Pressing arrangement () comprising a pressure vessel () and a furnace chamber () arranged therein defining a treatment region for an article (), the treatment cycle including a cooling phase. The pressing arrangement () comprises a fan () configured to circulate a pressurised gas within the pressure vessel () and a heating device () for heating the pressurised gas in the treatment region. It further comprises a control and processing module () configured to, during the cooling phase: obtain temperature values in the treatment region; based on these values, determine a cooling power for cooling of the pressurised gas in the treatment region; determine a difference between a cooling power required to obtain a selected value of cooling rate of the pressurised gas and the determined cooling power; and based on this difference, control the fan's () rotational speed so as to make the difference decrease. If the cooling power provided by the operation of the fan () exceeds a cooling power corresponding to the desired cooling rate of the pressurised gas, the control module () is configured to, based on the determined difference, heat the pressurised gas using the heating device () to make the difference decrease.

Method in a pressing arrangement

A method in a pressing arrangement is disclosed. The pressing arrangement comprises a pressure vessel arranged to hold pressure medium therein during use of the pressing arrangement, the pressure vessel including a treatment region therein, wherein the treatment region is arranged to accommodate at least one article. The pressing arrangement comprises at least one controllable pressure medium supplying device configured to transport pressure medium during a cooling phase from another region in the pressing arrangement to the treatment region, wherein the temperature of the pressure medium in the other region is lower than the temperature of the pressure medium in the treatment region during at least part of the cooling phase. The method includes adjusting at least one operational parameter of the at least one controllable pressure medium supplying device, to adjust the pressure medium supplying rate thereof.

A method in a pressing arrangement is disclosed. The pressing arrangement comprises a pressure vessel arranged to hold pressure medium therein during use of the pressing arrangement, the pressure vessel including a treatment region therein, wherein the treatment region is arranged to accommodate at least one article. The pressing arrangement is arranged so that pressure medium can enter and exit the treatment region. The pressing arrangement comprises at least one controllable pressure medium supplying device configured to transport pressure medium during a cooling phase from another region in the pressing arrangement to the treatment region, wherein the temperature of the pressure medium in the other region is lower than the temperature of the pressure medium in the treatment region during at least part of the cooling phase. At least one value indicative of at least one temperature in the pressure vessel is obtained. Based on the at least one value indicative of at least one temperature in the pressure vessel, at least one operational parameter of the at least one controllable pressure medium supplying device is adjusted, whereby the pressure medium supplying rate of the at least one pressure medium supplying device is adjusted. A pressing arrangement in which the method may be carried out is also disclosed.
