Eolienne 2,5 Kw

The ANTARIS wind turbine is a wind energy system that is ideally suited to inland sites. It is designed specifically for feeding power into the grid, charging batteries (24 V / 48 V etc.) and for supporting heating systems.

Thanks to its extremely robust and well thought-out design the ANTARIS wind turbine system is also suitable for stormy regions, with different optional repeller diameters (2.30 - 6.40 m).

The hand-laminated repeller blades benefit from a computer-designed aerodynamic profile. Needless to say, each blade is statically and dynamically balanced, carries an identification number and comes with relevant documentation.

The drive system of the ANTARIS small wind turbine system follows a simple logic: Fewer rotating components reduce the mechanical load and increase the technical operating life.

The maintenance and servicing is reduced (including less wearing parts, no gearbox oil change) and the operating costs drop.  The rotor hub and permanent magnet generator are directly connected together as a fixed unit without gears. The rotor unit is mounted on a rotating axis with a high-strength material. In comparison with conventional gearing systems with numerous bearings in the moving drive train the ANTARIS operates with two relatively slow running rolling-contact bearings.

The same applies for the tilting unit, which is only activated by the wind and thus operates absolutely free of wear. For safety the ANTARIS has two high-quality stainless steel mufflers installed, which protect the corresponding end stops. The steels used are all provided with a test certificate, which documents the grade of the steel.

The welding joints are only carried out by certified welders. After the blanks have been manufactured all steel parts are galvanised under high temperature. This galvanising process has significant advantages for corrosion protection compared to conventional (hot-dip galvanisation) galvanisation processes. With the high-temperature galvanisation we offer you the most effective method for protecting all parts against corrosion that are responsible for safety and operation under taxing demands of the elemental weather conditions.
