GF 240
"Combing" in a GF 240
The furnaces in the GF75 - GF 1425 series 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 optimized 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 furnace can be rapidly warmed up. The complete firing sequence is controlled by the intuitively operated Controller P300.
