The fusing furnaces in the GF 75 - GF 1425 series are designed for professionals. Closely arranged heating elements protected in quartz glass tubes ensure very good temperature accuracy during fusing or bending on the complete area of the table. All models have an appealing, dual-shell stainless steel housing. The level table surface made from rugged, durable refractory material and the lid opening with gas pressure springs as support simplify charging of the furnace. The optimized electrical connected load ensures that the glass heats up quickly. 

• Tmax 950 °C, GF 75: Tmax 900 °C
• 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
• Dual shell hood made of stainless steel with slotted cover lid
• 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 insulated with high-quality fiber material; exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
• Adjustable, large quick-release fasteners - can be used while working in gloves
• Handles on the left and right side of the hood for opening and closing the furnace
• Hood safety switch
• Solid state relays provide for low-noise operation
• Rapid switching cycles result in precise temperature control
• Type K thermocouple
• Hood easy to open and close, supported by compressed-gas springs
• Lockable air inlet opening for ventilation, fast cooling and observation of charge
• Robust base on rollers (two of them can be locked down) with tray for glass and tools
• 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
• Controller C540 (10 programs with each 20 segments)

• Motorized lid opening for faster cooling for models GF 380 up
• Bottom heating for uniform through heating of large objects
• Cooling fan for accelerated cooling with closed lid
• Motorized exhaust air flap for faster cooling of the fusing furnace
• Air inlet flap with window for observing the glass
• Process control and documentation via VCD software package for monitoring, documentation and control
