The small wind turbine is regulated by the manufacturing standards of IEC-61400. Within
these standards are subcategories of the standard such as IEC-61400-2, -12, -11, etc.
each feature sets that small wind turbines must comply with robustness, power curve,
noise, etc. requirements. Compliance with these rules is essential to ensure that a "small
wind" has the quality required therein. At present there are very few countries which
require manufacturing standards for wind turbine installations. Countries that do not
require these fulfilments, are exposed to the option that any type of home wind turbine
without safety and warranty standards can be installed. This should be avoided as it
should be ensured that only product installations with high performance and reliability are
installed.
Beaufort scale is a scale used globally to establish measures commonly used as a reference
for assigning names to certain currents of wind. This scale is important to keep in mind,
especially from grade 8 upwards, at which the wind can cause damage to the wind turbine
by swirling object.

The applications for our wind turbines are multiple and include different types of
installations, for isolated power grid installations as well as for installations connected to
the network and through energy-producing facilities.
Here are some typical installations for different uses:
2.2 Applications
For wireless telecommunications should be placed
transmission antennas in remote locations that are
capable of transmitting the signals over long
distances, on these occasions rarely electricity
reaches these places, isolated energy systems are
the guarantee for optimal operation of the station.
For facilities of farms and greenhouses, the best
solutions are Smart Grid networks that combine
renewable energy, accumulation support network
and generators. Another solution is Self-
Consumption
There are many houses and rural hotels where
access to conventional electricity grid is impossible
or economically unviable. In these cases, isolated
systems are the solution to cover the own needs.
When there is access to the electricity grid the
solution is the installation of self-consumption.
Telecommunications
Farms, small industries, greenhouses, etc.
Houses, Country Hotels,

ENAIR is a wind turbine which belongs to the field of small wind, simple operation and
easy assembly.
Targeting is done passively by a rudder that works as a weathervane, he always keeps the
aero generator downwind. Once the wind impinges on the blades, the kinetic energy of
wind is transformed into rotational kinetic energy. The variable pitch system regulates the
rotational speed for high wind speeds. The generator converts this rotational kinetic energy
into electrical energy.
Structurally the wind turbine has: a main body, which provides the connection betw een the
coupling of the tower, the helm orientation, generator and the variable pitch system, is
isolated from the outside by the cone piece, a housing protects the internal mechanism.

ENAIR has been designed for a service life of over 25 years, even in the most adverse
conditions, such as extremely salty environments or locations with high average wind
speeds.
UV resistance:
All paints used have high resistance to light and UV radiation to protect aging and fading
caused by the sun.
Resistance to high wind speeds:
The wind turbine is designed to fully maintain its structural integrity for specific wind
speeds of 60 m / s (216 km / h or 135 mph) (Class I according to IEC 614000-2 standard).
Is important to follow the safety recommendations shown in 4th point and the
maintenance planning shown in the 6th point.
Corrosion resistance:
Structural design with fiberglass and aluminium, as well as the application of surface
treatments allow the wind turbine to be installed place with extreme conditions: desert,
marine environments, etc.
To prevent corrosion of metal parts, specific nautical paintings are applied, based on
protective rubber.
Water-tightness:
The interior spaces are completely sealed to prevent moisture penetration that may
deteriorate internal components by placing a series of gaskets complete sealings.

The ENAIR wind turbine placement is as important as the available wind.
The following considerations should be taken into account:
Tower height:
In general, the produced power will be greater, as higher the tower is because the wind
speed increases with height. You must consider that a taller tower is a major economic
investment which on the other hand is most often easily amortizable.
Land shape
Normally the highest point has the best winds, although areas around river valleys, large
hills or mountains and large forests can affect the wind resource.

3.6 Where your wind turbine should be located
ATTENTION: Your dealer can provide technical assistance in locating
the best emplacement for your ENAIR.

Obstructions:
Every obstacle that interferes the movement of the wind is affecting both its direction and
speed. The most common obstructions are houses and trees. It is generally recommended
to install the tower 10 meters above any obstruction and with a distance twice the height
of the obstruction.
For example, if you have a house 5 meters tall and a tree 7 meters near where you want to
install your ENAIR 30, it should be allocated to 17 meters above ground (7 m the highest
obstacle + 10 m) 10 meters from the house (5 x 2) and 14 meters from the tree (7 x 2).
Buildings:
On buildings, before placing a wind turbine, ensure that the structure of the building can
withstand the wind turbines weight and stresses during its operation.
The wind turbine should be placed about 3 meters back from the facade of the building,
and about 2-3 meters above the highest point. Consider also the surrounding buildings and
the “ w ind rose” .

Areas where there is a clear direction of the prevailing wind:
In the environment of an obstacle an area of turbulence is produced.
Dimensions of turbulence area are defined by the height of the object.
The Location is defined by the direction of the prevailing wind
The dimensions of the area of turbulence in the downwind area (over 10H), are
conditioned by the width of the object (A):
• If A <3H → Size of area downwind 20H
• If A≤3H → Size of area downwind 10H (most common situation)
Prevailing winds:
It is important to know from where the most frequent and strongest winds come from, in
regarding of the area where you want to install ENAIR 30. To the extent possible, this
direction must be free of obstructions. In order to know this, data is gathered with an
anemometer and a wind vane to measure the direction and wind speed over a period of
time. The outcome of the measurements is called "wind rose". An example of the
aforementioned wind rose is shown below, the right shows the wind situation in summer
and the left in winter. As can be seen, they are completely different, so a detailed study of
the demand for electricity in both seasons will be very useful.
