Gurit, a leading global supplier of composite materials and technical solutions, has secured approval from one the world’s leading certification bodies for its new blade repair system, RENUVOTM. Launched at Husum Wind Energy 2010, it has secured Germanischer Lloyd Certification (GL). Rudolf Gerber, general manager wind energy, says that “Achieving GL certification is an important milestone in the market acceptance of this new technology, which is a key component in our strategy to reduce the cost of wind energy.”
The RENUVO blade repair system offers a fresh and novel approach to the many of the practical issues that have prevented more effective and expedient maintenance programs. Addressing damage arising from production, transportation and in-field use, the RENUVO system provides the solution.A wider weather window for repair has been achieved by the working temperature range starting at +5ËC. Traditional wet laminating materials must normally be used above +15ËC as they can suffer from bi-product and handling issues. Summer- and winter-grade versions of the RENUVO MPS (Multi-Purpose System) and RENUVO PP (Prepreg) are available to cope with most conditions.
The RENUVO product range has transformed the conditions for repair by using UV light from the RENUVO lamp technology to cure materials in minutes. A spot lamp is available for simple maintenance repairs with a higher intensity product available for deeper structural repairs using RENUVO PP. Both lamps are available exclusively from Gurit. Benefits include: over 50 percent reduction in structural repair time; low odor, zero VOC resin; styrene and amine-free; extended weather window for repair from +5ËC; zero post-cure for repair; and compatibility with all types of blade construction including prepreg, epoxy infusion, and polyester infusion. The Certificate is published on the Germanischer Lloyd Web site. Also visit www.gurit.com.
