HYD&AU history: key dates

Acquisition of SAMELEC, specialist in electrical cabinets and industrial PLCs. The “instrumentation and control” function was incorporated into the Group, marking the start of the Automation activity alongside the historical hydraulics branch. Intragroup synergy was very quickly established with complete systems combining hydraulics and automation.

The offering changed nationally with the acquisition of FLUIDAP (hydraulics specialist) and the integration of AR TECHMAN (designer of special machines), within the Automation activity. This brought with it 9 new national locations, adding to those that already existed in the South West.

A strong desire for development was asserted and materialised through a unique and comprehensive offering of mechatronics solutions, with the aim of achieving export volumes of between 25 and 50% of the total turnover by 2020.

The hydraulics activity is structured around the HYD&AU FLUID brand. Specific regional hydraulics expertise is asserted with the specialisation of sites in different business lines. Two initial hydraulics offices offer Automation services.
