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
- Dual shell housing made of textured stainless steel sheets with additional fan cooling for low surface temperature
- Exclusive use of insulation materials without categorization according to EC Regulation No. 1272/2008 (CLP)
- 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
- Defined application within the constraints of the operating instructions
- Controller H1700
Process Control and Documentation
As one of the world’s largest furnace manufacturers, Nabertherm has many years of experience in the design and manufacture of standardized and customer-specific control systems. All controls are characterized by a very high level of operating convenience and even the basic version has extensive basic functions. Depending on the requirements, the functions can be expanded and adapted to your needs. Professional software solutions for single or multiple furnace management as well as process and batch documentation based on our Nabertherm controllers complete the range.
Also for compliance with industry-specific standards that define process control and documentation, such as for example, the AMS 2750 F for aviation, the CQI-9 in the automotive industry or the FDA in the pharmaceutical industry we offer standardized solutions.
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
- Process control and documentation via VCD software package for monitoring, documentation and control
