With our passion for innovation and dedication to quality we deliver sustainable products and solutions that can be used to combine heating, ventilation, air-conditioning and lighting systems to form an efficient overall system. This markedly helps reduce the costs for energy, commissioning and maintenance while offering greater convenience for the people who live in the building. Through integration of external systems we create synergies, so that we can provide our system partners and customers with holistic and individual solutions. You can bank on us for tomorrow’s building automation.

Where do we come from

50 years of innovation – a history with future. Continuous growth as a global player combined with the flexibility of a mid-sized family business works to benefit DEOS AG. Originally started in 1967 as “Plueth Energietechnik” Stefan Plueth expanded the business in 2002 with the foundation of “Plueth Regelsysteme”, which became DEOS control systems due to the growing internationalisation. In 2008, DEOS AG started as a holding company, in which the subsidiaries were grouped together and from 2016 on, DEOS AG is the unified DEOS company. Today DEOS AG is active for our customers at over 12 locations worldwide with more than 200 employees. It is our employees as well as system partners, building operators and FM service providers who have been passionate about ensuring high end customer satisfaction and the success of the company – for more than 50 years.

100% Made in Germany

One of the most modern production lines for surface-mounted devices (SMDs) in Europe is located at DEOS’ headquarters in Rheine, Germany. Featuring a fully automated production process for surface-mounting electronic components, up to 10,000 printed circuit boards (PCBs) are fitted here. Each single PCB is subject to stringent inspections, followed by a quality inspection, before it exits the production process. This ensures that the highest level of quality is achieved – 100% Made in Germany.

A state-of-the-art, computer-controlled production planning program is used to optimise the output rate for the SMD production line, so that it is possible to process up to 36,000 components per hour with a positioning accuracy of 3/100 mm.
Lasers will adjust the tiny electronic components that are as small as 0.5 x 0.2 mm. They are then placed on soldering paste that was applied on the PCBs beforehand, followed by being soldered in the furnace. Later on they will form the central intelligence used to control entire energy supply systems for buildings.
