Expansion Foam System

  
Fire on ships carrying flammable liquid cargoes is an extreme danger due to ies explosive liquid storage.

NK Expansion Foam Firefighting System is the best Expansion Foam Firefighting System with Higher expansion ratio, Quick operation, Less installation space, Less residue after fire extinguishing, Easy maintenance with major class societies		   Expansion Foam System

Tecnical Detail of System
Tecnical Detail of System
 
NK Expansion Foam Firefighting System is installed mainly in ship deck area for low expansion foam system but it can also cover enclosed area using high expansion foam system.
 

Extinguishing process of NK Expansion Foam System
A foam system consists of water supply, foam liquid storage, a proportioning device and a distribution. The foam liquid is stored in a tank, the material of which can be mild steel with painting, stainless steel or GRP. The Tank must be completed with vent, gauge and access manhole. The foam is delivered by a centrifugal foam pump to a foam proportioner that mixes 1 - 6% of foam liquid and 97-94% sea water. Foam Solution is supplied to the deck monitors, foam nozzle or foam generator.
 
System Application
  1. ships carrying flammable liquid cargoes
  2. tanks which rupture either by explosion or collision
  3. On deck for flammable liquid cargoes

Extinguishing process of NK WATER MIST System

NK's water mist system is based on the principle that small water evaporates early over the course of the fire and in that way the heat in the areas is absorbed. The size of droplets is classified as NFPA 750 class1.

This extremely small droplet size makes the water mist system highly effective and uses only small amount of water, which means water damage is limited. The key factors are the system ability to cool and the localized oxygen displacement effect.

N2 Firefighting System

  
The N2 system has been designed to human safety and developed as the most economical alternative fire extinguishant to Halon and CO2 enabled to protect all hazards environmentally friendly methods.
