ENERGY STORAGE from a purely dynamic source

You can’t reinvent the flywheel, but you can revolutionize it.

Wherever there is a need for large numbers of charging and discharging cycles,
the EnWheel® flywheel system sets new standards.

Why EnWheel® is your ideal kinetic energy storage device:

  • charges and discharges within seconds/minutes
  • virtually wear-free and maintenance-free technology
  • long-lasting capacity irrespective of the charging cycles

This makes it an efficient and clean solution for the long term.

High power. Many cycles

Speed is everything. The same applies when it comes to storing power through rotational energy. This is where EnWheel® is right out in front, at 45,000 revolutions per minute.

This has been achieved by reducing frictional losses to a minimum. The entire rotor runs in a
vacuum, on non-contact bearings and is made of carbon-fibre-reinforced plastic.

This high-tech material provides optimum strength and, as a result, allows the rotor to speed up to 45,000 revolutions per minute.

The result: a powerful energy storage device with virtually unlimited charging cycles and outstanding service life.

The DuraStor® container solution with EnWheel® storage machines

Do you want to pay for just the actual amount of electricity you use
and make optimum use of your capacities?

Then EnWheel® is the efficient storage solution for you.

Energy storage made to measure

Depending on your requirements, we equip the EnWheel® with a
motor/generator sets of different power.

For high power peaks and shorter cycle times the machine can be
equipped with a stronger motor/generator.

As modular as you want

Do you only wish to pay for the energy that you actually need?
Make optimized use of your capacities?

DuraStor® is a modular system solution in which you can increase
the number of EnWheel® machines and overall capacity at any time
to meet your needs.

Bring your cost-effectiveness up to speed with EnWheel® because efficiency
means making effective use of its capacity. Use the EnWheel®!

It's as good as already set up for you

DuraStor® is a turnkey system solution, virtually independent of local and climatic conditions.

  • Our advisers will happily identify your specific energy or storage requirements.
  • Our engineers will facilitate the entire construction and will train your employees.
