Our recommendations


Electric resistance (conduction)

Benefits

  • +High energy conversion efficiency
  • +Low specific consumption (kWh/kg)
  • +Negligible waste of material
  • +Facilitates specialty glass manufacturing
  • +Process can be automated
  • +Compact equipment
  • +No toxic gases
  • +High power density, resulting in short heating or melting times
  • +Quick fusion due to extremely high contact temperatures
  • +Production can be increased cost-effectively by adding electric resistances to existing fuel-fired melting furnaces
