Abstract
The present invention relates to an arrangement for treatment of articles by hot pressing. The pressing arrangement for treatment of articles by hot pressing comprises a pressure vessel including: a furnace chamber comprising a heat insulated casing and a furnace adapted to hold the articles. A heat exchanger unit is arranged below said furnace chamber and adapted to exchange thermal energy with pressure medium when the pressure medium is passing through said heat exchanger unit. According to the present invention, at least one first and second inlet or aperture, respectively, for passage of alternating warm and cold pressure medium are arranged in the heat insulated casing in proximity to the heat exchanger unit (i.e. at approximately same the height as, above or below the heat exchanger unit). The at least one second inlet (or lower inlet) is below the at least one first inlet (or upper inlet) but at same height as or below the heat exchanger unit.
