A general furnace for burning off residues from materials, containers, or tooling. Operating around 600°C, it is used for cleaning and recovery operations. The working principle provides a high-temperature environment to oxidize organic residues into ash and gases, which can be vented away. Its purpose is to clean crucibles, remove paint or coatings from metal parts, clean industrial filters, or reclaim valuable components from composite materials. It is a utility furnace common in maintenance departments, recycling facilities, and laboratories.

Trutherm manufactures 800 Degree Celsius (°C) Residue Furnace 450 x 450 x 900 MM Chamber for buyers who search by exact machine type, chamber size and 800°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 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.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
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.
