Compared to chamber furnaces, the top hat and bottom loading furnaces are offering the advantage of convenient loading and unloading of complex charge setups on a compact footprint. The widely opening electrically or hydraulically driven hood allows for good access to the usable space. Depending on the process conditions, a top hat or bottom loading design is recommended. The system can be upgraded to include one or more tables that are manually or electrically driven. Adding further additional equipment, such as multi-zone controls to optimize temperature uniformity or controlled cooling systems to shorten process times, the furnaces can be individually adapted to the process requirements.

  • Tmax 1280 °C
  • Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
  • Top hat furnaces (model LT): Electric or hydraulic hood drive with fixed table
    Bottom loading furnaces (model LB): driven table and fixed top hat
  • Five-sided heating from all four sides and from the table provides for a temperature uniformity up to +/− 5 °C according to DIN 17052-1 
  • Heating elements on support tubes provide for free heat radiation and long service life
  • Bottom heating protected by SiC tiles with an even stacking base
  • Multi-layer insulation consisting of lightweight refractory bricks backed by special insulation
  • Long-life ceiling design with fiber insulation
  • Automatic exhaust air flap on the furnace roof
  • 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 C540 (10 programs with each 20 segments)
  • 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 documention of firings using ExcelTM for WindowsTM on the PC
  • MyNabertherm App for online monitoring of the firing on mobile devices for free download

Дополнительное оборудование

  • Tmax to 1400 °C
  • Cooling system with fresh air fan for rapid cooling
  • Sides with fiber insulation to reduce cycle times
  • Fabric cover on the fiber roof (and sides) to reduce fiber dust
  • Protective gas connection for purging the furnace with non-flammable process gases
  • Automatic gas supply systems
  • Multi-zone control adapted to the particular furnace provides model for optimal temperature uniformity
  • Commissioning of the furnace with test firing and temperature uniformity measurement (also with load) for the purpose of process optimization
  • Additional tables, table changing system, also motorized
  • Exhaust air and exhaust gas piping
  • Process control and documentation via VCD software package for monitoring, documentation and control
