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.

A pressing arrangement includes a pressure vessel comprising a furnace chamber. The furnace chamber comprises a load compartment arranged within the furnace chamber. The furnace chamber comprises at least one pressure medium guiding passage in fluid communication with the load compartment to form an inner convection loop, wherein pressure medium in the inner convection loop is guided through the load compartment and through the at least one pressure medium guiding passage and back to the load compartment, or vice versa. The pressure vessel comprises at least one adjustable throttle configured to selectively impede or obstruct pressure medium flow in at least a portion of the at least one pressure medium guiding passage, thereby selectively selectively impeding or obstructing a flow of pressure medium in the inner convection loop.

Pressing arrangement

A pressing arrangement () is disclosed. The pressing arrangement () comprises a pressure vessel () comprising a pressure cylinder (), a top end closure () and a bottom end closure (), a furnace chamber () for heating a pressure medium, a plurality of guiding passages (), a load compartment () configured for holding at least one article to be treated, and at least one flow generator () for circulating pressure medium within the pressure vessel. The pressing arrangement further comprises a heat exchanging element () arranged in the top end closure or in the bottom end closure. The heat exchanging element comprises at least one passage for allowing a flow of pressure medium through the heat exchanging element, and at least one circuit for allowing a circulation of cooling medium within the at least one circuit for a cooling of the pressure medium.

Pressing arrangement and method of cooling article in said arrangement

A pressing arrangement is disclosed, including a pressure vessel, a pressure medium supplying device configured to output a flow of pressure medium, and a pressure medium accumulator. In an embodiment, the pressure medium accumulator is positioned intermediate the pressure vessel and the pressure medium supplying device.

A pressing arrangement () is disclosed. The pressing arrangement () comprises a pressure vessel () and a furnace chamber () arranged within the pressure vessel (). The furnace chamber () is at least partly enclosed by a heat insulated casing () and arranged so that pressure medium can enter and exit the furnace chamber (). The pressing arrangement () comprises a plurality of pressure medium guiding passages () in fluid communication with the furnace chamber () and arranged to form an outer cooling loop within the pressure vessel (). The pressing arrangement () comprises a heat absorbing element () which is arranged within the pressure vessel () and which isconfigured to absorb heat from pressure medium having exited the furnace chamber ().
