Functionally the same as a Glass Tempering Furnace, this unit is often called a kiln in the industry. It performs the heating phase of the tempering process at around 650°C. The working principle is a large, horizontal roller-hearth kiln that conveys glass sheets through heating and quenching zones. Its purpose is high-volume production of tempered safety glass for construction and automotive industries. The terminology "kiln" is a holdover from ceramic processing but is fully interchangeable with "furnace" in this context.
This configuration is suitable when the sample load must fit a 900 x 860 x 860 MM chamber with usable chamber volume of 665.6 litre, approximate power load of 40.1 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 general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.

Trutherm manufactures 800 Degree Celsius (°C) Glass Tempering Kiln 900 x 860 x 860 MM Chamber for buyers who search by exact machine type, chamber size and 800°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.
A muffle furnace isolates the sample from direct contact with heating elements or combustion gases, giving cleaner, more repeatable results than an open flame or hot-plate process.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
