Strengthening Extinguishing Water

Foam Fire Extinguishing System Groups

There are basically three different application methods of foam extinguishing systems. Which method to choose depends on the type of hazard, application period, regulations, and technical characteristics of the substance or equipment to be protected.

Foam extinguishing systems are preferred when water extinguishing alone is not sufficient.

  • Low Expansion Foam Extinguishing Systems

  • Medium Expansion Foam Extinguishing Systems

  • High Expansion Foam Extinguishing Systems

Detection – Activation – Application

Fully Automatic Foam Extinguishing System Types

While medium-expansion applications are used by firefighting teams, low and high-expansion applications are carried out by human-independent systems.

Low Expansion
Foam Based Fire Extinguishing Systems

In low-expansion systems, the unit extinguishing fluid is volumized with air at a ratio of 1:20 and applied to the surfaces. Thanks to the foam concentrate added to the water, the surface tension of the solution is reduced and this solution spreads over the burning liquid and provides a blanket-like cover. In this way, a barrier is established between fuel and oxygen.

Scope of application:

  • Refineries, Production Areas and Chemical Warehouses
  • Airports and Fuel Filling Areas
  • Fixed and Floating Roofed Tanks and Tank Pools

High Expansion
Foam Based Fire Extinguishing Systems

The volume of the foam and water solution in the range of 1:200-1000 is defined as high expansion. This application is preferred in situations where the fire risk spreads very quickly, the fire load is very high and the protected equipment is very valuable. These systems protect the commodity in three dimensions.

Scope of application:

  • LNG Tanks, Warehouses, Production Areas
  • Helicopter and Aircraft Hangars / Runways
  • Cable Tunnels, Underground Storages, Recycling Facilities

Basic System Components

Foam Concentrate

Synthetic and protein based dense foam essence

Storage Tanks & Pumps

Atmospheric or membrane aboveground tanks

Proportioners & Mixers

Ensures water and foam are prepared in the correct ratio

Discharge Units

Nozzle, foam maker-chamber, and generators

Extinguishing Liquids

Foam Concentrates

Concentrated chemicals are used to cover burning surfaces, push oxygen and cool the fuel.

Fluorinated Synthetic Water Film Forming Foams

It is an aqueous film-forming foam concentrate consisting of a mixture of fluorocarbon, hydrocarbon surfactants and various solvents and stabilizers. Only C6 Pure fluorosurfactants are used in AFFF formulations. AFFF 3% uses the unique film forming effect to cut off the oxygen supply to the fire.

Alcohol Resistant Fluorinated Synthetic Water Film Forming Foams

It is an alcohol-resistant aqueous film-forming foam concentrate consisting of a mixture of fluorocarbon, hydrocarbon surfactants and polymers, various solvents and stabilizers. All AFFF-ARC foam concentrates are formulated with 100% C6 Pure fluoro-surfactants and fluoro-polymers.

High Expansion foam Concentrate

Viking 3% XMAX is a new generation high performance and multi-purpose foam concentrate. HIt can be used on hydrocarbon and solvent fires. This special foam, which does not contain fluorine, can be preferred in medium and low expansion applications. It is suitable for use with sea water and fresh water. With its 3% mixture ratio, it is extremely effective in extinguishing large-scale fires.

Foam Concentrates without synthetic fluoride

Due to environmental concerns and new legislation around the world, fluorine-free foam concentrates have become widespread. These new foam concentrates, which have PFAS1-free foams and can perform at the levels of traditional fluorinated (AFFF2) systems, can be used safely on both hydrocarbon and solvent fires.

Storage Units

Foam Tanks & Pumps

The dense foam concentrate is kept in a pressurized or atmospheric tank. In systems with a foam pump, dosing is provided at the correct rate with the pressure of the water.

Atmospheric Foam Tanks

These products, made of stainless steel with capacities of 200-600 Liters, are generally used at points where small spaces or a certain device or equipment needs to be protected. These tanks contain venturi type or proportional foam-water mixers.

Bladder Foam Tanks

These tanks are made of carbon steel. There are two types of options: horizontal or vertical. In these products, which offer foam storage options in the range of 100-15000lt, the membrane in the tank is sent to the mixer unit with water pressure.

Foam Pumps

Foam pumps, which are used to send the foam-water mixture over long distances, facilitate the design processes. A positive displacement electric pump is used to deliver the water and foam mixture to the desired point.

Dosing & Mixing

Foam Proportioners

The concentrate is mixed in line with pressurized water at a predetermined rate, flow rate, and pressure.

Wide Range Proportioner

Wide-range proportions are connected to atmospheric or membrane foam tanks via an external, corrosion-resistant deluge valve. These proportioners are produced in the factory with fixed ratios of 1%, 3% and 6%. Since the friction loss is low during the passage of water and foam concentrate, it can operate at low pump pressure.

Venturi Type / Proportional Proportioners

This equipment ensures that a certain amount of foam concentrate is mixed into the water passing through it. Since the amount of foam to be mixed is proportional to the pressure and flow rate at that point, the calculation must be made very carefully. The pressure loss in these products is high due to the internal structure of the material.

Foaming Outlets

Discharge Units

The foam and water solution mixed in the proportioner is expanded with air at the injection point.

Sprinkler & Nozzles

Expansion and classic sprinkler heads are used with air inlet, and brass and stainless heads are used in low-hazard areas.

Foam Makers & Chambers

These products, made of carbon steel, are generally used in low expansion foam application in tanks and overflow pools.

Foam Monitors

These products, which are electric motorized, oscillating or manually controlled, are used in medium and high hazard liquid fires from long distances.

Foam Generators

High-expansion foam generators, offered with or without fans, are generally used in aircraft hangars or chemical warehouses.

About System Approvals

All equipment that makes up the foam extinguishing system has a single system approval.

Activation of Foam Extinguishing Systems

Fire Detection System

Fire Detection Panel

Triggering of foam extinguishing systems occurs via a conventional panel.

Detectors

Two different independent detection lines are used  using smoke, heat, or flame detectors.

Warning and Alarm Devices

Sirens and flashers are used inside and outside to evacuate the volume before extinguishing.

Supervisory Connections

The central detection system remotely monitors error and alarm information on the extinguishing panel.

Strengthening Extinguishing Water

CAF – Pressurized
Air Foam System

The amount of water used in this new technology, where a mixture in a different form is obtained by adding compressed air to the classical foam extinguishing mixing unit, has been significantly reduced. The most prominent feature of this system is that it eliminates the need for large water tanks and fire pumps. Drainage of the foam-water mixture is no longer a problem. This makes it easier to reactivate the protected equipment and site.

  • The system is FM approved. It is suitable for local application in liquid fires.

  • It uses less foam concentrate than classical systems.

  • It can be activated electrically, pneumatically and manually.
