600 Pipes. 127 Heat Exchangers. One Model That Matches Reality.

 Hydrus Works used Fathom to calibrate a complex refinery cooling water system to within ±4.8% flow and ±1.8 psi—and turned it into a permanent operational asset. 

 Recalibrating a system this large requires more than a good model -- it requires one you can trust. Hydrus Works used Fathom's Scenario Manager, Goal Seek and Control, and custom Python tools to align 700+ field measurements against a fully calibrated model. The result isn't just a deliverable. It's a living asset engineers keep using. 

  • Flow accuracy within ±4.8% and pressure accuracy within ±1.8 psi across the full system
  • 700+ field measurements used to ground-truth model against real operating conditions
  • Python-integrated workflows automated K-factor calculations and cut manual engineering time
  • Model now supports ongoing troubleshooting, planning, and system optimization
