  • Fully automated SCADA systems with enhanced reporting and data collection capabilities.
  • Austempering, carburizing, martempering and neutral and case hardening capabilities.


CAN-ENG also offers Continuous Mesh Belt Furnace Systems Energy Reduction Systems (ERSTM). ERS technology reduces the overall energy requirements, while maintaining the systems output capacity and product quality. There is a 20% reduction of overall CH4 consumption compared to conventional mesh belt systems. A newly developed atmosphere recovery system reintroduces the heat source to the incoming product prior to entering the furnace. Continuous preheating of in-going belt and work allows for energy recovery prior to entering the furnace. The specially designed self recuperative burners integrate high-velocity flue gas recirculation lowering NOx levels up to 50%. Waste heat is reintroduced to auxiliary equipment for improved system efficiency. Reduced heating times allow for additional production capacities.


Continuous Mesh Belt Atmosphere Heat Treat System processes include:

  • Annealing
  • Austempering
  • Carbon Restoration
  • Carbonitriding
  • Carburizing
  • Case Hardening
  • Iso-Thermal Annealing
  • Martempering
  • Neutral hardening
