The UE22+ is designed for use in regions with low wind speeds. It starts rotating at 1 m/s wind speed and starts producing power at a wind speed of 2  m/s. The robust construction without wearing parts makes this product low maintenance and it works reliably even under extreme weather conditions. Key features:- Six times more powerful than vertical axis models of same dimensions - Three times more efficient than horizontal axis of same dia , this model sports just 1.8M rotor- Absolutely noiseless operation- Best for extracting energy from Exhaust / waste winds from commercial roof top exhausts  / industrial exhausts. - Typically 10 to 15 hp blowers continuously  spew out winds at 8 – 15 m/s 24 /7. About 1.5 to 2.5 KW can be fed back to grid using UE22plus 3D.- Energy savings achievable to the tune of 8000 to 9000 KWH per annum under these conditions.
