Aerosol Fire Extinguishing Technology

An innovating, clean and economical extinguishing agent

In the range of the new generation of extinguishing agents, an innovative product is now available for realization of effective fire-prevention systems. It’s economical and totally ecological: type S aerosol which can be classified as an extinguishing agent that belongs in the category of the dry powder, commonly used in portable fire extinguishers.

By definition, an aerosol is a system of solid or liquid particles that are suspended in a gaseous environment.

How aerosol works

The condensed aerosol extinguishing agents (resulting from implementation of generators) are formed by tiny solid particles of alkaline metals salts (about 40% of the weight of the generated aerosol) and gas (about 60% of the weight of the generated aerosol), mostly N2, CO2 and vapor.

Aerosol extinguishes fire through chemical working, interfering with the chain reaction of combustion, removing the free radicals (they aren’t disposable any more for banking up combustion). Physically, the aerosol takes energy from the combustion environment (cooling action). These two reactions occur mainly on the surface of solid aerosol particles; therefore, the more particles are little, the larger surface of reaction is available, the more effective is extinguishing action.

Aerosol is a cost effective alternative to halon. Using the very latest generation of stable non-pyrotechnic, type S aerosol-forming compound which upon activation transforms into a rapidly expanding, highly efficient and highly effective extinguishing aerosol (1 gram creates 0.5 liter of aerosol gas). Based on strontium salts, the strontium molecules in aerosol attack the fire physically and chemically, inhibiting the chain chemical reaction present in combustion.

Where aerosol installation possible

The extinguisher is suitable for fighting fires in closed environments, where the risk is caused by the presence of：

• Solid combustible material as woods, papers, cloths, composed materials, plastic material and other such things
• Liquid combustible material as oils, gasoline and other such products resulting from the refining of petroleum, organic solvents, resins, etc.
• Electrical and electrical appliances, even under live tension, u to 20LV, for example low tension electrical switchboards, dry or oil transformers, cable tunnels, cable shafts, transformation and distributing carbines, telephone

Safety Instructions

The extinguishing aerosol is essentially made of tiny solid particles of oxides and sulphates from alkaline metals, therefore:

• The aerosol is not dangerous for the human beings
• It doesn’t corrode or damage other materials
• Removable with common vacuum cleaner
• Wash away with fresh water
