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 600 Degree Celsius (°C) Electric Box Furnace 200 x 200 x 400 MM Chamber for buyers who search by exact machine type, chamber size and 600°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 200 x 200 x 400 MM chamber with usable chamber volume of 16 litre, approximate power load of 8.8 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.
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.
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.
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.
