Microheaters™ - Small Scale Heaters

MHI offers a wide array of small to micro sized heating elements and tools.

MHI HeatPad MHI Igniter MHI Microfiber
MHI Microcoil MHI Microtube MHI Serpentine
MHI Spiral Microheater MHI Spiral GAXP

Standard Microheaters™ are shown below.  Custom - special orders are available for variations on many models.

All of MHI's Microheaters™ utilize the patented NanoFractalAlumina™ and Fractalins™ materials, allowing for the higher tempeartures and the corresponding energy efficent smart-device performance criterion set by MHI.   

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 , the objective of the user changes to obtain a target temperature inside the insulated region and therefore the quality of insulation matters.  For either objective, one cannot exceed the rated temperature of the heating element.  Please that the maximum temperature for any thermal device is reported at a specific region (location).   

Which Microheater™ line is best for your application?   For questions, please do not hesitate to Contact Us by email or by a call to 513-772-0404.

For obtaining the maximum rated temperature, the use of MHI controls is highly recommended.
