Abstract
The present invention relates to an arrangement for treatment of articles by hot pressing and preferably by hot isostatic pressing. In particular, the present invention relates to such an arrangement capable of obtaining a rapid rate without the need of special purpose valves for the cooling. A furnace chamber is provided inside the pressure vessel of the arrangement and a heat insulated casing arranged to surround the furnace chamber. A bottom insulating portion is arranged beneath the furnace chamber. Further, a fan having a controllable number of revolutions for circulating the pressure medium within the furnace chamber is arranged in the pressure vessel, and preferable within the furnace chamber. At least one feeding passage is arranged to allow feeding of pressure medium from a region being colder than a region within the furnace chamber towards an inlet of the fan, wherein an amount of pressure medium being fed to the inlet of the fan can be controlled by adjusting operational parameters of the fan.
