Abstract

L'invention concerne une unité de lavage et de nettoyage (1) pour enlever les huiles, graisses et autres salissures de machines et de composants d'automobiles. Les composants sont traités à la vapeur dans l'unité et les salissures enlevées sont dirigées à travers un tamis (3) disposé au sol vers un bac de sédimentation (13) dans lequel ils se déposent. L'eau, les huiles et les graisses passent à travers un tampon absorbant (7) qui retient les huiles et les graisses. L'eau est ensuite filtrée pour être utilisée à nouveau dans l'unité de nettoyage utilisant la vapeur.
