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 820 x 820 x 875 MM chamber with usable chamber volume of 588.4 litre, approximate power load of 38.2 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 1300 Degree Celsius (°C) Digital Box Furnace 820 x 820 x 875 MM Chamber for buyers who search by exact machine type, chamber size and 1300°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.
Box furnaces take their name from the simple rectangular chamber, which makes them easy to load with trays, crucibles or irregularly shaped parts through a front-opening door.
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.
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.
