A heat treatment apparatus for vacuum and high pressure operation includes a container within a vessel separated by thermal insulation. The vessel has a door for access to the container. Both the container and thermal insulation have separate doors mounted on a common frame pivotally mounted inwardly of the vessel door. The container door can be opened and closed from otuside the vessel when the thermal insulation and vessel doors are closed. Normally the container door is kept open in case of failure of the closing mechanism or in the event of a power failure.
