The nacelle of windmill houses  

These days the average nacelle cover contains many different components and systems. Adding up every part, system, and component results in a lot of weight. We know from our experience that the typical solutions are stainless-steel products inside the nacelle covers. One of the main benefits of switching to HDPE plastic is the light weight of the material. By switching those stainless-steel products to high-quality plastic products in the nacelle covers, you can save a lot of weight.

Extremely durable windmill parts

The premium products for the wind industry are by made by our rotomoulding process. The unique aspects of our process will make sure that the plastic is evenly spread in the mold. This creates unique one-piece products which are extremely durable under pressure and heat. This is important for manufacturers of modern nacelle covers because this makes sure that during the lifetime of the windmills the premium products produced by Rotovia are durable enough to keep going for years and years.
