Models  N ../45 ..  are equipped with the corresponding safety technology for drying larger and heavier charges containing solvent. As with the smaller models, the furnaces in this range can be adapted with selected additional equipment to suit the respective charge and process.

  • Furnace technology based on forced convection chamber furnaces
  • For a description of the safety technology, refer to models NA 120/45 LS ff.
  • 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 documention 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
