Comprehensive Industrial Engineering, Automation and Turnkey Construction Solutions

About Us.

A family-owned company with more than 40 years of track record.

Today, we —the founder’s children— continue to drive this company, which has steadily consolidated its services across sectors such as bioenergy, agri-food, environmental, agroindustrial, chemical, and construction.

Our activity is based on two essential pillars: the continuous development of our people and the integration of advanced technologies to meet market demands, allowing us to accompany our clients into the already present:

INDUSTRY 4.0

Since our beginnings, we have stood out for our ability to adapt, always maintaining the reliability, quality, and professionalism that define us. The steady growth in sales and customer trust over the last decade reinforces our commitment to excellence.

We continue to work with the same dedication as in our early days: achieving our goals and offering the best to those who trust us —clients, suppliers, and partners.

Founded by Mr. José Cándido Rastrollo Díaz
