Infrared micathermic heaters

Micathermic

— a heating element in the form of a metal plate covered on both sides with a layer of material that is an electrical insulator and at the same time does not retain IR radiation (the ideal version of such a material is mica). The key difference between micathermic elements and the types of heaters described above is that they intensively emit thermal energy without heating up to high temperatures. Due to this, heaters with such elements have a high efficiency with a minimal risk of fires and burns during use. In addition, metal plates are noticeably stronger and more reliable than glass tubes in other types of heaters. Among the disadvantages, it can be noted that the plates are usually covered with a fairly fine grid, in which dust tends to accumulate.
Note that some manufacturers also classify heaters with a traditional quartz tube as micathermic, which use special technologies to increase heating efficiency. Such models can be identified by their appearance: the quartz tube glows during operation, unlike the micathermic plate.
