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 640 x 870 x 640 MM chamber with usable chamber volume of 356.4 litre, approximate power load of 31.1 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.

Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
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.
