A general, abbreviated term for a Heat Treating Furnace. It is a versatile furnace used for annealing, hardening, tempering, and normalizing metals. Operating from a base of 600°C, it is a broad category. The working principle involves controlled heating and cooling cycles within an insulated chamber to achieve desired metallurgical transformations. Its purpose is to tailor the mechanical properties of metal components across virtually every heavy and precision engineering industry. It is the backbone of metallurgical processing.

Trutherm manufactures 1300 Degree Celsius (°C) Heat Treat Furnace 225 x 375 x 225 MM Chamber for buyers who search by exact machine type, chamber size and 1300°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
This configuration is suitable when the sample load must fit a 225 x 375 x 225 MM chamber with usable chamber volume of 19 litre, approximate power load of 9.5 kW, rectangular - tall chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.
A muffle furnace isolates the sample from direct contact with heating elements or combustion gases, giving cleaner, more repeatable results than an open flame or hot-plate process.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
