American Heat Treating (AHT) chose Super Systems Inc. (SSi) as its process-control supplier for a newly installed vacuum furnace at its Dayton, Ohio, facility. SSi supplied AHT with a new freestanding control panel containing SSI’s Series 9220 vacuum controller and SSi’s compact HMI programmable touch-screen interface. AHT plans to utilize the technology in vacuum heat treating. The 9220/compact HMI solution will provide AHT with automated process control, data acquisition with localized data logging and an intuitive user interface. The compact HMI also offers control to all I/O points, including I/O for temperatures, pumps and motors. An SSi-designed alarm system will provide AHT with an advanced notification system.
