This is an industrial-scale box furnace engineered for high-temperature applications, capable of reaching 1200°C or more. It combines the simple, batch-oriented chamber design of a box furnace with the robust heating and insulation needed for extreme heat. The working principle involves heavy-duty heating elements and refractory brick to handle large, heavy loads. Its purpose is for sintering large ceramic parts, heat-treating large batches of alloy components, or calcining materials in industries like aerospace, automotive, and ceramics manufacturing.

Trutherm manufactures 1200 Degree Celsius (°C) High-Temperature Industrial Box Furnace 430 x 430 x 795 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 430 x 430 x 795 MM chamber with usable chamber volume of 147 litre, approximate power load of 21.7 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.
Tool rooms and forge shops favour box furnaces because a single chamber can handle annealing, hardening and tempering cycles without changing fixtures between jobs.
Where sample orientation is not critical, the flat shelf and square chamber of a box furnace generally load faster than a cylindrical tube furnace of similar volume.
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.
