DM 30 - DM 40 - DM 50

Multiprogram pre-heating furnaces


  • The pipe heating system is more efficient compared to the traditional muffle system
  • Low energy consumption
  • Greater dependability over time
  • Lighted LED display makes using this machine quick and easy
  • Possibility of modifying a program while is running
  • 1-year warranty


  • Pipe heating system: the resistors are housed inside the refractor pipes
  • Electronic microswitch: detects the opening of the hatch, interrupting the power supply to the resistors
  • Preset aspirator command to allow release of fumes
  • Possibility of memorie up to 10 different cycles each with up to 4 positions
  • Electronic temperature control with microprocessor  allows the following parameters to be set for each program:
    • temperature
    • maintenance temperature
    • Speed at which temperature rises (expressed in °C/min)
    • Extractor OFF temperature 
  • Automatic management of the extractor depending on program
  • Delayed start with the possibility of setting the day and time of furnace activity
  • Maximum working temperature 1100 °C
