PLC Based Combustion Control Systems

For more sophisticated burner control logic we offer PLC based combustion control and HMI interfaces. These systems are designed to work in conjunction with our standard or PLC burner management packages.

  • Improved Process Control & Operational Efficiency
  • Advanced Data Communications
  • Functions for maximized burner fuel efficiency such as fully metered, cross-limited combustion control, oxygen trim, and ambient temperature compensation
  • Lead-lag burner control for multi-burner systems
  • Enhanced operator interface display via large touch screen HMI
  • Pre-programmed recipes & cycles specific to site requirements
  • All systems are completely functionally tested prior to shipment in our UL listed assembly facility
