Fire fighting systems

FOAM

Low expansion foam:

Foams with an expansion ratio * 1 to 20. Application areas: Outdoor storage tank, interior flammable hazardous area containing flammable liquids, transfer and loading platforms for chemical and petroleum facilities, ditch zone around the tank area, unconfined transportation areas.


Medium expansion foam:

Foams with an expansion ratio of 20 to 200. Application areas: Ordinary inflammables, flammable/combustible liquids and its combinations with ordinary combustible materials

High expansion foam:

Foams with an expansion ratio of 200 to about 1000. Application areas: Ordinary inflammables, flammable/combustible liquids and its combinations with ordinary combustible materials, liquefied natural gas

* Indicates the ratio of the final foam to the volume of the original foam solution of the product.

Fire fighting systems

GAS

These are ideal systems for enclosed volumes especially for electric fires. Based on oxygen suppression, volume tightness is important in such systems. Systems generally consist of detection systems, extinguishing panel, extinguishing agent storage and piping.


Carbondioxyde (CO2) extinguishing systems:

Due to the nature of carbon dioxide, besides suppressing oxygen these systems reduce the ambient tempurate quickly and prevent the ignition.

Clean gas extinguishing systems:

These are systems that are applied with gases which are harmless to the atmosphere and mixed at special rates, stored at high pressure and contain proper fittings accordingly.

Inert gas extinguishing systems:

These are systems that are applied with inert gases (such as argon) which are harmless to the atmosphere, stored at high pressure and contain proper fittings accordingly

Low pressure carbondioxyde (CO2) extinguishing system (LPCO2):

In this system, the extinguishing system agent is stored in a single tank at a pressure of approximately 20-22 bar and a temperature of -17 degrees. This method is much more economic than the equivalents for large volumes extinction and protection. Maintenance and refilling is so easy because of it can be filled on site.

High pressure CO2 extinguishing system:

In this system CO2 is stored within high pressure tube sets. It is effective for smaller volumes.

Application areas:

Transformers, oil and fuel storage tank, chemical facilities and chemical storage tanks, armouries, aircraft and helicopter hangars, pumping stations, hydroelectric facilities, generators, shipyards, yacht and boat harbours (marinas), fueling and unloading facilities, refineries

Fire fighting systems

WATER

Sprinkler systems:

It is the most preferred extinguishing system except for B, D and E class fires. It is one of the extinguishing systems that react fastest. It can be applied in wet or dry type depending on the hazard features.

Wet pipe sprinkler system:

The water pressurized by the fire pumps remains inside the pipe network completely filled. The closed sprinkler group bursts which is triggered during a fire, allowing water to flow.

Dry pipe sprinkler system:

The water pressurized by the fire pumps remains in the piping until a deluge valve; there is pressurized nitrogen gas between the valve and the sprinkler system. It is responded to a fire, as first all of nitrogen in piping then the water flows from the closed type sprinklers that are triggered in during a fire.

Water mist systems:

These systems used to extinguish fire by suppressing oxygen in the air by creating mist screen on the protected area or object, which have much lower water consumption than standard sprinkler systems

Hydrant system:

These systems are used in water fire-fighting systems to supply water from different regions on the site.
