This furnace performs heat treatment on materials that require processing at the upper end of the temperature spectrum, e.g., above 1000°C. It is used for high-alloy steels, superalloys, and refractory metals. The working principle includes precise atmosphere control (often vacuum or inert gas) to prevent scaling or decarburization at these aggressive temperatures. Its purpose is to develop the unique high-temperature strength and creep resistance needed for components in jet engines, power generation turbines, and high-performance racing engines.

Trutherm manufactures 1100 Degree Celsius (°C) High-Temperature Heat Treatment Furnace 400 x 400 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 400 x 400 x 800 MM chamber with usable chamber volume of 128 litre, approximate power load of 20.5 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.
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.
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.
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.
