MM82

The classic turbine for high wind speeds

With a rotor surface of 5,281 m2, this 2.05 megawatt wind turbine generates consistently good energy yields in high wind locations. It is based on the technology of the MM70, which was launched in 2002 and is meanwhile one of the most frequently produced types of wind turbine in the world. Hub heights ranging from 59 to 80 meters make the MM82 the ideal choice for sites with height restrictions.
