The latest technology for the greatest added value

The optimised rotor aerodynamics and the advanced carbon fibre technology of the eno 126 ensure new benchmarks when it comes to economy and weight reduction. Highly innovative design solutions, paired with the robust machine design, make the eno 126 a safe long-term investment in a new generation of wind power stations.  12,500 m² of painted rotor surface make them ideal for inland sites. 3,500 kilowatt nominal power, paired with an increased turbine classification, make the eno 126 one of the most economic solutions in the wind farm.
