  • For installation in the forehearth conditioning section
  • Proven for effectively removing side to side and top to bottom glass temperature differences
  • Particularly useful in wide forehearths or coloured glass production
  • High installed total power allows quick reaction to changing forehearth conditions
  • Multiple power zones and flexible configurations allow system operation to be tailored to suit individual job parameters
  • Proven installation techniques allow system to be added during operation without the need for draining or cooling down the forehearth
  • Automatic power/temperature and manual control facility for each heating zone
  • Utilises Electroglass’ special design dry electrodes to ensure consistent glass quality without risk of induced DC voltage, a problem common with some other designs
  • Low operating power, typically only a few kilowatts
