Characterized by its simple, box-shaped chamber, this furnace is a versatile workhorse for general heat treatment processes like annealing, tempering, and stress relieving. Operating from 600°C, it provides a uniform thermal environment. The working principle utilizes electric heating elements or gas burners lining the insulated walls of the rectangular chamber, with a door for front loading. Its purpose is to offer reliable and straightforward heating for a wide range of materials, including metals and ceramics, in batch processes. Common in tool rooms, forge shops, and labs, its simplicity and effectiveness make it widely popular.
Trutherm manufactures 600 Degree Celsius (°C) Box Furnace 200 x 200 x 300 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 300 MM chamber with usable chamber volume of 12 litre, approximate power load of 7.9 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.

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.
