Maintenance at the heart of what HYD&AU FLUID does!

Indeed, we have been using our skills to develop this activity for more than 50 years. Our expertise and know-how have led to us offering 3 types of maintenance:

  • remedial maintenance: costly for companies as it is often the result of production downtime. In this case, we perform a diagnosis, then carry out a temporary repair by replacing any faulty components. Our priority is getting your installations back up and running quickly.
  • preventive maintenance: safer for your installations, this involves carrying out regular maintenance work in order to reduce the risk of failure.
  • proactive maintenance: this is a real day-to-day approach for HYD&AU FLUID. Thanks to our experience, we have created a process to prevent malfunction before it occurs.

We have becomes masters in the operation, monitoring and performance of this type of maintenance, with clients including:

    • RENAULT for its test centres
    • PSA for its test centres
    • CETIM for its test platforms
    • ARCELOR MITTAL for its production tools
