GFM 420 - GFM 1050

The GFM product line was developed to meet the special requirements of production. For different applications different table depths can be supplied. Standard is a table for fusing. 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.

• Tmax 950  °C
• Infrared heated in hood which is attached to stand
• Delivered with one table
• Table on wheels, freely movable
• Level table surface with insulation made of robust lightweight refractory bricks and marked charge surface
• Comfortable charging height with base of 870 mm
• Heating element, protected in quartz tubes
• High current connection capacities for short warm-up times and energy-saving way of working
• Arranged closely beside each other on the top, heating elements ensure direct and uniform radiation of the glass
• Solid state relays provide for low-noise operation
• NiCr-Ni thermocouple inside the furnace for precise temperature measurement
• Dual shell housing, adjustable hood made of structured stainless steel with lid made of perforated sheet metal
• Hood insulation made of non-classified ceramic fibers for rapid heating up and cooling down
• Attractive design and solid construction
• Hood very easy to open and close, supported by high-quality compressed-gas springs
• Adjustable, large quick-release fasteners - can be used while working in gloves
• Supply air and glass inspection ports with insulated doors, viewing window as an additional equipment
• Defined application within the constraints of the operating instructions

Additional features for fusing furnaces GF and GFM

• Motor-driven lid opening for faster cooling, programmable via the extra controller function, for models GF 380 and/or GFM 380 up
• Bottom heating for uniform through heating of large objects as additional equipment
• Cooling fan for accelerated cooling with closed lid
• Additional tables for extension of the furnace system
• Exchangeable table system for utilization of the residual heat of the furnace. Cycle times can be shortened by changing the tables in warm condition (depending on the ability of the respective glass to cope with temperature change)
• Exhaust air flap on hood for rapid cooling
• Air inlet flap with window for observing the glass
