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 1200 Degree Celsius (°C) Industrial Box Furnace 200 x 200 x 400 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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 200 x 200 x 400 MM chamber with usable chamber volume of 16 litre, approximate power load of 8.8 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.
Box furnaces take their name from the simple rectangular chamber, which makes them easy to load with trays, crucibles or irregularly shaped parts through a front-opening door.
Heat-treatment cycles such as annealing and tempering depend on a stable soak temperature, and the muffle-lined box chamber isolates the workpiece from direct flame or element contact for even heating.
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.
