This kiln features a box-shaped design, providing a straightforward and efficient chamber for firing ceramics, glass, or enamel. Operating temperatures can reach 900°C or higher, suitable for bisque and glaze firings. The working principle is similar to a box furnace, with heating elements surrounding an insulated brick chamber and a heavy door for heat retention. Its purpose is to offer consistent, controllable firing for potters and artists, accommodating shelves of ware. It is a standard design in educational studios, small-scale production potteries, and for firing technical ceramics due to its even heat distribution.

Trutherm manufactures 1100 Degree Celsius (°C) Box Kiln 875 x 465 x 465 MM Chamber for buyers who search by exact machine type, chamber size and 1100°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 875 x 465 x 465 MM chamber with usable chamber volume of 189.2 litre, approximate power load of 24.1 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.
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.
