Unitor High Expansion Foam Fire Extinguishing System

A cost effective and safe alternative to CO2
Unitor High Expansion Foam Fire Extinguishing System (Unitor HiFoam System) uses high expansion foam consisting of a synthetic foam concentrate water and air, which is highly effective for machinery space applications.


The system is designed as total flooding system for machinery spaces of Category A, cargo pump rooms and other spaces onboard vessels or on offshore instllations needing fire protection.


The system can be installed as total flooding for the entire main machinery room or for individual compartments within that space, pump rooms and other separate machinery spaces. Zoning provides an option for selective and sequential release, which gives optimised protection of your equipment and reduce water capacity needs.


The expansion ration of 1:666 using internal air eliminates the need for extensive air ducting and fans, unlike traditional systems which utilise external air to create the air/foam mix.


Unitor HiFoam System is a cost effective solution that is environmentally friendlier, non-toxic and harmless to people.
