Trutherm manufactures 1200 Degree Celsius (°C) Digital Box Furnace 450 x 600 x 450 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 450 x 600 x 450 MM chamber with usable chamber volume of 121.5 litre, approximate power load of 20.1 kW, rectangular - tall 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.
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.
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.
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.
