This is a large, heavy-duty version of the standard box furnace, designed for industrial-scale batch heat treatment. Operating at temperatures like 600°C and higher, it handles substantial loads. The working principle is scaled up, with powerful heating systems, robust insulation, and often automated door systems and material handling. Its purpose is for annealing, normalizing, tempering, and stress relieving of large metal parts or large batches of smaller parts in industries like forging, casting, and fabrication. It is valued for its durability and capacity.

Trutherm manufactures 1100 Degree Celsius (°C) Industrial Box Furnace 810 x 810 x 900 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 810 x 810 x 900 MM chamber with usable chamber volume of 590.5 litre, approximate power load of 38.2 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 annealing, tempering, hardening and general heat-treatment of metal and ceramic parts in tool rooms, forge shops and QC labs.
Because the chamber geometry is simple, box furnaces are typically the most cost-effective furnace type per litre of usable volume, which is why they remain the default choice for general heat treatment.
Door seal quality and insulation thickness directly affect heat-up time and running cost, both of which are sized to the chamber volume on this model.
Compared to a tube or ashing furnace, this box (chamber) furnace gives the largest usable loading footprint for its outer size, so it suits irregularly shaped parts, trays and multiple crucibles better than a cylindrical or vent-style chamber.
