This furnace converts organic materials (like wood, biomass, or polymers) into carbon or charcoal through pyrolysis—thermal decomposition in an oxygen-limited environment. Operating at moderate temperatures (around 500°C), it drives off volatile compounds. The working principle involves heating the material in a sealed or controlled-atmosphere retort to prevent combustion, leaving behind a carbon-rich char. Its purpose is to produce charcoal, activated carbon precursors, or carbon fibers, and is used in waste valorization and materials science. It finds applications in environmental technology, metallurgy (coke production), and manufacturing of carbon-based products.

Trutherm manufactures 1400 Degree Celsius (°C) Carbonization Furnace 125 x 125 x 250 MM Chamber for buyers who search by exact machine type, chamber size and 1400°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 125 x 125 x 250 MM chamber with usable chamber volume of 4 litre, approximate power load of 5 kW, square 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.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
