The Heli Wind Turbine is a wind generator that is ideal for inland locations. Depending on the selection, it is specially designed for battery charging from 48 volts or on-grid grid feed-in.
An azimuth bearing is only additionally installed in our helicopter model, the bearing is designed as a double-bearing plain bearing and is equipped with grease nipples for relubrication.
The repeller blades and nacelle cover are manufactured and painted using the hand lamination process.
