Envirotek V20 VAWT Wind Turbine

Wind energy is one of the most popular energy technologies, with the UK being the windiest country in Europe. Harnessing the natural power of the wind is essential to tackle global warming.

Envirotek are UK manufacture of low cost, high quality vertical axis wind turbines ( VAWT ).

Being small in size, they are suitable to be shipped world wide. They can provide a useful power source for small load applications including energy efficient lighting in remote areas.

Is It Right For Me?

Applications include:

Parked RVs, caravans

Boats and sailing craft.

Small cabins and farm buildings.

Remote monitoring / relay equipment.

Electric gate openers.

CONSTRUCTION
Plastic blades with aluminium frame. Stainless steel central shaft create an extremely tough storm proof vertical axis wind turbine VAWT.

GENERATOR
Robust permanent magnet alternator encapsulated inside upper compartment. Bridge diodes included producing DC.

CHARGE CONTROLLER
12V 6A charge controller (£20 extra if needed) maintains lead-acid batteries in fully charged state. Improves performance & extends life by preventing overcharging. If you have solar panels, you can integrate the V20 with the solar controller.

The installation of the unit has been made simple. The V20 comes complete with a clamping kit. This allows the wind turbine to be fitted directly to a tube 30 mm diameter.

The V20 is ideal for caravans and boats. With the V20 VAWT constantly charging the batteries, you can enjoy piece of mind knowing your electric supply is always available. Start your engine from a fully charged battery and set sail without delay!

The Envirotek V20 is a two blade Savonius type VAWT turbine. It is a safe, quiet and environmentally friendly alternative to conventional propeller type turbines. The V20 has a relative low output, designed to maintain battery charge in leisure vehicles and remote installations. Unlike solar panels and with the right conditions, the vertical axis rotor can give a 24 hour "Top-Up" charge. No more lugging heavy batteries back and forth.

How Does a Vertical Axis Wind Turbine Work?

The V20 rotates in a vertical plane driving a permanent magnet alternator. Although VAWT turbines are not as efficient as horizontal, they are virtually silent in operation and visually unobtrusive.
