Eocycle 25kW Direct Drive

Eocycle 25kw

Eocycle’s 25kW wind turbine represents the next generation of wind turbines. The innovative design makes the turbine safe and durable while maximizing energy production and minimizing noise. Making it ideal for use in:

  • Farms, ranches, and vineyards
  • Retail businesses and small to medium enterprises (SMEs)
  • Schools, colleges and universities
  • Government offices, pumping stations, water treatment facilities, parks, arenas, stadiums, museums, rest areas
  • Golf courses, training centers, hotels, recreational parks
  • Rural electrification for developing countries
  • Isolated sites and remote areas where diesel-powered generators are used for producing electricity (“wind-diesel”)
