Gastight retort furnace with internal atmosphere circulation.
Electrically heated furnace suitable for annealing, tempering, reduction of internal stress, hardening or preheating of a metal charge in a closed gas-tight retort. Precisely defined protective atmosphere protecting the surface of the charge from unwanted changes with relatively low gas consumption. PKRC furnaces also have even better temperature distribution thanks to internal atmosphere circulation.
