The Future of Exchanger Tube Cleaning

Experience the future of industrial cleaning with Sentinel, the ultimate automation technology platform that seamlessly integrates with StoneAge's AutoBox 3L and 1L tube cleaning systems.

Our latest release, Sentinel Operating System 2.0, takes your cleaning operations to new heights with streamlined job setup, onscreen tubesheet visualization, automatic learning functions, and predictive job data. Unlock unparalleled efficiency, precision, and consistency in your cleaning processes with Sentinel 2.0.


  • AUTONOMY MODE: Sentinel identifies the boundary of the tubesheet during setup, then predictively diagrams and cleans the remaining interior tubes automatically.
  • TUBESHEET VISUALIZATION: The controller now displays a real-time visual diagram of the tube sheet, enabling efficient cleaning without requiring a direct line of sight.
  • JOB CAPTURE: Save the job-specific tubesheet diagram generated by Sentinel, and re-load it for full automation the next time the bundle is cleaned.
  • OBSTACLE AVOIDANCE: Sentinel can automatically steer around plugged tubes and other obstructions during cleaning, preventing equipment damage.
  • AUTOMATIC LEARNING FUNCTION: Sentinel can now learn the pitch and pattern of tubesheet without requiring the operator to make manual measurements. No need for P&ID from the plant to begin the job.
  • STREAMLINED JOB SET UP: System setup has been simplified to a few guided steps, enabling operators to get up and running quickly and successfully.
  • PREDICTIVE JOB DATA: Estimate "time until completion" based on cleaning rate and tube count.
  • UNIFIED OPERATING SYSTEM: Use the same controller and software for both 3L and 1L Sentinel systems.
