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.
