Excellence in Wind Turbines 10 - 40KW
The maximum technology and the minimum cost. The new Enair and Lancor project is to develop this new concept of wind turbine and get energy starting to run with less of 2 m/s.
Great generation capability
Mechanical and aerodynamic efficiencyCareful aerodynamic design makes it begin to generate even at very low winds. star in 2 m/s and run since 30 m/s
The pitch control system allows the generator to produce the maximum power from the start of the rotation up to its limit conditions is in a stable way.
The large optimized rotor makes it able to extract a greater amount energy obtaining the energy from lower winds than competitors.
Greater safety than ever
4 safety systems, active and passive.A safe product is one that operates predictably despite the circumstances and due to this our generator includes 4 protection systems.
- Active mechanical brake
- Aerodynamic Design of the blades to have a flag position for no capability to turn in the worst wind conditions.
- Passive spring safety that puts the blades in the previous descripted flag position when all else fails.
- Active pitch control, with electromagnetic brake.
Low noise in all conditions
low RPM and special aerodynamic profile to get no noise.Specially designed to be silent. The maximum speed of the blades is 52 m / s which makes no extra sound; the careful aerodynamic design makes the air to flow smoothly over the blade causes the noise to be half the competitors in operating conditions.
The airfoil is a combination between NACA and FX designed solely to maximize and minimize noise generation.
Electronic control and monitoring
All the parameters controlled and monitoredA great product that also says that the benefits are very good let you check the overall system performance by monitoring it.
To optimize the production and provide the system with added safety we have decided for active pitch control which has been specifically designed for this application by hand and the experience of Vacon SL
Wind turbine design and innovation
4 safety systems is a 70% more than the marketHistory
Since 1970, we've been developing the small wind turbines, our president David Bronay, started building 100W turbines with wood blades and now we are working with one of the most advanced wind technologies.
Today our human team have installed more 5000 wind turbines in all the world and now is the moment of a new evolution. The next generation of wind turbines go to use transductive technology to get a total control of each component, warranting a perfect synchronization.
In 2013, Enair started to work in a new technology of windturbines thinking that in a early future the wind technology of small turbines will be able to all the people. Then we started to develop a new technological concept to approach the big turbines systems to the small wind turbines in a way the prices would be cheap.
2014 was the year that we show the technology to Europe and explain all carefully. Our new technology will let maximize the wind energy conversion to electrical energy with high efficiency and with profitability that was one of the first’s keys to get the SME instruments to start the project.

Pitch Control
Explanation of the active pitch control
The active pitch control allows the position blade for production varies for each engine rotation speed and wind speed from the beginning up to high wing speeds.
The fact of having an active pitch control makes the blades to rotate on their axis and thus the necessary force is generated at all times to maximize energy production and protect the blade from the overspeed in moments of very strong winds.
The benefits of mechanical simplicity and advanced electronics are combined to make a perfect tandem and maximize the energy production.
For the operation uptake it is started with an optimum angle for maximum power generation and reach until the point of operation more quickly and take advantage of low winds to produce significant energy. From there the angle is increased depending on the wind speed and the rotor rotation to allow the generator to produce its maximum at all times so that production is maximized over the entire range of winds, specifically in the lowest, which are the majority.
Explanation of blade design
Highly efficient and visually esthetic design of the blades which has been the result of a combination of experience in the design of wind turbines and the most modern techniques of computational fluid dynamics. With these two elements it was obtained a design that is capable of generating a large torque in a silent mode so that it can afford to produce the same amount of energy in lower speeds. It has also been chosen a large catchment area for great powers and lower rpm for redundantly getting more power with less speed and noise.
Blade Design
Aerodynamic Designs
Explanation of the CFD and aerodynamic designs
For the full wind turbine design it has been done a complex aerodynamic study based on the most modern techniques of computational fluid dynamics. In this case the studies have required a very high computing capacity and expert knowledge because conditions are complex due to wind turbines of these powers are often placed in environments that an ideal flow is not always possible and turbulences as near to the surface produce unexpected additional loads in many cases.
The aim of this large investment of resources has not been another than optimization, finding the extra point that makes the difference with the rest.
In relation to the blades have sought the design as optimal; so that the maximum force occurs causing the least possible noise what we think are the critical points of view for the machine efficiency.
As for the nacelle and the complete design the targets have been the best way to point with the least disturbance to the flow that reaches the rotor. For the pointing after a large number of simulations has been seen that the optimum angles of inclination of the blades and the nacelle are employed; and it has been shown in the ease of orientation that it has.
Explanation of the electronic control and monitoring system
To say that a product is the best it is necessary to prove it, so we have chosen to provide a complete system of monitoring various parameters of the wind turbine for the user at all times to watch the production and the state of purchase, even from the Internet, without being required to be in the place.
The implemented monitoring system has been the result of the convergence of opinions between the group of experts who have worked on the project and the experience. The design of the generator, aerodynamics, wind dynamics and the need to optimize the production without neglecting safety have been taken into account for the full project.
Therefore the control system is based on the power obtained by the generator at all times and wind speed. This way you can apply the appropriate motion in the pitch control so that production is maximized in all cases. Also when the power exceeds 10 kW reduces the angle of the blades to produce less torque preventing the overspeed and ensuring nominal production for which it has been designed, ensuring the integrity of all elements.
The control mechanism has a very fast working time so there is no time for power losses and is very important to emphasize that always makes it under the action of passive spring so that if a fault in the control system occurs the security is not going to be compromised..
