An apparatus is located downstream of an extruder for cooling extruded material exiting the extruder. The apparatus includes a housing having a material passage. The material passage is dimensioned so as to have a larger cross section than a cross section of the extruded material. The apparatus further includes a system for controlling the temperature of at least a portion of the housing. The apparatus further includes a plurality of fluid passages in the housing and connectable to a source of pressurized fluid for providing fluid communication between the source of pressurized fluid and the material passage in the housing. The fluid passing through the fluid passages changes to a temperature having a value functionally related to the temperature of the temperature-controlled portion of the housing. The pressurized fluid passing through the fluid passages supports and cools the extruded material as the extruded material passes through the material passage.
