FOAM & Deluge SYSTEMS
FOAM SYSTEMS
Foam has a wide range of foam products for all types of flammable liquids found in industries of today. We supply and service customers within Oil & Gas, Chemical, Pharmaceutical, heavy industries and other industries handling, transporting, processing or storing flammable liquids. The responsibility for protection of life, property and the environment demands the right equipment, systems, and the right foam. Selection of the correct foam must be based on the type of flammable liquids. Fires in water-immiscible fuels can be extinguished by use of high quality AFFF, FFFP or regular synthetic foam. Fires in Polar solvents require alcohol resistant foam. All these are available at Fire Protection Technologies and we work closely with our customers to select the correct foam.
FOAM EXTINGUISHING SYSTEM
Foam extinguishing system uses air–fighting foam, which is produced by aeration of foaming solution that is made of water and foam concentrate. The amount of air mixed specifies the type of foam: hard foam, medium or light foam. Foam extinguishing system is used for protection of flammable liquids, warehouses of dangerous materials, cable areas, aircraft hangars, refineries, in the chemical industry etc. Foam-cover prevents the access of oxygen, thus resulting in extinguishing fire and furthermore it prevents the flammable liquid from re-ignition.

Foam Fire Extinguishing System
Foam Fire Extinguishing System is divided broadly into two categories according to the chemical involved, namely Air Foam Fire Extinguishing System and Chemical Foam Fire Extinguishing system. Chemical Foam Fire Extinguishing System is considered obsolete and has generally been replaced by Air Foam Fire Extinguishing System. Being intended primarily for Flammable Liquids, Air Foam Fire Extinguishing System is installed at agencies, producers and storage site of explosives and combustibles. The system comprises Water Source, Fire Pump, Air Foam Concentrate, Proportioned, Foam Maker, Foam Discharge Outlet Control Panel, Pipe, Electric Wire, etc. A variety of Foam Discharge Outlet is provided to meet any shape of Hazard, conditions of location, etc. The system is divided into the following types.
Air Foam Chamber
- Air Foam Nozzle
- Air Foam Spray Hea
- Subsurface Foam Injection
- Air Foam-Water Monitor Nozzle
- High Expansion Foam Generators
Air Foam Concentrate is made into a fixed ratio of Air Foam Solution by mixing with water flowing through Feed Pipe and is mechanically stirred by Foam Maker which sucks air and generates great deal of Air Foam to extinguish a fire involving flammable liquids with smothering and cooling effect. Air Foam Concentrate makes fine foams with excellent stability and thermal resistance, and freely flows and develops on liquid surface such as petroleum to promptly extinguish a fire. It also sticks firm to a solid surface, level or vertical, to prevent the fire from spreading. Of the Fixed Air Foam Fire Extinguishing System, Air Foam Chamber and Subsurface Foam Injection are intended mainly for extinguishing a fire set on Exterior Storage Tanks, and Air Foam Spray Head for Flammable Liquid Hazards. Air Foam Nozzle is used as Supplemental Air Foam Hydrant for Exterior Storage Tanks or as Air Foam Hydrant for Flammable Liquid Hazard. Air Foam Monitor Nozzle is provided near the inlet port of Exterior Storage Tanks and particularly on a quay or a pier for extinguishing a fire set on oily outflow on the sea.
DELUGE SYSTEM : –
This system ensures rapid and complete flooding of the space with water, with high fire risk, such as aircraft hangers, power plants, generating stations and petrochemical facilities. On the basis of fire risk can be used for manual, pneumatic, hydraulic, or electric starting system .
DELUGE SYSTEM
DELUGE SYSTEMS
Adeluge fire sprinkler system is similar to a pre-action system except the sprinkler heads are open and the pipe is not pressurized with air. Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection system. The detection system is installed in the same area as the sprinklers. When the detection system is activated water discharges through all of the sprinkler heads in the system. Deluge systems are used in places that are considered high hazard areas such as power plants, aircraft hangars and chemical storage or processing facilities. Deluge systems are needed where high velocity suppression is necessary to prevent fire spread.
Applications for Deluge System
- Fuel Storage Tanks
- Oil Storage Tanks
- LPG Storage Facilities
- Hazardous Chemical Tanks
- Industrial Processing Vessels
- Flammable Liquid Storage Tanks
Dry Systems
Dry pipe systems are the second most common sprinkler system type. Dry pipe
systems are installed in spaces in which the ambient temperature may be cold
enough to freeze the water in a wet pipe system, rendering the system inoperable.
Dry pipe systems are most often used in unheated buildings, in parking garages, in
outside canopies attached to heated buildings (in which a wet pipe system would be
provided), or in refrigerated coolers.
Applications for Dry System
- Computer rooms
- Libraries
- Archives
- Aircraft hangers
- Valuable artifacts
- Refrigerated spaces
Dry Systems
Water-Mist Fire Protection Systems .
Arab Vision safety provide water-mist fire protection systems for different applications. Water is forced through micro nozzles at very high pressure to create a water mist with the most effective firefighting drop size distribution. The water-mist fire protection system can be used in place of deluge, gas, foam, dry chemical, traditional sprinkler and any other type of fixed fire protection system. It is efficient against most types of fires. This type of system controls suppresses and extinguishes fires by discharging a fine water mist at high velocity. The water mist is made by the system when it activates: it pushes the plain, potable water at high pressure through specially designed sprinkler and spray heads. Water is discharged at high velocity by high-pressure pumps or accumulators. It uses three mechanisms to fight fire: cooling, radiant heat blocking and local oxygen inerting
Water Mist System : –
The effectiveness of a water mist system in fire suppression depends on its spray characteristics, which include the droplet size distribution, flux density and spray dynamics, with respect to the fire scenario, such as the shielding of the fuel, fire size and ventilation conditions. The use of water mist fire suppression, when compared to the use of gaseous agents and traditional sprinkler systems, has revealed advantages such as immediate activation, High efficiency in the suppression of a wide variety of fires, Minimized water damage, environmentally sound characteristics, No toxic problem.
Applications for Water Mist System
- Diesel Generators
- Transportation
- Gas Turbines
- Power Plants
- Machine Spaces
- Highway Tunnels
- Museums
Water Mist System
The system is 100% environmentally- friendly. Traditional sprinkler systems use wetting as their main mechanism, and therefore use very large amounts ofwater. The water-mist technology uses water much more efficiently: it uses up to 90% less water than traditional sprinkler systems for the same application with equivalent or better performance. This system will help building owners and designers for green building practices and sustainability requirements. The system is also an optimal choice for special applications that are sensitive to water, i.e. museums, art galleries, data centers, engine rooms, etc.
