This furnace incorporates a sealed retort—a vessel or chamber within the furnace—that holds the workload. Operating from 600°C, the retort can be filled with a controlled atmosphere (like endothermic gas for carburizing) independent of the combustion chamber. The working principle allows for processing in reactive atmospheres while the heating is done externally, protecting the furnace's heating elements from the atmosphere. Its purpose is for processes like carburizing, nitriding, sintering, and bright annealing where atmosphere composition is critical and must be contained.
Trutherm manufactures 800 Degree Celsius (°C) Retort Furnace 725 x 375 x 375 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.
This configuration is suitable when the sample load must fit a 725 x 375 x 375 MM chamber with usable chamber volume of 102 litre, approximate power load of 18.7 kW, rectangular - wide chamber profile.

Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
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.
