Forced convection pit-type furnaces offer the advantage of easy charging, for heat treatment of heavy parts or loads in charge baskets. With maximum application temperatures available from 850 °C, these compact pit-type furnaces are particularly useful for processes such as tempering, solution annealing, artificial ageing, and soft annealing.

  • Tmax 850 °C
  • Air circulation fans in the furnace bottom, high circulation rate
  • Vertical air circulation with square air heating chamber
  • Temperature uniformity up to +/−  4 °C according to DIN 17052-1
  • Interior walls from stainless steel
  • Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
  • 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.
  • Defined application within the constraints of the operating instructions
  • Controller with touch operation B500 (5 programs with 4 segments each)
  • NTLog Basic for Nabertherm controller: recording of process data with USB-flash drive
  • Freeware NTEdit for convenient program input via ExcelTM for WindowsTM on the PC
  • Freeware NTGraph for evaluation and documentation of firings using ExcelTM for WindowsTM on the PC
  • MyNabertherm App for online monitoring of the firing on mobile devices for free download

Dodatkowe wyposażenie

  • Charging hoist with swivel arm and charge basket
  • Optimization of the temperature uniformity up to +/−  2 °C according to DIN 17052-1
  • Integrated fan for rapid cool down or separate cooling station for annealing box cooling outside of the furnace
  • Protective gas box/retort with protective gas inlet and outlet for production in a defined atmosphere
  • Manual or automatic gas supply systems for non-flammable protective or reaction gases
  • Process control and documentation via VCD software package for monitoring, documentation and control
