\n\t\t\t\t\t\tCes \u00e9changeurs sont largement utilis\u00e9s pour refroidir les moteurs principaux et auxiliaires avec de l'eau douce ou de l'eau de mer. Ils sont \u00e9galement essentiels dans les syst\u00e8mes de conditionnement des carburants pour chauffer et stabiliser les carburants lourds. Dans les unit\u00e9s de dessalement, ils servent de condenseurs ou d'\u00e9vaporateurs, et dans les processus de traitement des gaz tels que les \u00e9purateurs ou l'EGR, ils contribuent \u00e0 la r\u00e9cup\u00e9ration de la chaleur et \u00e0 la r\u00e9gulation de la temp\u00e9rature. Leur format compact permet de les int\u00e9grer facilement dans l'espace limit\u00e9 des installations maritimes. \t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\tEn fonction de l'exposition \u00e0 l'eau de mer et de l'agressivit\u00e9 des fluides, les \u00e9changeurs Nexson et Thermowave sont propos\u00e9s dans des mat\u00e9riaux de qualit\u00e9 marine tels que l'acier inoxydable 316L, Duplex, Super Duplex ou le titane. La conception soud\u00e9e des \u00e9changeurs Plate & Shell assure une \u00e9tanch\u00e9it\u00e9 durable et une maintenance minimale. Les plaques \u00e0 joints de Thermowave, quant \u00e0 elles, facilitent la maintenance et l'adaptabilit\u00e9 lorsqu'un entretien modulaire est n\u00e9cessaire. Les deux options assurent un fonctionnement efficace et fiable dans des conditions marines exigeantes. \t\t\t\t\t<\/p>\n\t\t\t\t\n\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t
