Ceramic luminous radiant

Principle of the ceramic luminous radiant:

A perforated panel made of refractory materials allows an air/gas mixture to escape that then burns at the outer surface at a temperature between 750°C and 950°C.

Since the flame is visible, this ceramic panel is heated red hot, and hence the name of "luminous" radiant.

The combustion products always remain in the ambient air since such heaters cannot be connected directly to an evacuation duct.
If air renewal is insufficient, the enclosed premises must be mechanically ventilated.
