Tank Furnaces for Optical Glass

Technical Data:


Melting area:                   1-5 m2

Melting capacity:             500 kg/d – 4t/d

Platinum-refining cell:      dependent on melting capacity

Batch charger:                 piston- or  spoon-charger


  • suitable for low melting capacity with highest glass-quality
  • suitable for melting of different optical glasses 

This type of furnace is gas- and electrical heated and are equipped with the latest platinum-technology. The melting- and refining-part are two separate units. The batch is melted with a gas-/electrical-heating in the melting part and after that it is refined in the platinum-refining cell.

The requirement of precious metals is approx. 50 - 200 kg, depending on melting capacity.
