Maintenance and repair is and remains a dynamic subject. This can be clearly seen by the number of upgrades that we have developed to optimise the operation of wind turbines. Whether complex or surprisingly simple solutions – every upgrade is the result of our education, research and development processes driven by our passion for servicing and the agility of our company processes.

The exchanges between the specialist areas of the Deutsche Windtechnik and our subsidiary network ensures that the improvements are developed and applied to the right extent. In order to always maintain an overview of the desired economic effects, the technicians work closely together with the sales department and management.
