PASSIVE VARIABLE
PITCH
Patented technology to maximize energy production
It is a mechanical system due to what the aerodynamic vector
of the blades is modified to obtain the maximum energy in each
case and never exceeds its rotor rpms.
E70PRO Wind Turbine
TECHNICAL PROFILE
It achieves:
Less noise
More ability to absorb high winds
More consistency in the generation
More energy with less wind
ELECTRONIC
CONTROL
System of intelligent energy management
Batteries connection:
7 types of programmable batteries (lithium, lead, gel, etc.)
Charging shunt resistor pulses if overload. The excess which
can’t be charged is derived to protect the batteries.
Grid connection:
Through the MPPT inverters, which are programmed by the
wind power curve which maximises energy times.
Compatible with triphasic grids, monophasic and European
and American systems.

A NEW DESIGN, A NEW ENERGY
When you apply the latest technology in design,
the latest simulation technology, the best materials
on the market and combine everything with more
than 40 years of experience the result is:
the best wind turbine on the market
3,4 m
Minimum noise
The noise is around 1% above ambient
noise, being invaluable to
our ears.
Maximum efficiency
MORE EFFICIENCY
A PMG with more powerful magnets and a
rotor fully integrated in the magnetic sheet,
with improved profiles of the blades makes
us with less wind to be more efficient.
MORE STURDINESS
The whole design has been developed
based on a centre of gravity positioned for
balance tension and improve the loads.
It works with a simple breeze of 2m/s and
continues running at more than 40m/s
without losing efficiency in energy production.
Anticorrosive
It is trated with cataphoresis, which
becomes a covering anticorrosive and
perfect for salt on islands and coasts.
Hermetic
Hermetically sealed alltogether, to
avoid microparticles, humidity air entering
and prevents damage to coastal or
desert areas which have a lot of sand.
MORE SECURITY
MORE ENERGY
By incorporating new materials like carbon
and the integration of the epoxy resins
with steel, the safety factors increase
reaching Fs=9.
Making all these improvements and
applying the computational fluid dynamics
we improve up to 15% at the energy
production.
Sturdiness
To withstand strong winds and offer a
long operating life all equipment parts
are oversized.
