Gaia Wind Turbines
( 1 Article )
Gaia-Wind turbines are developed and manufactured in Denmark. They incorporate more than 20 years of Danish wind industry design experience, which is the design basis for most commercial wind turbines in the market. Because of our modular manufacturing approach we are able to use components that are carefully selected to ensure the highest quality, maximum reliability and low maintenance requirements.
Key Product Features
The Gaia-Wind 11kW turbine has a wide array of features that are usually only found in larger, utility-scale machines.
They include:
Direct grid connection – the turbine is designed to connect directly to the property’s main power source, providing electricity during windy periods and drawing grid power when the wind is still. Grid connection is established with an asynchronous induction generator which eliminates the need for additional inverters.
Triple safety system – the turbine is protected against wind over speeds by a series of redundant safety measures: passive stall control; mechanical brake activation; and deployment of centrifugally activated tip brakes. These mechanisms will ensure that the rotor is ?parked? in wind speeds exceeding 25m/s (56mph).
Advanced turbine controller – manufactured by a leading manufacturer of turbine control systems, our microprocessor controller provides fully automated daily operation of the turbine. Equipped with a wide array of sensors and I/O modules, it continuously monitors and controls performance, safety and power quality conditions. Remote access and operation can be obtained through an optional software package.

Certification
Gaia-Wind is the only small wind turbine manufacturer to have achieved the Danish HB Standards. These certify compliance with rigorous quality, safety and performance requirements.
Gaia-Wind is also participating in an independent testing program conducted by the National
Renewable Energy Laboratory (NREL) in Colorado, where one of our turbines is undergoing five IEC-compliant tests. These activities will result in independently audited performance, noise, and duration data which we will add to our existing technical databases. Ongoing test results can be found on the NREL microsite.
Proven Wind Turbine Generators

When quality wind turbine energy generation is an absolute must
Global Team Direct is proud to be an authorized distributor and service provider for Proven Wind Turbine Generators. Proven Energy is the world’s leading supplier of small wind turbines. Our high performance turbines are the result of almost thirty years of inspiration, innovation and development. With over 2000 units installed worldwide, Proven Energy has unrivalled experience and has built up a global reputation for their robust and reliable performance.
Our patented Proven Flexible Blade System enables the wind turbine to generate power in light or strong winds. Our products offer sustainable energy solutions across a wide range of industry sectors, from domestic to offshore. As the wind gets stronger, the blades twist to reduce their aerodynamic efficiency. This maintains a high output even in the fiercest storms, unlike many turbines which need to stop generating power to protect themselves at high wind speeds. The blades also regulate speed, preventing damage.
Proven Energy has many years’ experience and can help you choose the right system for your needs. We offer a complete service, from site assessment and system design to supply, installation and maintenance. If you are thinking about reducing your domestic energy bills or providing a multi-site energy solution for your business, Proven Energy can help achieve your renewable energy aspirations. We make sure that your wind turbine choice will work productively for you and deliver all-round environmental benefits.

Robust
Proven Energy provides the world’s only robust, low maintenance small scale wind turbine. We work closely with clients in a number of key market sectors to make sure their specific electricity generation needs are met.
Proven Energy’s internationally patented turbine has undergone extensive testing under the most rigorous of climate conditions. Our market-leading installations operate successfully throughout the world, from Antarctica to Saudi Arabia.
Unlike upwind turbines, the system works with nature and not against it. It lets you get the most out of any wind speed, helping to maximize your investment.
Design
The patented Proven Flexible Blade System enables the turbine to generate power in light or strong winds. This unique system, a combination of innovative design and the latest techniques in advanced composite technology, allows the blades to bend and flex.
As the wind gets stronger, the blades twist to reduce their aerodynamic efficiency. This lets the Proven Energy turbine maintain a high output even in the fiercest storms, unlike many turbines which need to stop generating power to protect themselves at high wind speeds. The blades also regulate their speed, preventing damage if the load from the turbine is disconnected through a power cut or electrical fault.
Low Noise
A Proven Energy turbine is designed to minimize noise and maintenance. It has a direct drive generator, which operates without a gearbox. The generator load is continuously monitored to keep the blades rotating at a low speed, whilst optimizing power output.
Compared with other modern small turbines, the blade tip speed of a Proven Energy turbine is low. This means that noise is reduced substantially. All that can be heard is the swish of blades turning in the wind, which is virtually unnoticeable.
Low Maintenance
Proven Energy controllers are designed to run the system automatically and display power output from the turbine. The power connectors and turbine brake are easily accessible at the base of the mast.
There is no need for specialist skills. On installation you will receive an easy-to-follow user guide, which gives you all the information you need. We recommend regular maintenance checks for optimum performance. These can be carried out by a local Installer or Service Provider.
