GF 75 - GF 1050

Models in this range include the GF 75, GF 75 R , GF 190, GF 240, GF 380, GF 420, GF 520, GF 600, GF 920 and GF 1050.

The furnace models GF 75 - GF 1050 are particularly suitable for fusing of glass. Their special construction, with infrared heating elements mounted on the ceiling and light fibre insulation, ensures fast heat-up and cool-down rates and optimum fusing or slumping results.

As protected infrared heating is used, any direct contact with the heating coils is avoided. This means you can safely open the furnace during operation without the need to switch off the heating.
