Abstract

Atmosphere and vacuum oven with a vacuum-tight container, which houses a loading chamber with heating elements and an antechamber with a heat exchanger, which allows the gaseous medium in the container to be cooled by means of a fan that circulates this medium, characterized by the fact that the fan (24) is arranged inside the loading chamber (16) on the wall (18) of the latter adjacent to the antechamber (15) and by the fact that Guide plates (26) are arranged around the load (22), which determine fixed circulation paths for the medium driven by the fan (24).
