Specifications
-
Removes refractory contaminated glass at a controlled rate, without significant waste of good quality glass
-
Independent heating and cooling functions ensure that draining can be started, controlled and stopped easily and effectively
-
Individually controlled air and water cooling facilitate regulation of glass flow
-
Indirect heating removes the need to apply power through the drain tube or glass
-
No counter electrode needed
-
Low energy usage compared to direct heating designs
-
Eliminates the contamination rather than dispersing it
