Annealing furnace GR 1300/13

heatinglaboratorystainless steel

Overview
The furnace chamber of the gradient furnace GR 1300/13 is divided into six equal control zones with separate temperature control. The unit can operate as a gradient furnace or, on request, as a lab strand annealing (tunnel) furnace with a second door. Maximum stabilizable temperature gradient is 400 °C over the heated length of 1300 mm. Charging is possible from the side via the parallel swing door or from the top when using the supplied fiber separators.

Standard equipment

• Tmax 1300 °C
• Heated length: 1300 mm
• Heating elements mounted on support tubes for free radiative heating
• Dual-shell housing in textured stainless steel with additional fan cooling for low external surface temperature
• Insulation materials without classification under EC Reg. No. 1272/2008 (CLP)
• Top charging or side charging via parallel swing door
• Gas damper-assisted lid suspension
• Separate control of six heating zones (each 160 mm)
• Temperature gradient up to 400 °C across the heated length
• Fiber separators partitioning the chamber into six equal compartments
• Controller H1700

Additional equipment

• Up to ten control zones
• Second parallel swing door for lab strand (tunnel) operation
• Vertical strand furnace configuration
• 1400 °C version (on request)
• Process control and documentation via VCD software package
