Our machines have been present in every market place or exhibition fair, first in Spain and now worldwide.
Our attendance to the places where new products and technical solutions are presented have been continuous along our history.

Since the late 70's and early 80's Infomation Technologies have been gradually incorporated to our day-to-day work. First for accounting and workforce management, second to methodize production, then as an indispensable tool for the research, design and development of our machines.

Today, our well diimensioned factory in BURCEÑA -BARACALDO, which has a well balanced and skilled staff, is furnished with state of the art machine tools and special instruments to rationally produce fans and other rotating machinery.
