Overview on Aerosol Fire Suppression Systems

February 23, 2023

Our aerosol fire suppression systems can be divided into 5 types: Mini Aerosol Series, Floor Standing Series, Wall-mounted Series, Portable Series and Lithium battery series.

For Mini Aerosol


Mini series of aerosol have a special name of “MINISOL”, which have 5 styles of activation mode (actuator mode), there are: electrical (electric or electronic) start, thermal cord start, thermo bulb (glass bulb) start, electrical plus thermal cord start, electrical plus thermo bulb start.

  • Firstly, Electrical activation mode, this one use an electrical cable as actuator to start the minisol aerosol fire  extinguishing device. the power supply from power source could be 3 to 24 VDC or 3 to 380 VAC, it can work standalone by matching with a standalone temperature detection element called “Thermal Activation Generator TAG”(Also called Thermal Activation Device TAD).
  • Secondly, Thermal cord activation mode, this one use a  rated temperature of 175℃ or 300℃ thermal cord as actuator to start the minisol aerosol fire suppression system, it is automatic to detect and suppress fire; the thermal cord starts the fire extinguisher by means of self-combustion.
  • Thirdly, Thermo bulb activation mode, this one use a rated temperature of 57℃,68℃,79℃ or 93℃ thermo glass bulb as actuator to trigger the minisol aerosol generator, it is also automatic to detect fire and extinguish fire; The core component of this style aerosol system is glass bulb, which is a temperature sensing element, and the best brand is “JOB BULB” from Germany.
  • Fourthly, Electrical plus thermal cord activation mode, this is combined electrical activation and thermal cord activation function together on the device, both thermal cord to start and electrical power supply to start.
    Fifthly, Electrical plus thermo bulb activation mode, this one not only be triggered by electronics power, but also by temperature sensing of glass bulbs; It is generally used in relatively static space.

Mini aerosol fire extinguisher is mostly use in electrical panel, vehicles and wind turbine, so people also will like to name it “electrical panel fire protection system“,”vehicle fire suppression system” and “wind turbine fire extinguishing system“.

Its cylinder material is made of 304 stainless steel, so it can be installed in a humid environment.

For Floor Standing Aerosol

Floor standing Series of aerosol is a larger size of fire suppression tool, which is placed on the floor, it is in cuboid shape, and painted in silver-white or red color.

The electrical activation power supply are 3 to 24 VDC or 3 to 380 VAC; It is generally used for extinguishing fire in large space, but better not to exceed 1600 m³, the protection space could be telecommunication room, data processing room, server room, computer room, switch-gear room, power distribution and generator room etc.

For Wall-Mounted Aerosol

Wall-mounted series of aerosol is an style which is in cylindrical shape and in red colour, its main power supply is also 3-24 VDC or 3-380; just that of floor standing aerosol, it is mainly used in larger spaces.

Its advantage is that it does not occupy space, because it is hung on the ceiling or installed on the wall.

For Lithium Battery Pack Aerosol 

Lithium battery pack is a special hazard where is hard to make a fire protection in such as narrow and limited space, so for lithium battery fire protection, we specially developed a new style aerosol-a micro size of aerosol with capacity ranging from 8 grams to 60 grams.

It is special made for lithium battery energy storage system, it has a fashionable appearance, is also very small, and is easy to install; furthermore, it also can be applied in electric motors, electric bike and small size of electrical cabinet.

For Manual Operation Aerosol 

Manual operation aerosol also named manual throwing aerosol extinguisher, it is generally used by special departments, such as: firefighters, police and the army, so we normally not have stock in our workshop, if interest, this product needs to be customized to produce.

For Portable Aerosol

Portable series of aerosol is a new  invention, it is portable,compact and small, it is developed to extinguish small fires in some specific places like offices, kitchen, outdoor camping tent, government office, family car, hotels, storage facilities etc.

Above aerosol fire suppression system are made up of main chemicals of strontium nitrate and potassium nitrate, it is a clean and green product which having below listing features:

  • Environmentally friendly, which is ODP=0, GWP=0,ALT=0, little residue left after releasing, it is halon alternative.
  • It works without any pressure, it is non-pressurized system and pipe-less system.
  • It has a life span of more than 10 years, which is a long life circle.
  • High in fire extinguishing ability, its extinguishing density is about 100 to 150 gram per cubic meters.
  • Flexible and smart to install in any fields and industries, in many small, medium or large protection rooms and space.
  • Simple in structure and easy to install, it even can be operated by a non-technical person.
  • Not cause damage to machinery, facilities and other high-value equipment.
  • It has minimal Down times.
  • The aerosol forming agent is not limited by space and can bypass any obstruction to put out fire.

Aerosol suppression system has its advantages and features which other gaseous fire systems not have, all over the world many projects become to like to search for aerosol system as their first choice solution, as it mainly could be applied in the following fields, but not limits to:
Industrial, Off-shore, On-shore oil and gas, Government, Power generation, Telecommunications, Mining, Electrical cabinets and racks, Land transport, Marine, Warehouse, Computer Numerical Control  machines, ATM machines, Machinery, Financial institutions, Data centers, Cultural heritage (Archives, Museums), Manufacturing and storage facilities etc.

The aerosol system not only can total flooding the protection hazards, but also can direct-to-source local application, for example, in a computer room, we could install some large size of aerosol fire extinguishers for total flooding, and also can install some smaller size of aerosol devices in the electrical cabinets to offer local application.

But aerosol system is not suitable for the following locations:

  • Crowded place with a lot of people over there.
  • Metal hydride fires such as potassium hydrogen and sodium hydrogen
  • Fire of chemicals such as nitrocellulose, sodium nitrate etc.
  • Living metal fires such as potassium, magnesium, sodium, titanium, zirconium, and uranium etc.

Aerosol fire protection system start from Russia, some Russia companies develop the
potassium nitrate based aerosol suppression systems in 20th century, we called it the first generation of aerosol system; and from this period on some famous aerosol fire suppression manufacturers was built  up, we called them the second generation of aerosol system manufacturers; In China we are the earliest company to start to develop condensed aerosol based fire extinguishing system, furthermore, we produce the strontium nitrate based aerosol system, which is more clean and human friendly, we called our aerosol suppression system as the newest third generation of aerosol systems.

Till now, aerosol generators are very popular all over the world that some international organization have published their standard for it, such as: KIWA, ISO15779-2011 Aerosol General Requirement, CEN/TR15276-1, NFPA2010 and china GA 499.1-2010 etc, these standards shows aerosol system is recognized and recommended by official authorities, and could be applied in everywhere all over the world.

Many projects all over the world prefer to choose aerosol system, because it has incomparable advantages over other fire extinguishing systems, for details we welcome any of you to contact us and discuss the details.

Be AWARE of FIRE, Because we want the Earth to be free from fires.
