This is an electrically heated version of the standard box furnace. Operating at temperatures like 600°C, it uses electric resistance elements (often nickel-chromium alloy) lining the insulated box chamber. The working principle provides clean, quiet, and easily controllable heat without combustion gases, making it ideal for laboratories and shops where fumes are a concern. Its purpose is for general heat treatment—annealing, tempering, preheating—of metals and other materials. Its simplicity, reliability, and ease of installation (requiring only power) make it extremely popular.
Trutherm manufactures 1400 Degree Celsius (1400°C) Electric Box Furnace 480 x 875 x 480 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.
This configuration is suitable when the sample load must fit a 480 x 875 x 480 MM chamber with usable chamber volume of 201.6 litre, approximate power load of 24.7 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.

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.
Tool rooms and forge shops favour box furnaces because a single chamber can handle annealing, hardening and tempering cycles without changing fixtures between jobs.
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.
