Benefits

  • Stable door suspension that ensures tight insulation
  • Even temperature distribution in the internal space thanks to the distribution of heating elements on all walls, including the door
  • Heated bogie with covered heat spirals
  • Top-quality insulation materials (low electrical energy consumption, option for quick run-up to the required temperature)
  • Ventilation of the operational space, preventing condensation of vapours during firing (preventing corrosion) and significantly reducing the jacket temperature
  • Programmable and highly precise temperature regulation
  • Separate limit unit that protects the furnace against damage
  • Solid state relay for smooth and noise-free operation
