FIRE EXTINGUISHING WITH AEROSOL GENERATOR

water aerosol products

Stat-X systems provide a highly effective suppression of fires in confined or local areas. This applies to all of the aerosols, that are, in fact, one of the most effective extinguishing technologies available. Each and every aerosol systemis effective in extinguishing fires. They are all similar in this sense, yet they are all different.

Beyond that, however, between aerosol generators and manufacturers there are important differences related to efficacy - the amount of agent required; the size of the generated particulate; aerosol composition (gas particulate mixture); chemistry - in addition to the basic KNO3; sub-products generated; cleaning; toxicity; quality - materials and production methods; design - with computer-aided design, experience in the field of fire protection; services; training; certifications.

Aerosol extinguishingtechnology was originally developed by the aerospace industry. Nowadays, after years of research, it is a valid substitute to gaseous extinguishing agents which are found in the majority of applications. Its innovative technology allows the protection of at-risk environments without having to install pipes and cylinders. The result is a safe and inexpensive fire extinguishing system, which is easy to install and maintain.

aerosol generator operation
Operation:

An aerosol generator is an autonomous extinguishing unit that contains a form of aerosol compound, which, during a controlled combustion process within the generator, produces an extinguishing agent of ultra fine aerosol that is significantly more effective than the alternatives which are currently available.

The units are made of stainless steel, are approved both for area and for volume coverage and do not require piping, nozzles or other distribution equipment.

A stable solid charge of aerosol which forms the composition is contained within the generator. Upon activation of the actuator, the charge begins a controlled burning producing an ultra-fine aerosol. The aerosol passes through a series of oxidation and cooling filters, where the aerosol temperature is rapidly reduced before it overflows through the outlet holes of the low-pressure generator.

The placement of the generator inside the danger zone provides adequate flow and distribution of the aerosol within the protected volume.

Mechanism of suppression:

  • the primary mechanism of suppression is based on the chemical interference with the free radicals of the flame
  • interrupt the spread of fire
  • dilution of the medium with flammable inert gases
  • cooling

The radicals of "propagation" are essential elements in the development of the fire: OH, H and O.

Stat-X suppresses the fire (primarily) by chemical interference with these free radicals inside the fire zone - thus interrupting the reaction of the ongoing fire.

Potassium (K) is the main active component in the Stat-X aerosol.

They are particularly active and react with these "radials of propagation" which are very similar to how the bromine radicals act in Halon.

The chemical reaction can be represented as follows, for example:
K + OH = KOH
KOH + H = K + H2O
K +OH, etc...

Moreover, the radical propogation of the flame recombines on the surface area of ​​the ultra fine aerosol particulates to further interfere with the propagation of the flame:
O + H = OH
H + OH = H2O

As a result, Stat-X ensures extremely reduced suppression timelines.

StatX

  • flammable at 1200 ° C
  • uses quality chemical reagents - 99.5% + pure (consistent)
  • size of the average ultra-fine particle - 2.1 µm (clean, efficient)
  • output 75% - 85% of the initial mass (efficiently)
  • It produces 70% aerosol, 30% gas (effective suppression)
  • hermetically sealed (stable over time - moisture does not penetrate)
  • physical refrigerant (no negative chemical interaction with the aerosol)
  • very cool average maximum temperature of output at 24-inches 75 °C

Stat-X fire suppression systems have been tested and certified to conform with the Standard UL 2127 for Inert Gas Clean Agent Extinguishing System Units. Due to their fast response time, low fire extinguishing concentration, and environmental safety, Stat-X fire suppression systems may be used in critical applications across a wide range of industries. Aerosol generators are currently protecting and are suitable for use in:

Typical applications:
  • telecommunications
  • storing flammable liquids
  • data processing
  • Marine engine rooms
  • process control rooms
  • mobile equipment of great value
  • energy plants

STATX FIRST RESPONDER

AEROSOL EXTINGUISHING SYSTEMS

Personal fire device

StatX - First Responder

First Responder® is a new and innovative tool designed to aid in the suppression of fires and for use as a personal protection device for fire fighters in emergency egress or entrance situations. It is physically and functionally similar to a smoke grenade, with the fundamental difference that it delivers Stat-X, a highly effective aerosol fire suppression agent.

The primary aim of First Responder is for use as an extremely effective device to suppress and limit the development of fire until such a time as traditional methods are available.

First Responder is typically used in the following scenarios:

1. The police arrive at the site of the fire in its initial stages. After evacuating people and before firefighting personnel can arrive at the scene, they toss a Stat-X First Responder into the rooms which are involved with the fire in order to gain time before the arrival of a firefighting crew.

2. Firefighters are concerned about potential flashover from a fire down a hall and water isn't available yet. By tossing a Stat-X First Responder they eliminate many of the factors that contribute to the flashover.

3. A firefighter is trapped or can't get to a victim due to an intense fire zone. Tossing a Stat-X First Responder into the flames has an immediate fire suppression effect.

Extensive testing has demonstrated significant suppression effects in volumes of about 20 m3. More units are required for larger volumes or areas with excessive loss. Given the "buoyant" nature of the aerosol, in the case of high ceilings, a greater amount is required. First Responder is most effective when it is launched in the immediate vicinity of the fire.

Once launched on the flame, the unit remains completely intact and discharges the aerosol in a circular fashion in a total time of 20 sec. First Responder does not reduce the oxygen levels as it extinguishes the fire by base chemical interference without modifying the atmosphere. The unit is not pressurised prior to activation.

When activated, a controlled combustion reaction converts the solid into an aerosol compound composed of 30% inert gases (primarily nitrogen and small amounts of water vapour) and 70% of ultra fine particles (potassium compounds of 1-2 microns in size). The unit operates at relatively low pressure. The compound is made from a patented mixture of potassium nitrate, dicyandiamide and an organic binder, the same used for the whole range of Stat-X products which are certified by UL Canada and used throughout the world. The compound has been approved by the United States Environmental Protection Agency.

With regard to the use of First Responder in open spaces, the aerosol dissipates quickly because of the ultra fine size of the particles. Unlike a fire extinguisher which employs ammonium phosphate there is no covering effect and there is no cooling effect as with water. The aerosol is most effective when used in relatively confined spaces.

First Responder® is an innovative product, the first test samples were completed in July 2006 with a commercial launch in September 2006. Similar products do not exist.
