DALIPERFORMANCE

Highlights

The Dali Performance is a fully integrated, utility-connected wind

businesses. It is installed on a design- and patent-protected 12 metre wooden tower.

− −  Patented variable pitch system, which can limit rotor speed in a

smooth, proportional way to ensure constant rotation speed in high winds allowing for high energy yield

−  Advanced design of blades that ensures silent operation−  Low rotation speed that contributes to the silent operation of the

turbine

Development of Our Wooden Towers

More than 6000 engineering hours were put in the development of InnoVentum wooden towers.

design validation

The Dali XII tower was tested full scale in-house for the measurement of all critical parameters and the initial patent application was submitted early 2012.

The Dali XII tower was further tested on site.

After 12 months of testing, a second generation of the Dali XII was developed resulting in an international patent application early 2012. Since then there were multiple installations performed across several countries with excellent results.

Wooden vs. Steel Towers

2. For example, the production of steel for one 12 meter tower causes the emission of 4 tons of CO2oil. By contrast, wood material for such a tower is provided by 2 trees that have absorbed at least 1 ton of CO2 during their 45 years of growth – based on energy from the sun.

Steel towers, especially hollow tubular designs, are known for amplifying the noise and vibration coming from the generator while wooden towers absorb them.

Steel towers are known for corrosion problems, especially in humid climates and in installations with close proximity to the sea.

Steel prices in the world market are increasing at a record pace, which makes the production of steel towers more and more costly – in addition to complex logistics.

As opposed to steel, wood is a renewable material, which makes it a sound choice from the point of view of sustainability – approved by Mother Earth.
