Infrared oil fired heaters with separate Master burner

Infrared heaters deliver heat quickly and right where it is needed without any air movement. They are suitable for dust-free drying walls or paints, defrosting machinery or pipe lines, and heating work areas. This powerful technology results in significant energy savings and can be used in dusty areas or outside.

  • Low noise
  • Infrared heating (short wave)

  • Electronic flame control with photocell
  • Post-ventilation

Similar to the sun, short-wave infrared radiation heats the objects without heating the air. Once objects (or walls) are penetrated with heat, they can also reradiate and heat other objects. Infrared radiation heats through fog or wind. Infrared radiation travels straight, unlike hot air which rises. Infrared heaters are an excellent solution for:

  • Heating objects, bodies or walls indoors and outdoors.
  • Drying plaster walls. Infrared heat penetrates the wall and evaporates the humidity of the wall from inside. Unlike an air flow heater which creates a dry surface which traps humidity in the wall.
  • Heating objects or limited indoor spaces. Unlike other methods where the hot air is quickly dispersed in the room.
  • Saving energy, because less energy is required for achieving the same heating effect.
