DAFA RotaSeal for wind turbines
Durable sealing solutions for rotating parts in wind turbines.
DAFA is a trusted partner with decades of experience in solutions for the wind turbine industry – onshore and offshore.
DAFA supplies the world’s largest manufacturers of wind turbines with products for the transportation, construction and operation of wind turbines.
Our solutions absorb vibrations and noise, and protect the structure and electrical components from the ingress of water, oil, salt, sand and dust. With materials designed to meet industry requirements and needs, the customer is always guaranteed a lasting and durable solution.
Our effective solutions help reduce down-time, accident risk, wear and maintenance costs during transportation, construction and operation for more than 100,000 active wind turbines worldwide.
We offer a large variety of nacelle solutions. These solutions help structures and electronic components in the nacelle to withstand significant stress, perform better and last longer.
We supply solutions that optimize blade production, safety and operation. During production, our sealing solutions ensure that the connection between the two blade halves does not permit air ingress.
During transport, we improve blade safety and visibility using protective equipment designed to prevent shocks and wear – improving safety for the handling staff.
Our solutions also avoid the need for inconvenient repair costs, from production to operation, and delays to turbine installation due to damage to components.
Our solutions for tower structures improve safety, avoiding accidents and making maintenance easier. This reduces operating costs and increases the durability and service life of the tower. Our tower solutions also help make transportation safer, thereby reducing the number of expensive repairs.
