Innovative Modular Wind Towers

A typical wind tower is comprised of tubular sections which are welded together. Blu-Wind's innovative design, developed in collaboration with the University of Padova, is a modular tower assembled in situ with 10.9 Friedberg bolts. A complete tower can be transported in two x 40ft standard shipping containers, which enables significant transportation savings especially in areas of Extreme Orography.

The tower, Patent No.Prot BG 2009 A 000055 guarantees power generation under the IEC 61400 specification (GL). In addition, a Blu-Wind tower’s external structure is produced with galvanized reinforced sheet-metal making it the lightest and most weather-resistant currently available.

BW/50kW Turbines

Blu-Wind srl install 20m - 50m towers for 50kW wind turbines which are suitable for communities, agricultural farms, wind farms and institutions such as schools, hospitals, local government offices, sports and leisure centres and medium sized businesses. Blu-Wind specializes in installing wind turbines for rural locations which have limited or difficult access.

Local government authorities increasingly find that the benefits of renewable energy are significant, potentially affording them financial rewards through excess energy buy-in tarifs and in some cases by reducing the tax burden on local residents. By reducing carbon emissions local communities and public sector organizations are also playing a small but not insignificant role in promoting sustainable energy.

Blu-Wind's 50kW turbines are small, efficient, quiet machines that effectively produce electricity at most wind speeds.


BW/200/250kW Turbines

The BW200/250 is a mid-range turbine produced with our German partner WTN. The BW200/250 is a gearbox turbine with three Up-Wind 13.4M blades.

Specifications:

• Blades made of re-inforced polyester and are equipped with “fail-safe” tip-brakes which are activated simultaneously by centrifugal forces.
• Blade lengths of 13.4M and a diameter of 30M
• The blade shape is constructed for high-survival wind speeds
