Our rotary union and slip ring combinations offer multiple signals, electric and hydraulic power transmission for the hydraulic blade pitch actuation for onshore and offshore applications. These high-performance units must operate continuously in harsh environments, where regular maintenance and monitoring are difficult and expensive.Ìý

Our wind rotary unions can also be integrated with slip rings for blade heating – with both anti-icing and de-icing capabilities – to provide hydraulic and electric blade pitch control.
