The objective of the use of free radiating devices is to maximize the RADIATIVE POWER transfer from the heating elements.  If the heating element is used with an insulation cover, the objective of changes to obtain a target temperature,  inside the insulated region.  For either objective, one cannot exceed the rated temperature of the heating element.  Please note that the maximum temperature for any thermal device is reported at a specific region (location).

Microheaters are useful in a variety of applications such as materials processing heating and deposition including additive manufacturing, targeted heating for stress relief including fiber-joining, channel heating, automotive plates, engine heating in cold climates, ship instruments, space heating and propulsion and many more…

New –   high power density, high temperature “spot radiators”.
