Abstract: A condensation oven arranged to treat a workpiece including a casing having an internal structure defining a hermetic enclosure accessible via at least one door, a heater device operable to heat the internal structure to a predetermined temperature to enable a fraction of vapor obtained by vaporizing a heat transfer liquid to condense onto the workpiece, a vapor circulation system configured to circulate the vaporized liquid within the hermetic enclosure such that a fraction of the vapor condenses onto the workpiece, an extractor device operable to extract vapor within the hermetic enclosure of the oven, and a control unit configured to control the heater device and the extractor device when the at least one door is closed.

Abstract: The invention relates to a method of applying heat treatment to a workpiece by means of at least one heat transfer liquid having a boiling point at a given value.

Abstract: The invention relates to a method for heat treating a workpiece by using at least one heat transfer liquid. The method includes the steps of placing a workpiece inside an oven that forms an internal cavity that is hermetically sealable, setting the oven at a temperature that is suitable for enabling a fraction of vapor of the heat transfer liquid to condense on the workpiece, introducing vaporized heat transfer liquid into the oven, allowing a fraction of the vapor to condense onto the workpiece, extracting the remaining vapor from the oven, and removing the workpiece from the oven.

Abstract: The invention relates to a machine for confining a primary fluid by means of a secondary fluid whose boiling temperature is lower than that of the primary fluid. The machine includes, in particular, primary vapor cooling means comprising a heat exchanger (11) for exchanging heat between the primary vapor and the secondary fluid (12), which means are provided with orifices (15) for exhausting the secondary vapor into the inside of the tank (4) so that the hat exchanger ensures that the primary vapor condenses and that the secondary fluid vaporizes, thereby making it possible to obtain thermal self-stabilization inside the tank.
