This furnace is designed to combust materials completely, leaving behind only inorganic ash, typically for analytical or disposal purposes. Operating around 600°C, it provides sufficient heat to oxidize all organic matter. The working principle is based on controlled combustion within a chamber, often with air flow regulation to ensure complete burnout. Its purpose is to determine the inorganic content of samples (like coal, soil, or waste) or to reduce biological waste volume safely. Commonly found in laboratories, wastewater treatment plants, and facilities handling hazardous materials, it serves critical analysis and waste management functions.
Trutherm manufactures 1400 Degree Celsius (1400°C) Ash Furnace 475 x 475 x 900 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 475 x 475 x 900 MM chamber with usable chamber volume of 203.1 litre, approximate power load of 24.8 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.
