Due to their very good temperature uniformity, these chamber furnaces with air circulation and safety equipment based on EN 1539 Type A are especially suitable for processes such as drying paints or components with residues of flammable cleaning agents or the evaporation of solvents bound in the components.

  • Design based on forced convection chamber furnaces
  • High-powered heating to maintain the required air exchange rates
  • Powerful exhaust air fan to ensure underpressure in the furnace
  • Defined and monitored air circulation and exhaust air
  • Visual and audible malfunction signals
  • Over-temperature limiter with manual reset as over-temperature protection for the furnace and the charge
  • 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 P570 (50 programs with each 40 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 documentation of firings using ExcelTM for WindowsTM on the PC
  • MyNabertherm App for online monitoring of the firing on mobile devices for free download

Additional equipment

  • EN 1539 with reduced exhaust air flow rate to 25 % after the main evaporation time to save energy
  • EN 1539 with temporary switching off for processes in which no flammable substances are released
  • Process control and documentation via VCD software package for monitoring, documentation and control
