The REWITEC technology for wind turbines has been scientifically proven and reduces friction and wear of gears and bearings. The surface treatment significantly increases the service life and energy efficiency; for example standstill damage and micro pitting can be frozen or even repaired. Sentient Science came to the conclusion that the use of DuraGear W100 can increase the service life by a factor of 2.6 for bearings and 3.3 for gearboxes.
