The Unitor High Expansion Foam fire extinguishing system (Unitor High Foam system) uses 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 enclosed spaces onboard vessels and offshore instllations.



Key features

  • Fast and effective solution for machinery space fires with filling rate of 1.63 metre per minute
  • The system can be installed as a total flooding solution for the entire machinery room or for individual compartments
  • Quick activation of the system minimises fire and heat damage to equipment and structures
  • The foam is not harmful and the cooling effect hiders the fire from reigniting after it is extinguished
  • No hazardous decomposition products that could cause damage are formed
  • Zoning provides an option for selective and sequential release, which gives optimised protection of your equipment and reduce water capacity needs

Solution benefits

  • Compliant solution
  • Easy to install
  • Space saving installation
  • Easy to operate
  • Requires minimal maintenance
  • For services purposes, replacement of the foam concentrate is available worldwide

A cost effective solution

Designed for optimal system performance, keeping both installation and operational costs low

  • Do not require an external foam generating room
  • The high expansion ratio and the stable condition of the foam results in a very rapid filling rate with low consumption of water and foam concentration
  • The expansion ratio of 1:666 using internal air eliminates the need for extensive air ducting and fans
