Thermco’s proprietary PC-MUX is a GUI interface furnace control system running on MS Windows OS, with data collection of all main furnace parameters, which are stored in a relational database for later graphic display and analysis.

The system includes an advanced recipe editor function and Statistical Process Control (SPC) utilising reactive AI to reduce scrap events and optimise maintenance cycles by automatically analysing process runs against baseline recipes or user-defined control limits.

Process engineers can fine-tune the process performance and repeatability by use of SPC data analysis tools. Maintenance engineers can pinpoint recurrent problem events by Pareto analysis and can also predict failures before they happen by charting machine variable ‘Trends’.


  • Use statistical control to monitor and control all critical furnace parameters.
  • Finger print the best historical system performance and use this to monitor product runs ensuring a consistent high quality process.
  • Create user defined Trend charts, Overlay charts and relational databases.
  • Apply statistical analysis to determine machine process control limits for critical parameters.
  • SPC control predicts when potential problems may occur to allowing corrective action to be taken.
  • Prevents scrap process runs by highlighting process shifts.
  • Set automatic alarms and process hold limits integrated to the operations software modules to preventing committing a new product run without corrective action.
  • Pareto chart most common process alarm parameters.
  • Determine most critical process parameters using the relational database.

  • Trend chart allows the user to define a logic statements to trigger SPC analysis to specific data in the process run.
  • User set control limits (warning and hold next batch) can be applied to the trend chart over multiple runs.
  • A full suite of SPC analysis tools are availble
  • Overlay chart allows the user to characterise the response curves over a number of known good process runs. The PCMUX automatically sets control limits around the characterised baseline response curves.
  • More than one control trend chart and overlay chart can be applied to one process run.
  • Pareto chart of alarms and events to show distribution of type.
