Gaia-Wind has been developing and manufacturing small and efficient wind turbines for supplying electricity to properties such as private houses, farms, offices, companies and swimming pools for nearly 20 years. With 150 wind turbines already installed, Gaia-Wind has more than 1,000 years of operational experience.

The Gaia-Wind 133-11kW turbine has been designed to operate in environments with moderate wind and is ideal for conditions found around mainland UK, Ireland and Italy. The two-bladed Gaia-Wind 133-11kW wind turbine was developed in the early ’90s in Denmark, a world leader in wind power. The first wind turbine has been operational since 1993, representing almost 20 years of operational experience. Independent testing proves that the Gaia-Wind small wind turbine out produces equivalent three blade design

The electricity from a Gaia-Wind turbine (typically 30,000 kWh per year) delivers clean electricity for everyday use. A single Gaia-Wind 11 kW turbine will bring the carbon footprint of a four-person household back to zero.

The Gaia 133 – 11kW turbine is mounted with reflection-free light grey blades, which match the sky and the clouds. With the slimline design of the nacelle, together with its extremely low noise output, enables the wind turbine adapts easily into the surrounding countryside.

Gaia-Wind turbines have been developed according to ‘Danish design’; the design basis for most of the large wind turbines on the market. Gaia-Wind products are based on a modular design using components that have been carefully selected to provide high quality, maximum reliability and low maintenance requirements. The Gaia 133-11kW has been approved according to the official HB-standards laid down by the Danish Government. Gaia-Wind is the only manufacturer of small wind turbines to have achieved this approval, which ensures top product quality to our customers.

The Gaia 133-11kW is connected to an electrical installation at the owner’s property when a grid connection is available, thereby enabling the electricity to be used directly by the owner. Any surplus can then be sold on to the electricity board. When using stand-alone wind turbines, the turbines work in parallel with a diesel generator or a battery bank, providing clean electricity to remote installations without a public grid. Electricity from the wind turbine can also be used for direct heating purposes. Energy produced by the turbine, but not used on site, can be directed back to hot water tanks, storage heaters or under-floor heating, instead of being sold back to the electricity board.

The control system has been developed from the controllers of large turbines. It contains multiple sensors which continuously monitor the status and performance of the turbine. The internet connection for the controller means the wind turbine can be monitored online. With every Internet-connected computer or PDA, you can check the energy production and the operational status of your Gaia-Wind turbine. You will also be able to view historical production overviews.

Gaia-Wind is committed to optimising performance, safety and reliability. The Gaia-Wind 133-11kW turbine is the best performing wind turbine in its class.  The Gaia-Wind 133-11kW turbine has a swept area of 133m2. The Gaia-Wind 133-11kW turbine operates on an 18m tower.  Gaia-Wind small wind turbines also incorporate many of the safety features found on large utility-scale wind turbine farms. The Gaia 133-11kW wind turbine is protected against high wind speeds by a number of safety features: passive stall control; mechanical brake activation; and deployment of centrifugally activated tip brakes.

The Gaia-Wind small wind turbine has a patented ‘teeter’ hub which allows the two oversized blades (or one long blade) to rotate over a small angle. This prevents the most damaging turbulent loads from entering the main shaft. The two-bladed design creates greater blade stability than that shown in designs of three blades which can often suffer from high turbulent loads and increased downtime.
