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.
This configuration is suitable when the sample load must fit a 900 x 610 x 610 MM chamber with usable chamber volume of 334.9 litre, approximate power load of 30.4 kW, rectangular - wide 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.
Equivalent chamber references: 900 x 610 x 610 MM, 90 x 61 x 61 CM and 36 x 24 x 24 INCH.

Trutherm manufactures 800 Degree Celsius (°C) Residue Furnace 900 x 610 x 610 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.
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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
