This furnace is used for annealing processes, which soften metals and relieve internal stresses induced by machining, welding, or cold working. Operating at temperatures like 550°C, it heats materials slowly and uniformly to a point below their melting point. The working principle relies on a thermally insulated chamber that allows for precise control over both the ramp-up to the target temperature and the subsequent controlled cooling rate. Its primary purpose is to restore ductility, improve electrical conductivity, and enhance dimensional stability of metals like copper, steel, and brass. It is a standard piece of equipment in metal fabrication shops and wire manufacturing facilities.

Trutherm manufactures 1000 Degree Celsius (°C) Anneal Furnace 660 x 660 x 875 MM Chamber for buyers who search by exact machine type, chamber size and 1000°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 660 x 660 x 875 MM chamber with usable chamber volume of 381.2 litre, approximate power load of 32 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 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.
