Trail of strength.

As each country searches for renewable energy sources, andreducing their carbon dioxide emissions, wind energy pre-vails as one of the most trusted and viable solutions. Windturbines are in use today all over the world, and continue toprovide clean and reliable energy to the end user.

Renewable. Reliable. Unparalleled.

We use maintenance-free, temperature independentcapacitors, which apply the appropriate amount of powerto the pitchcontrol in the event of power failure. Withmore than 1 Mio. load cycles of the powercaps and thehigh quality standard of our industrial series components,our pitch systems are main-tenance-free for the entire lifeof the wind-power-plant.

The redundancy of our systems is guaranteed for anoptimal and safe working environment. Our productalready adheres to standards that will affect the windturbine market in the future.

Progressive Design.

The multi-redundancy of our systems is guarantor for anoptimal and safe working of your plants. Our standardtoday corresponds already to the requirements fromtomorrow. We think into the future and improve oursystems everytime anew.
