This furnace combines electric heating with a crucible container. Operating at temperatures such as 800°C, it provides a clean melting environment. The working principle uses electric elements to heat a crucible holding the charge, either from the outside or, in some lift-out designs, by lowering the crucible into a heated well. Its purpose is for small to medium batch melting of non-ferrous metals, alloys, and glass in settings like jewelry shops, dental labs, and R&D facilities, where controllability and cleanliness are prioritized.
Trutherm manufactures 1100 Degree Celsius (°C) Electric Crucible Furnace 420 x 420 x 800 MM Chamber for buyers who search by exact machine type, chamber size and 1100°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 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.

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.
