qr5 turbine details

The qr5 was designed in response to increasing demand for wind turbines that work well in environments close to people and buildings.

The elegant helical (twisted) design of the qr5 ensures a robust performance even in turbulent winds. It is also responsible for virtually eliminating noise and vibration.

At five metres high and three metres in diameter, it is compact and easy to integrate, and with just one moving part, maintenance can be limited to an annual inspection.

Clients include major retailers, developers, government departments, schools and universities.

Three ‘S’ shaped blades are tapered to shed noise

The vertical axis is easy to integrate with existing masts and buildings
The helical (twisted) design captures turbulent winds and eliminates vibration
The blades, spars and torque tube are made of robust carbon fibre, and all moving parts are sealed to minimise maintenance
The direct drive in-line generator has auto-shutdown and peak power tracking and is incorporated into the mast

UK design and patent protected. Patent pending in additional global territories.

When considering installing a turbine a customer should consider the following:

  • Vibration – we have researched this issue in depth and deploy systems to reduce vibrations to levels that are not measurable within the building.
  • Aesthetics
  • Safety – we deploy a dual braking system and various sensors to detect faults / out of balance/ impact / vibration etc.
