Segment management drives growth
Engineering
Whether it’s the energy transition or the optimization of work and production processes, engineering is the foundation of successful change. Interconnecting production with cutting-edge information and communication technology creates space for new growth models.
The megatrends of digitalization and sustainability are the driving forces behind these developments.
The companies that currently make up the INDUS Engineering segment support the manufacturing industry today with a broad range of products and services. They are established names in the specialized field of machinery and equipment construction, and niche suppliers for automation and robotics, sensor technology and measuring/ control engineering.
Axel Meyer is the Board member responsible for the Engineering segment.
Infrastructure
Growing mobility and advancing urbanization, increasing digitalization and sustainability are the megatrends providing lasting momentum to the construction industry. Public investment in infrastructure for the maintenance and expansion of traffic routes, high capacity requirements in residential construction, and energy renovations are driving demand.
Construction and building technology are gaining ideas from the social demand for sustainable building. Modern technologies enable intelligent infrastructures and supply networks for telecommunications and energy supplies.
The companies in the INDUS Infrastructure segment exploit their stable positioning to develop their ranges and focus on these needs – in the fields of construction and building technology, telecommunications infrastructure, and air-conditioning technology.
Dr. Jörn Großmann is the Board member responsible for the Infrastructure segment.
