A METHOD IN A PRESSING ARRANGEMENT

Pressing arrangement (100) comprising a pressure vessel (1, 16, 17) and a furnace chamber (18) arranged therein defining a treatment region for an article (5), the treatment cycle including a cooling phase. The pressing arrangement (100) comprises a fan (35) configured to circulate a pressurised gas within the pressure vessel (1, 16, 17) and a heating device (36) for heating the pressurised gas in the treatment region. It further comprises a control and processing module (6) 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 (35) rotational speed so as to make the difference decrease. If the cooling power provided by the operation of the fan (35) exceeds a cooling power corresponding to the desired cooling rate of the pressurised gas, the control module (6) is configured to, based on the determined difference, heat the pressurised gas using the heating device (36) to make the difference decrease.
