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.

  • 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
  • Infrared heated in top hat which is attached to stand
  • Dual shell top hat made of stainless steel with slotted cover lid
  • Delivered with table
  • Table on wheels, freely movable
  • Controller integrated to save space on the right side of the furnace
  • Level table surface with insulation made of robust lightweight refractory bricks and marked charge surface
  • Top hat insulation made of non-carcinogenic fiber material for rapid heating up and cooling down
  • Adjustable, large quick-release fasteners - can be used while working in gloves
  • Handles on the left and right side of the top hat (from model GFM 600 also in the middle) for opening and closing the furnace
  • Top hat safety switch
  • Solid state relays provide for low-noise operation
  • Type K thermocouple
  • Top hat easy to open and close, supported by compressed-gas springs
  • Lockable air inlet opening for ventilation, fast cooling and observation of charge
  • Comfortable charging height of 860 mm
  • Defined application within the constraints of the operating instructions
  • NTLog for Nabertherm controller: recording of process data with USB-flash drive

Additional features for fusing furnaces GF and GFM

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-carcinogenic fiber material in the furnace top hat 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.
