Synonymous with a Dry Furnace, this unit is specifically engineered to remove moisture from materials through controlled heat application. Operating at low temperatures (around 200°C), it prevents cracking or damage that rapid, uneven drying can cause. The working principle often incorporates forced air circulation and sometimes humidity control to manage the drying rate. Its purpose is critical in preparing ceramic greenware, drying painted or coated parts, processing pharmaceuticals, and conditioning materials before high-temperature processing. It is a common fixture in industrial and laboratory settings.
This configuration is suitable when the sample load must fit a 390 x 390 x 770 MM chamber with usable chamber volume of 117.1 litre, approximate power load of 19.8 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.

Trutherm manufactures 800 Degree Celsius (°C) Drying Furnace 390 x 390 x 770 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.
