RDM Rotary Distributor Leakage Detection

As rotary distributors are generally installed in locations that are complicated or difficult to access, maintenance and replacement is not always straightforward and often requires considerable effort. It is therefore all the more important to be aware of the current condition of these components. Building on experience with the CLM system, Hainzl now offers the RDM system (Rotary Distributor Monitoring), a leakage monitoring system for rotating unions.


  • Monitoring of several circuits using a single device
  • Can be used with different media
  • Alerts in the case of media mixing
  • Linked to machine controller
  • Early detection of process-related problems
