The aerodynamic noise, which was a weakness of conventional wind turbines, has been significantly reduced!
The "Lens Wind Turbine (R) 3kW model" is designed for a short diffuser, making it a compact wind turbine that is strong against strong winds and has significant advantages in manufacturing and installation. The vortex generated by the "lip" of the diffuser creates a pressure difference before and after the diffuser, causing the wind, which is accelerated by about 1.5 times at the blade tips, to turn the turbine. Unlike conventional wind turbines with sharp-tipped blades that rotate at high speeds, the soft image created by the ring of the diffuser surrounding the blades allows it to blend easily into the surrounding landscape without compromising the scenery. 【Features】 ■ High efficiency due to increased inflow wind speed ■ Reduction of noise generated by tip vortices ■ Improved aesthetics due to the round ring of the lens *For more details, please download the PDF or feel free to contact us.
