Trutherm Digital Box Furnace models combine box chamber construction with digital control for ashing, heat treatment, testing and high-temperature processing.
This configuration is suitable when the sample load must fit a 460 x 460 x 900 MM chamber with usable chamber volume of 190 litre, approximate power load of 24.1 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.

Trutherm manufactures 1400 Degree Celsius (1400°C) Digital Box Furnace 460 x 460 x 900 MM Chamber for buyers who search by exact machine type, chamber size and 1400°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.
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.
