Specifications
-
Capacities from 200 kg/day to over 250 tonnes/day
-
Cold-top melters with superstructure temperatures typically less than 125 deg.C
-
Exceptionally low energy consumptions, usually 20% to 40% less than other designs
-
Negligible volatilisation and consistent thermal history mean high glass quality
-
Minimal environmental pollution, even from volatile glasses
-
Silent operation
-
Flexible operation with turndown to 50% of rated output or less
-
Ability to withstand long power interruptions without emergency measures
-
Even energy distribution for minimum refractory-glass contact temperatures and low refractory wear
-
Uniform refractory wear pattern and extended furnace life
-
Short cold repair time for maximum productivity
-
Low cold repair costs: glass contact equipment and substructure refractories only
