optimise our product and solution portfolio. This enables us to guarantee practical solutions that can be integrated quickly. To make our partners even more successful – with intelligent technology for buildings that inspire.

The core target group of the S&P division is our constantly growing system partner network of system integrators around the world.

DEOS Projects and Services (P&S)

The long-standing entrepreneurial roots of DEOS AG lie in the “Projects and Services” (P&S) division. This division acts as a “system integrator under its own roof” of DEOS AG, which exclusively realises I&C projects up to 80 km around the Rheine and Oberhausen sites.

The service portfolio ranges from the realisation of building automation projects to the maintenance and support (service) of HVAC systems. System partners of the “Solutions and Products” division appreciate this very much. Not only are DEOS products tested in the field at P&S, but experts from the DEOS technical support team are also constantly undergoing further training.

In this way, we learn from the daily use of our own products and solutions and develop them further in a targeted manner. This strong project commitment opens our eyes to the requirements of our system partners. This is what makes DEOS AG so unique as a company.

In addition to building owners and investors in non-residential buildings, end customers (building owners, local authorities, etc.) from the immediate region are also part of the “Projects and Services” division’s target group.

DEOS is part of the Regin Group
