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 fiber 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.

• Other sizes or custom designs available on request
• Exhaust air flap on hood for rapid cooling as additional equipment

The GFM series was developed to meet the special requirements of production. Depending on the application, different tabletop and tub systems are available for delivery. A movable table system on castors is supplied as a standard for fusing applications. Various tables and tubs with different heights and numerous additional equipments 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 furnace.

Product Advantages GF and GFM

Well-dimensioned quartz glass heaters provide for a very even temperature uniformity on the glass.

Sturdy design of brick insulation results in a solid flat table top.

Insulation of the table collar made of long lasting light-weight refractory bricks.

Solid state relays to switch the heating elements which results in an optimal adaptation of the firing cycle to the temperature curve.

Flaps with inspection glass as additional equipment for easy observation of the glass.

Large metal handle for opening and closing of the kiln.

Insulated gas dampers result for easy opening of the kiln.

Hood with exhaust air flap as additional equipment.

Base on castors with shelf for tools or other materials.

Automatically driven lid as additional equipment.

This well-priced kiln range is the ideal choice for many fusing applications. The insulation is made from lightweight refractory bricks with protected heating elements in the lid, models F 75 and F 220 have additional side heating.
