Free Radiating Heating Coil - MagnaCoil™

For Heavy Industrial Use Made Possible With MHI Patents On Nanomaterials

MagnaCoils™ - 1450°C Maximum Surface Temperature of Coil.  The objective for the use of free radiating devices is to maximize the radiative POWER transfer from the heating elements.

If the heating element is used with insulation the objective of the user changes to obtaining a certain temperature inside the insulated region.

For either objective, one cannot exceed the rated temperature of the heating element (coil). The element use temperature may be further limited by creep and stress conditions including creep-fatigue interactions. Although general guidance on use is given, specific conditions are not known to MHI.  Users are cautioned to use appropriate safety factors for the use- temperature rating.

If an insulated coil is preferred please see our Robust Radiator™ line of products now available with fiberfree™ high quality refractory enclosure.

Please use MHI Power Controls for the best performance.  Please use Robust Raditors if using at the limit of performance.

Vertical configuations and/or stress wmay reduce the use temperature. 

CHS-OD or equivalent spacers recomended when creep is possible.
