CSN® air heater type 800

Series 800 air heaters are electric heating coils for air ducts, especially for drying systems and industrial process applications. They consist of CSN® heating grids that are robustly mounted.


Series 800 industrial air heaters are the ideal solution for heating gaseous media. Our electric air heater is equipped with a high-quality heating element made of CSN® heating grids, which are resistant to vibration and impact even at air velocities of up to 10 m/s and overpressures of up to 10 mbar.

Product advantages

  • Heating grilles made of temperature-resistant ceramic or glass fibre
  • Direct and immediate heat transfer from CSN® heating grids to the medium
  • Precise temperature monitoring using PT100, thermocouples, controllers, monitors and limiters
  • Lightweight design, non-drilled flange frame connection
  • With optional fan
