Improving wind turbine efficiency – with retrofit

Experienced and reliable partners are crucial for the modernisation of existing wind turbines, so-called retrofit or repowering, because tailor-made planning and implementation processes ensure the true success of retrofit projects. We offer you a comprehensive range of retrofit services such as the installation of service lifts, vertical ladders, or fall arrest systems. This way, we contribute to increased turbine profitability and safety. Of course, across the globe with manufacturing expertise.


We have earned our spot among the global retrofit specialists for climbing technology, with over 400 completed retrofit projects in Europe and the US over the last few years. Comprehensive consulting services, as well as first-class customer support and quick project realisation, are a matter of course for us during repowering projects.
