Foam / Water / Dry Chemical Fire Suppression Systems

Fire suppression systems are used to extinguish or prevent the spread of fire. Suppression systems use a combination of dry chemicals and/or wet agents to suppress equipment fires. Deluge, foam supply shall be provided for all areas where hydrocarbon or alcohol pool fires are likely to occur.
The fire water system shall be operable at all times, including periods of maintenance according to international standards and shall ensure adequate supply of water for fire fighting.

  • DIFF System
  • Deluge System
  • Dual agent System
  • Dry Chemical System
  • Foam Monitor System
  • Foam System (Local, Centralized, Hi-Expansion)
  • Foam Hose Reel Unit
  • Sprinkler System
  • Water Mist System
  • Hydrants

In addictional to

  • Heli-Refueling System
  • Chemical Injection Nozzle
  • Hydro power pack
  • E-house (HVAC, E&I, Fire fighting system)

Gaseous Fire Suppresssion System

Gaseous fire suppression, also called clean agent fire suppression, is a term to describe the use of inert gases and chemical agents to extinguish a fire.

There are three common clean agent fire suppression systems to choose from, including FM-200, Novec™ 1230, and Inergen Clean Agent System.
All systems use gases that are safe for the environment and humans,
but they utilize different ways of suppressing a fire.

The FM-200 system is stored as a liquid and vaporizes when discharged.
The system displaces the oxygen around a fire, but heat absorption is its primary extinguishing capability.

The Inergen system uses inert gases- nitrogen, argon, and carbon dioxide-
to reduce the oxygen level and suppress the fire. While carbon dioxide is included, the concentration is safe for humans and the environment.
Once the Inergen concentration is discharged, it returns to the atmosphere in its natural state.

The Novec™ 1230 system uses a liquid that is vaporized when discharged, similar to the FM-200 system.
However, unlike the FM-200 which suppresses the fire by heat absorption or cooling, the Novec™ 1230 displaces the oxygen around a fire to suppress it.
