Abstract
A pressing arrangement for treatment of articles by hot pressing includes a pressure vessel including a furnace chamber and a furnace to hold the articles. A fan circulates a pressure medium within the furnace chamber, and enhances an inner convection loop at a load compartment. The inner convection loop pressure medium has an upward flow through the load compartment, and a downward flow along a peripheral portion of the furnace chamber. A flow generator generates a flow of pressure medium into the load compartment downstream the fan to enhance the inner convection loop. The flow is generated by transporting the pressure medium upwards from a space below a bottom insulating portion and above a bottom end portion, and by injecting the pressure medium into the load compartment downstream the fan to enhance the inner convection loop.
