Maximize the lifetime of your turbines

GR400 and W100 increase operating smoothness and reduce wear on wind turbine gearboxes and bearings

REWITEC products extend the service life of wind turbine gearboxes and bearings, removing and repairing previous surface damage, and generating positive impact which is clearly visible on Condition Monitoring Systems (CMS).

W100
Coating Concentrate for Turbine Gears

DuraGear W100 is specially developed for the wind industry to extend the life of all moving parts right through to the scheduled re-powering, without having to make additional investment in a gearbox. Consequently, the replacement of a gearbox can be better planned and moved to a windless period.

GR400
Grease Additive for Turbine Bearings

GR400 is a special additive for turbine grease applied to pitch, generator and main bearings and azimuth and pitch gears. It’s patented silicate formulation improves stressed systems: components benefit from surface refinement, and damage can be prevented even in recently-installed systems.

Our products have many uses.

Ideal installation of REWITEC products is 3-7 years after turbine installation, before the impacts of severe wear and tear affect turbine performance and shorten turbine life.

REWITEC products can be used not only in main bearings and main gears but also in other areas of a wind turbine. These include the generator bearing, azimuth gears, pitch gears and the pitch bearing.
