The origin of this concept dates back to 2006, when Mr Montaner designed and patented (no. WO2006111597, US7770343-B) the first 120 m high hybrid tower for one of the biggest wind turbines in the market, the GAMESA G10- 4.5 MW with ∅120 m rotor diameter. The tower was firstly installed in 2008 in Jaulín (Zaragoza), SPAIN, and since then 8 more units have been assembled in Spain. The tower was fully monitored with over 200 instrumented measurement points.

During the construction of this first hybrid tower, Mr Montaner foresaw the challenge that wind energy will have to face: the construction of taller towers (> 140 m) where traditional steel tower technologies and installation means could not reach. Based on the expertise gained through decades in precast concrete, HWS presents the solution to this problem: the AirTOWER. 

The AirTOWER is a super-tall precast concrete tower that enables reliable, cost-effective, and environmentally friendly installation of new generation onshore wind turbines (>5 MW) at heights above 140 m.

Combining it with the self-climbing AirCRANE, the system becomes unbeatable and reaches theoretical infinite heights.
