  • 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
  • No wall cooling or electrode changing required
  • Programmable CNC-controlled batch charging system on most furnaces
  • Critical equipment, such as control panels, electrode holders, batch chargers, designed and manufactured in-house
  • Choice of control systems using advanced PC/PLC technology and user-friendly software with options to suit particular customer requirements
  • Individual physical modelling and design studies carried out for each furnace project
