GRI REDUCEL (Reducel SL) is a Spanish family-owned company founded in 1955 by the Zamorano family and, since 2023, is part of GRI Renewable Industries, an integration that unites the industrial tradition of the Riberas and Zamorano families. Headquartered in Zaragoza, GRI REDUCEL specializes in the manufacture of large parts that require very high quality standards and highly specific technological processes. Its activity began with the production of gears and gearboxes under the ANZA brand, created by Antonio Zamorano. With the growth of the wind power sector in Spain during the 1990s, the company evolved toward the production of components for wind turbines, becoming especially established in the manufacture of large gears for yaw systems. In 1994, it adopted its current name, REDUCEL.
