An alternative spelling for Sulfur Furnace. This furnace is used for processes involving sulfur, such as in the Claus process for recovering sulfur from hydrogen sulfide gas or for testing sulfur content. Operating at temperatures around 1000°C, it facilitates the combustion or reaction of sulfur compounds. The working principle depends on the application but often involves controlled combustion and catalysis. Its purpose is in oil and gas refineries for sulfur recovery (an environmental imperative) and in analytical laboratories for determining sulfur in various materials.
Trutherm manufactures 800 Degree Celsius (°C) Sulphur Furnace 450 x 450 x 600 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 600 MM chamber with usable chamber volume of 121.5 litre, approximate power load of 20.1 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.

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.
