GFM 420 - GFM 1050

The fusing furnaces of GFM product line were developed to meet the special requirements of production. For different applications different table models can be supplied. Standard is a table for fusing. Various tables and tubs with different heights are available as system add-ons. Especially economical is the alternating table system, in which one table is loaded while the other one is in the fusing furnace.

GF 75 - GF 1425

The fusing furnaces in the GF 75 - GF 1425 product line were conceived for professional glass artists. The heating elements, closely arranged, protected in quartz tubes, ensure a very high degree of temperature uniformity during fusing or during bending across the whole table surface. The insulation, made of non-classified fibrous material in the furnace hood and robust lightweight refractory bricks in the furnace floor allow clean and safe operation. High current connection capacities assure that the fusing furnace can be rapidly heated up.
