Specifications
-
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
