This furnace is designed for the low-temperature drying of materials, typically operating around 200°C. Its purpose is to remove moisture, solvents, or other volatiles without causing thermal degradation. The working principle involves circulating heated air within an insulated chamber to ensure uniform drying. It is used for pre-drying ceramic molds, curing coatings, drying laboratory samples, or removing moisture from electronic components. Unlike higher-temperature furnaces, its design prioritizes precise low-temperature control and often includes ventilation for vapor removal.
Trutherm manufactures 800 Degree Celsius (°C) Dry Furnace 900 x 850 x 850 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.

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.
