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 The water vapor and any air entering the tank are withdrawn to maintain the pressure constant during the cooling and the condensate from the withdrawn vapor is recycled to the spraying nozzles.
Refroidissement par vaporisation isobare de profilés thermoplastiques extrudés effectué à une pression égale à une colonne de 25 pouces de Hg dans un réservoir en pulvérisant de l'eau sur les produits extrudés. La vapeur d'eau et l'air entrant dans le réservoir sont retirés afin de garder la pression constante pendant le refroidissement, et le condensat provenant de la vapeur retirée est recyclé vers les buses de pulvérisation
