This furnace is specifically for hardening ferrous metals, particularly steel, by heating them to a critical temperature (typically 850°C for many steels) and then rapidly quenching in oil, water, or polymer. The working principle involves a chamber that heats the parts uniformly to the austenitizing temperature, followed by a quick transfer to a quench tank. Its purpose is to increase the hardness and wear resistance of components like tools, gears, and bearings. It is a fundamental piece of equipment in heat treatment shops and manufacturing plants.
This configuration is suitable when the sample load must fit a 875 x 840 x 840 MM chamber with usable chamber volume of 617.4 litre, approximate power load of 38.9 kW, rectangular - wide 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 1100 Degree Celsius (°C) Hardening Furnace 875 x 840 x 840 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.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
