Trutherm Lab Box Furnace models are designed for laboratory users needing a box chamber, digital controls, temperature choices and chamber dimension options.
Trutherm manufactures 1200 Degree Celsius (1200°C) Lab Box Furnace 240 x 240 x 450 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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 240 x 240 x 450 MM chamber with usable chamber volume of 25.9 litre, approximate power load of 10.7 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.
Equivalent chamber references: 240 x 240 x 450 MM, 24 x 24 x 45 CM and 9 x 9 x 18 INCH.

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.
