This furnace uses a bath of molten salt (like chloride or cyanide salts) as the heating medium. Operating at temperatures such as 600°C, it provides extremely rapid and uniform heat transfer. The working principle involves immersing parts directly into the molten salt, which heats them quickly and evenly from all sides. Its purpose is for quenching, austempering, martempering, and annealing of tool steels and other alloys, as well as for cleaning and descaling. It offers precise temperature control but requires careful handling of the molten salt and its fumes.

Trutherm manufactures 1400 Degree Celsius (°C) Salt Bath Furnace 250 x 250 x 500 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 250 x 250 x 500 MM chamber with usable chamber volume of 31.3 litre, approximate power load of 11.6 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.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
