Trutherm manufactures 900 Degree Celsius (°C) Digital Box Furnace 885 x 875 x 875 MM Chamber for buyers who search by exact machine type, chamber size and 900°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 885 x 875 x 875 MM chamber with usable chamber volume of 677.6 litre, approximate power load of 40.4 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.
