The furnace chamber of the gradient furnace GR 1300/13 is divided in six control zones of equal length. The temperature in each of the six heating zones is separately controlled. The gradient furnace is usually charged from the side through the parallel swivel door. A maximum temperature gradient of 400 °C can then be stabilized over the heated length of 1300 mm. On request the furnace also is designed as a lab strand annealing furnace with a second door on the opposite side. If the included fiber separator are used charging is carried-out from the top.

Standard Equipment:

• Tmax 1300 °C
• Heated length: 1300 mm
• Heating elements on support tubes providing for free heat radiation in the kiln chamber
• Charging from the top or through the right side door
• Gas damper suspension of the lid
• Separate control of heating zones (each 160 mm long)
• Temperature gradient of 400 °C over the entire length of the kiln chamber, each zone can individually be controlled
• Fiber separators dividing the chamber in six equally sized chambers
• Controller H1700, alternative controllers available on request

Additional Equipment:

• Up to ten control zones
• Second parallel swing door for use as lab strand annealing furnace
• Vertical instead of horizontal strand furnace
• 1400 °C model

*This is designed to be a representation of the features available for this range. For more technical information and information on additional equipment please consult the brochure and reach out for a quote. This furnace features no safety technology for processes which produce combustible mixtures, for example debinding. If the furnace is still used for such processes despite this fact, the concentration of organic gas mixtures in the furnace must never exceed 3% of the lower explosion limit (LEL). This pre-requisite applies not only to normal operation but, in particular, to exceptional situations such as process disruptions (caused, for example, by the failure of a power unit). You must ensure that the furnace is adequately ventilated and vented. *
