AERODYNAMICS
A smart blade system designed to use lift & drag forces, and to operate at low rotational speed & high torque.
High energy conversion at any wind speed
The 3-blade nautilus design system made out of carbon fibre has one of the highest efficiencies to convert wind into electrical power
Turbulence handling
The wind turbine has a higher wind turbulence tolerance compared to other conventional airfoil bladed models, making it an ideal urban wind turbine for rooftop operations
Silent
The smart system is set to operate at low rotational speed and high torque to ensure a very low noise level even with with high wind speeds
Maintenance friendly
The wind turbine is composed of parts meeting the highest industry standards to ensure hassle free operation
