AEROSOL DSPA

An automatic DSPA extinguishing system combines the innovation in the way DSPA aerosol generators work with the reliability and safety of a certified extinguishing panel. It is a fully certified, safe, reliable and automatic extinguishing solution, which can be used in many applications such as server rooms, warehouses, archives, etc.

Activation of DSPA generators, in the event of a fire, is done automatically through a command given by the extinguishing panel, in accordance with the requirements of EN 15276 and ISO15799 standards.

The extinguishing material aerosol DSPA in aerosol form, consists of fine and ultrafine particles of alkali metal salts dispersed in gases consisting mainly of nitrogen, carbon dioxide and water vapor. It is produced through an oxidation reaction (exothermic reaction) from the solid charge contained inside the DSPA aerosol generator, without being under pressure.

The DSPA aerosol is a non-conductive medium, and having a volumetric effect it spreads throughout the volume of the protected space. The DSPA aerosol remains in natural suspension for a certain period of time, depending on the tightness of the space, and then if the space is not ventilated, the aerosol particles settle in the form of ultrafine dust, in a very small amount.

DSPA aerosol in both solid charge and aerosol form is friendly to humans, animals and the environment.

HOW IT WORKS

Fire is a combustion reaction, during which specific reactions take place between oxygen, the gases of the burning matter, the heat present in the flame and finally the free radicals.

Free radicals are unstable compounds produced (mainly O∙, H∙ and OH∙) that are created during fire and are essentially oxygen compounds that contain unpaired electrons, which is why their extremely high activity is due to them.

These reactions take place in an evolving way as a chain reaction, which results in the development and spread of the fire.

The extinguishing action of the aerosol is based precisely on the interruption of the chain reaction that takes place during the fire, since the potassium compounds contained in it, having a very low ionization energy, bind the produced unstable free radicals to form the stable compound KOH, as a result of which it is suppressed the oxidation chain reaction and thus the growth and spread of fire.

During extinguishing the DSPA aerosol does not bind oxygen and thus the concentration of oxygen in the protected space practically does not change.

The concentration of the aerosol in the protected space after extinguishing additionally protects the space from possible re-ignition of the fire without causing any damage to the protected equipment.
