4.2M140 EBC

Efficient energy production in low and medium wind conditions

The 4.2M140 is a powerful turbine in our four megawatt platform for low and medium wind-speed sites. With its bigger rotor, a rated power of 4,200 kW and highly efficient rotor blades it can achieve a high annual energy production. The rotor blades are based on our Rodpack technology which is already used in the 3.XM series. With an updated gearbox design, significantly longer blades and an advanced pitch bearing, as well as a generator and full converter system, the 4.2M140 stands for more efficiency, higher availability and lower service costs.
