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.
This configuration is suitable when the sample load must fit a 450 x 450 x 900 MM chamber with usable chamber volume of 182.3 litre, approximate power load of 23.7 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.

Trutherm manufactures 700 Degree Celsius (°C) Carbonization Furnace 450 x 450 x 900 MM Chamber for buyers who search by exact machine type, chamber size and 700°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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
