ELLE™ Leading Edge Protection
ELLE™ Leading Edge Protection

Retrofit leading edge protection for all turbines

It is never too late. Retrofit leading edge protection for your wind turbine blades will reduce your operating costs, improve the levelized cost of energy (LCoE), and significantly enhance your blade performance. Top that with a solution that is designed to protect for a lifetime, and you get ELLE™-Everlasting Leading Edge.

Leading edge erosion is not going anywhere

As rotor blades get longer, the tip speed of the blades becomes faster. And with wind turbines being erected in ever-tougher and increasingly remote locations — including offshore sites — this only makes leading edge erosion more of a problem. A forecast by the energy consultancy Wood Mackenzie projects that, by the end of the decade, the money spent repairing leading edges will surpass one billion dollars per year.

 

Leading edge protection that lasts – here comes ELLE™

Following intense product development and thorough field and lab tests, in 2017 we unveiled a brand-new type of protection: ELLE™ – Everlasting Leading Edge. As the name suggests, ELLE™ was built to last the lifetime of your turbine.

 

 

What our customers say

 

It consists of pre-cast sections made of robust yet soft and flexible polyurethane shells. The shell’s surface is designed and dimensioned to absorb the kinetic energy from rain, hail, and airborne particles. As such, the shell provides optimal protection for the rigid fiberglass surface of the blade.

 

With ELLE™ you will save repair and replacement costs, and improve your energy production costs by preventing damages at all scales that would otherwise lead to poorer aerodynamic performance and structural instability.

 

Convenience and simplicity in focus

As there is no time to waste when it comes to protecting your blades, we made sure that not only can ELLE™ be applied during manufacturing, but can also be retrofitted to your installed base. We also know that installations might be postponed at the very last minute due to e.g. bad weather. But no need to worry. We designed ELLE™ with a wide application window. The shell pattern is also custom-made for each individual blade to ensure an optimal fit on your blades. In short, when it comes to ending leading edge erosion, nobody does it better than ELLE™.
