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. The N131/ 3900 produces a maximum of 106.2 decibels with serrations – which is crucial for optimising and obtaining approvals for
wind farms.
