Eco & Renewable Energy

Wind Turbine Generation System, enecomTM

enecomTM is an innovative wind turbine technology developed in Japan which represents the top class of patented technology in the world. It offers environmentally friendly renewable energy.

The technologies of enecomTM have been developed by Dr. Prof. K. Seki, Tokai University, in Japan over a period of nearly 15 years as a Japanese government project.

The design of the blades is based on Professor Seki's innovative aerodynamics theory. It utilizes less, slower and variable directional wind. As a result, it enables the production of more energy and more stable production. enecomTM offers many advantages over conventional wind turbine systems.

  • Omni-Directional

All blades produce rotating force regardless of wind direction.


  • Wind Receiving Area is larger

Similar Diameter as Propeller type → Receiving area is 27% larger
Utilizes less, slower, and variable directional wind

  • Low Noise

Very quiet. Unlike conventional propeller type
Suitable for residential areas


  • Mountable to Rooftops

The system can be installed horizontally as well as vertically
Height is adjustable
Suitable for office buildings, factories, and grid towers


  • Higher Productivity

The blades are straight and its cross section is identical along blade line, which is suitable for mass production.
Low Maintenance Cost
Main body is made of steel and the blade is of Fiber Reinforced Plastic, which is very strong and promises low maintenance cost
