Excellence in efficiency

With the N131/3900, the Nordex Group offers an economical turbine for IEC-III locations with a maximum efficiency in the 3 mw segment. Thanks to the rotor sweep and high rated output, it obtains much higher yields. The turbine is available with hub heights of 84 to 134 meters and is thus ideal for complex locations. The maximum rated power can be adjusted (e.g. 3 MW) to also meet project-specific grid requirements. Nordex limits the sound power levels of the N131/3600 to a maximum of 106.2 decibels.
