UL Listed & Certified Aerosol Fire Suppression System


The KEY difference between our FAS-GreenSol Fire Suppression system and other aerosol fire suppression systems is that in our product, Fire extinguishing is accomplished by the interruption of the chemical chain reactions occurring in the flame and cooling and hence it acts in dual way and suppresses fire not only faster but also helps in reducing the chance of Reignition.

FAS - Condensed aerosol fire suppression is a UL Listed and Certified, Military grade, Emerson Group particle-gas based form of fire extinction system. The aerosol employs a fire extinguishing agent consisting of very fine solid particles and gaseous matter to extinguish fires. The condensed aerosol micro particles and effluent gases are generated by the exothermic reaction. They are cooled and "condensed" within the device and discharged as a combination of gaseous and solid particles.

Compared to gaseous suppressants, which emit only gas, and dry chemical suppression agents, which are powder-like particles of a large size (25 - 150 micrometres), condensed aerosols are defined by the National Fire Protection Association as releasing in a ratio of 60~70% gases and 40~30% finely-divided solids of less than 5 micrometres in diameter. The solid particulates have a considerably smaller mass median aerodynamic diameter (MMAD) than those of dry chemical suppression agents, remain airborne significantly longer, and leave hardly any residue within the protected area.

Whereas dry chemical systems must be directly aimed at the flame, condensed aerosols are flooding agents and therefore effective regardless of the location and height of the fire.

The condensed aerosol agent can be delivered by means of mechanical operation, electric operation, or combined electro-mechanical operation.

FAS - Green-Ex Aerosol Suppression systems use the latest technology that uses our patented solid compound that is the outcome of many years of research and development with various space organisations and military research centres. When activated the GreenSol solid compound is transformed into a rapidly expanding extremely effective and efficient fire extinguishing dry sprinkler condensed aerosol. Unlike gaseous agents, the total flooding effect is achieved without increasing the pressure in the protected area/volume.


Our Aerosol offers the following exceptional advantages

We offers a wide range of user-friendly self-contained fire extinguishing modules, as well as tailor made modular suppression systems to address the commercial, industrial and military market needs. Our smallest generator can protect even the smallest enclosures (≤ 0, 2 m3), while a single of our largest generator can protect a room up to 50 m3. Multiple generators can be used to protect large or odd shaped compartments.

Condensed aerosols' primary extinguishing mechanism involves the fourth element of the fire tetrahedron by means of chemical reactions with the free radicals of the flame, therefore interfering with the combustion process of the fire. Typically, condensed aerosol particulates consist of potassium carbonates that are produced from the thermal decomposition of a solid aerosol-forming compound that includes potassium nitrate as an oxidizer. As the aerosol particles surround and come into contact with the flame, the particulates absorb the flame heat energy, breaking down and releasing large concentrations of potassium radicals (K+) (ions with an unpaired electron). The potassium radicals bond with the hydroxide (OH+), hydrogen (H+) and oxygen (O+) free radicals which sustain flame's combustion process, producing harmless by-product molecules such as potassium hydroxide (KOH).

The potassium radicals are propagated since they are both consumed and produced by reaction with the fire radicals. Disrupting the reactions necessary to sustain the flame's combustion, the cycle continues until the combustion's chain reactions are terminated and the flame is extinguished.


The extinguishing performance of condensed aerosol fire suppressants is dependent on the density of aerosol particulates in the immediate vicinity of the flame. The extinguishing and design densities of aerosol fire suppression agents are generally expressed in kilograms per cubic meter (gm/m3). Thus, the efficiency of aerosol extinguishing agents varies depending on a number of factors, such as the chemical composition of the Aerosol, location of the aerosol relative to the flame, the proximity of other combustible flammable materials, the type of fuel involved, etc.

The KEY difference between our FAS-GreenSol Fire Suppression system and other aerosol fire suppression systems is that in our product, the design density is 75gm/m3 as compared to all others having more than 90 gm/m3. Which means the overall mass required for protecting the enclosed space shall be less hence resulting in cost effective solution.


The United States Environmental Protection Agency has approved condensed aerosol fire suppression systems as acceptable substitutes for Halon 1301 in Total Flooding Systems. Aerosol extinguishers are also non-ozone depleting and carry little or no global warming potential.


Condensed aerosol systems are suitable for special hazards applications as replacements for Halon 1301 systems and high-pressure carbon dioxide systems. Aerosol systems can also be used as alternatives to clean agent gaseous suppressants or water-mist systems.

There are two ways for using condensed aerosol based fire suppression systems:

1) As a total flooding fire protection system
2) As a local application fire suppression system ( Handy tool).

FAS - GreenEx ( EMERSON GROUP PRODUCT ) Fire Suppression systems are highly effective, innovative and environmentally friendly fire suppression and extinguishing systems for almost all thinkable applications like server rooms, generator rooms, control rooms, sub stations, no break rooms, archives and inside construction vehicles, electric buses and wind turbines, document & record rooms and vehicles.
