Small Wind Turbine Enair 70PRO
The most advanced technology on the market.
The wind turbine E70 PRO , is designed to meet the energy demands of any home, gas station, farm or small business. Its high efficiency allows us to generate energy with very low wind and, in turn,it efficiently support strong wind generation. Production more than 80kWh/day , with winds average between 8 and 12m/s , thus being one of the best wind turbines on the market In its category.
The new designs have been realized strictly following the IEC 61400-2 standard, innovating in techniques such as Computational Fluid Dynamics, for aerodynamic optimization. These techniques of the Aerospace industry, increase the efficiency in energy generation and cause a total absence of noise while giving great strength to the whole, turning it into a professional machine with high performance and a lifetime warranty of more than 25 years .

Able to extract the maximum energy from the wind
The wind turbine Enair 70 PRO, has a large blade diameter of 4.3 m which in turn is optimized with Computational Fluid Dynamics obtaining a profile performance of 96%, which E70PRO is able to extract the maximum energy of the wind at low speeds and get its nominal power between 10 and 12m/s. After the tests of the certifications, the results for this model are highly satisfactory, as it gets very close to the betz limit for winds between 1 and 6m/s.
Of this model there are records of wind generation of more than 90kWh/day, in windy areas, which gives us a very high energy efficiency regime.

The most advanced technology of the wind farm
Mínimum noise
The noise is around 1% above ambient noise, being practically invaluable to our ears.
Safety-Brake
New mechanical safety system to the axle that guarantees braking under the most adverse conditions, for winds even greater then 70m/s
Anticorrosive
Treated with epoxy paint it becomes to a set of anti-corrosion and antisaline ideal for islands and coasts.
Maximum efficiency
It works with a simple breeze of 2m/s and continues to run over 40m/s without losing productivity efficiency.
Remote-Control
Combined control with the Victron Venus that allows the wind turbine to run/stop remotel.
Storm-Detection
Intelligent storm detection algorithm and safety lock of the fully automatic wind turbine combined with the Safety-Brake.
Anti-Icing and Hermetic
Structural resin acrylic urethane with an anti-ice chemical composition and maximum resistance for temperatures up to -50°C. Hermetically, perfect for coastal or desert areas.
Hardy
In order to withstand strong winds and offer a long operating life of more than 25 years, all parts of the equipment are oversized according to the IEC 61400-2 standard, this implies safety factors of 9 in many cases.
BBS (Battery Brake System)
Intelligent system that measures the level of battery charge and allows the wind turbine to stop when the battery reaches the setpoint voltage, resuming when the load level drop.
Pasive Pitch Control
Pitch control operation
The active pitch control of 2 speeds is the latest technology in small wind turbine to absorb strong winds maintaining the production of energy of constant form. This patented technology has two phases, the first one that absorbs the wind gusts and another one that in case of very strong winds maintained.
