HI-FOG Water Mist System

Marioff HI-FOG (High-Pressure Fog) ist das weltweit meistinstallierte Hochdruck-Wassernebel-Löschsystem auf Schiffen. Marioff (Vantaa, Finnland, seit 2007 Teil von Carrier/UTC) hat die Wassernebel-Technologie für den Marine-Bereich in den 1990er Jahren kommerzialisiert. HI-FOG ist Standard auf Kreuzfahrtschiffen (wo konventionelle Sprinkler nicht ausreichen) und zunehmend auch auf Frachtschiffen als Alternative zu Halon/CO2 im Maschinenraum.
