ABSTRACT:
An isobaric vaporization cooling for extruded thermoplastic profiles is carried out at 25 inches Hg in a tank by spraying water onto the extrusions. The water vapor and any air entering the tank are withdrawn to maintain the pressure constant during the cooling and the condensate from the withdrawn vapor is recycled to the spraying nozzles.
