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 775 x 400 x 400 MM chamber with usable chamber volume of 124 litre, approximate power load of 20.3 kW, rectangular - wide 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 800 Degree Celsius (°C) Digital Box Furnace 775 x 400 x 400 MM Chamber for buyers who search by exact machine type, chamber size and 800°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.
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.
