FW 2000

The 2.0 megawatt wind turbine is designed for high yields, but can also be adapted to low-wind sites (IEC 3). Large rotors with a diameter of 93 and 100 m ensure high yields. As a cold-climate version (CCV) and hot-climate version (HCV), the FW 2000 is also suitable for sites with extreme climatic conditions.
