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.
Trutherm manufactures 700 Degree Celsius (°C) Glass Tempering Kiln 810 x 900 x 810 MM Chamber for buyers who search by exact machine type, chamber size and 700°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 810 x 900 x 810 MM chamber with usable chamber volume of 590.5 litre, approximate power load of 38.2 kW, rectangular - tall 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.

A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
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.
