The present invention relates to an arrangement for treatment of articles by hot pressing and in particular by hot isostatic pressing. The pressing arrangement includes a pressure vessel and a furnace chamber adapted to hold articles, which furnace chamber is provided inside the pressure vessel. At least one guiding passage communicating with the furnace chamber forms an outer cooling loop, wherein the pressure medium in a part of the outer cooling loop is guided in proximity to pressure vessel walls and the top end closure before it re-enters into the furnace chamber. Further, a guiding channel element is located in the at least one guiding passage forming the outer cooling loop is arranged with at least one pressure medium channel for guiding the pressure medium from a central opening of the heat insulated casing radially and circumferentially towards a lateral wall of the pressure cylinder. The at least one pressure medium channel has a substantially constant cross-sectional area in a flow direction of the pressure medium.
