Our history

In 1982, Aidro was founded by Mr. Paolo Tirelli, an Italian engineer with a vast experience in the hydraulics sector.

As a leader and innovator (patents’ inventor) in the industry, he was appointed President of the prominent hydraulics Associations (Assofluid and CETOP).

In 2004, Aidro expanded its presence with a new production plant and warehouse in Osmate (Varese).

During 2006, Aidro received the Quality Certification ISO 9001 for the design and production of hydraulic valves and components.

Thanks to the success of its activities, in 2009, Aidro established a new headquarters in Taino (Varese): a modern location, that merges high technology and art, the Aidro Founder’s passions.

In 2012, Valeria Tirelli succeeded her father as CEO of Aidro. New investments in equipments and resources were made available to the company’s clients, resulting in increased services and enlarged products’ range.
