3.2M114 NES – one of the quietest wind turbines in its class

With the hub height of 100 meters, the Senvion 3.2M114 was designed for medium wind speeds. Thanks to the larger rotor surface and the optimised aerodynamics of the rotor blades, these turbines can deliver up to ten per cent higher yield than the 3.4M104. Because the hub height of 100  meters rise above natural obstacles, this turbine generates high yields even in difficult terrain.
