In a chamber (24) in a pressure vessel, e.g. an autoclave (10), articles (26) are heat-treated by water, which is sprayed over the articles through nozzles (20) and supplies heat to or removes heat from the articles. Simultaneously, a gaseous medium, e.g. a mixture of steam and air, is forced by an impeller (34) to flow through the articles in countercurrent to the water. By this a very even temperature distribution of the articles in the chamber (24) is obtained.
