The radiant-tube-heaters work according to the radiation principle. Inside there is a tube in which a gas mixture is ignited by a low-noise special burner. As a result, radiant heat (infrared radiation) is emitted by aluminum reflectors in an extremely lightweight design. A double reflector ensures an above-average reflection rate. Corrosion protection of the blast pipes is ensured by the ALSI special coating, which offers optimum protection. The space-saving ceiling installation is optimized by the installation kit. An inclined mounting up to 30° enables an installtion near walls. Radiant tube heaters generate not only radiant heat but also secondary convection heat. This arises from the fact that heated surfaces, eg. illuminated building parts or the tubes themselves, give off the heat to the air. This can lead to a heat cushion under the ceiling, which requires the use of ceiling fans for heat recirculation for radiant tube heaters as well.
Important is the even heating of the room. An uneven placement of the radiant tube heaters leads to unheated zones, which can be compared with the shadows of the light. This underlines the ideal scope of application of this heating system. If you only want to heat individual zones of your building (eg. picking stations), radiant tube heaters are the suitable solution.
The 3-stage principle of a radiant tube heater:
Stage 1: The heat waves evolved by the radiant tube heater hit the people in the room, the floor and the objects and warm them up.
Stage 2: These heated surfaces become "secondary radiatiors" and in turn emit heat waves to the people in the room and increase the room temperature.
Stage 3: This increase in temperature transforms the surface and objects in the room into a large heating surface, which heats the air in the hall. This leads to a further increase in temperature.
