This furnace joins metal components using a filler metal with a melting point above 450°C but below that of the base metals. Operating around 700°C, it creates strong, leak-tight joints. The working principle involves heating the assembled parts in a controlled atmosphere (often reducing or inert) to prevent oxidation, allowing the braze alloy to melt, flow via capillary action, and solidify. Its purpose is to join dissimilar metals or complex assemblies where welding is unsuitable, common in aerospace, automotive, and HVAC industries for manufacturing heat exchangers, pipework, and structural frames.
This configuration is suitable when the sample load must fit a 420 x 420 x 800 MM chamber with usable chamber volume of 141.1 litre, approximate power load of 21.4 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 (800°C) Brazing Furnace 420 x 420 x 800 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.
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.
