Key Product Advantages

VAWT Benefits

• Qr6 rotor can use wind from all directions, unlike traditional HAWTs which need to track the wind – therefore maximising efficiency
• A VAWT for the same swept area has a smaller plan area than a HAWT, making it more space efficient. An important consideration when siting on or close to buildings
• The helical swept blades help distribute loads evenly, resulting in minimal vibration making the Qr6 a better option for roof mounts.

Acoustics

• The aerodynamic helical blade design results in smooth, quiet operation.
• Due to the vertical axis geometry of the rotor, the blade tips are close to the axis of rotation and travel a shorter distance per revolution. This results in a lower blade tip speed further reducing noise levels.
• Revolutionary blade tip designed to shed noise.
• Unique aero-elastic blades design captures turbulent wind and absorbs vibration.

Operating wind speeds

• The Qr6 Turbine has a cut in speed of 3 m/s (6.7 mph) and will function making a positive contribution down to 2 m/s (4.5 mph)
• The Qr6 cuts out to protect itself at 20 m/s (45mph).
• Most calm days in the UK can be considered to still have 6mph to 10mph wind speeds on the ground which increases rapidly on a mast at 15m.

Control Electronics

• The turbine is supported by a powerful industrial programmable logic controller which can easily be configured to comply with grid codes around the world.
• A three phase grid connection is required. Please contact us if you have requirements for single phase or off grid/battery version.
