Defined by its enclosed chamber design, this furnace provides a uniform thermal environment for heat-treating batches of materials. Operating from 600°C upward, it is highly versatile. The working principle features heating elements lining all walls of a box or cylindrical chamber, ensuring minimal temperature gradients. Its purpose is for processes like annealing, hardening, tempering, and preheating of metals, ceramics, or glass. Commonly used in laboratories and small to medium-scale production, its consistent performance makes it a reliable choice for a wide array of thermal processing needs.
This configuration is suitable when the sample load must fit a 660 x 660 x 870 MM chamber with usable chamber volume of 379 litre, approximate power load of 31.9 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 900 Degree Celsius (900°C) Chamber Furnace 660 x 660 x 870 MM Chamber for buyers who search by exact machine type, chamber size and 900°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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
