A replacement for halon (halomethane) was called for: a fire-extinguishing agent that combats fire at a chemical level, is environmentally friendly, has no or only a low ozone-depleting potential (ODP), is non-toxic to humans and does not damage equipment.<\/p>\n<p>Aerosol fire suppression systems achieve this by producing a highly effective and technologically advanced extinguishing agent with unique operational and functional characteristics. They thus combine an environmentally friendly and non-hazardous extinguishing agent with highly effective fire-suppression properties.<\/p>\n<p>The result is fire suppression in its early stages, reduced damage to machinery, equipment and buildings, significantly shorter production downtime, and cost-effectiveness in preventive fire protection.<\/p>\n<p><strong>Definition<\/strong><\/p>\n<p>A condensed aerosol is defined as an extinguishing agent consisting of finely dispersed solid particles and gaseous substances produced during the combustion of a fixed substance. The US National Fire Protection Association (NFPA) defines condensed aerosols as suspended particles with a diameter of less than 10 micrometres. Due to the small particle size, large reaction surfaces are created, which are crucial to the effectiveness of the extinguishing agent.<\/p>\n<p>Aerosol extinguishing technology has its origins in the aerospace industry. There is no place where maximum reliability and efficiency are more important than in space. The answer to these specific challenges was found in condensed potassium carbonate, suspended in a gaseous mixture \u2013 the first aerosol extinguishing agents were born.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-1021\" src=\"http:\/\/degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-300x212.jpeg\" alt=\"\" width=\"528\" height=\"373\" srcset=\"https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-300x212.jpeg 300w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-1024x724.jpeg 1024w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-768x543.jpeg 768w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-1536x1086.jpeg 1536w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-2048x1448.jpeg 2048w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-400x283.jpeg 400w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-919x650.jpeg 919w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-40x28.jpeg 40w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-53x37.jpeg 53w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-707x500.jpeg 707w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-566x400.jpeg 566w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-424x300.jpeg 424w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-30x21.jpeg 30w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-100x71.jpeg 100w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-600x424.jpeg 600w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-283x200.jpeg 283w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-474x335.jpeg 474w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-68x48.jpeg 68w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-727x514.jpeg 727w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-452x320.jpeg 452w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-192x136.jpeg 192w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-120x85.jpeg 120w, https:\/\/www.degesa-fire-systems.de\/wp-content\/uploads\/2025\/02\/Webb_Liftoff_on_Ariane_5_potm2201a-339x240.jpeg 339w\" sizes=\"auto, (max-width: 528px) 100vw, 528px\" \/><\/p>\n<p>Just like the solid rocket booster of the Ariane 5 rocket, the extinguishing agent is produced and installed as a solid chemical.

Leading aerosol suppression systems require less than a tenth of the extinguishing agent volume per cubic metre of protected space compared to the most effective extinguishing gases.<\/p>\n<p><strong>Value for money<\/strong><\/p>\n<p>Thanks to the high efficiency of the extinguishing agent and the fact that there are no additional costs for the installation and maintenance of pipework, pressure measurement systems, etc., aerosol fire suppression systems offer excellent value for money compared to other fire suppression methods. When one considers the risk of damage to buildings and equipment posed, for example, by water-based extinguishing systems, the advantage becomes all the more significant. When <strong>properly installed and planned<\/strong>, aerosol extinguishing systems cause no damage to buildings or equipment!<\/p>\n<p><strong>Environmentally friendly<\/strong><\/p>\n<p>Aerosol fire suppression systems have no greenhouse potential and do not deplete the ozone layer. They are 100% PFAS-free.<\/p>\n<p><strong>Non-hazardous<\/strong><\/p>\n<p>Aerosol fire suppression systems do not displace oxygen. The leading-quality aerosol fire suppression systems are also non-toxic. Consequently, the extinguishing agent poses no immediate danger to humans. It should be noted that, upon activation, the extinguishing agent forms an opaque cloud of mist in the area, which may impede the evacuation of people. The systems are therefore designed to activate with a delay and are triggered by an evacuation alarm.<\/p>\n<p><strong>No pressure relief required<\/strong><\/p>\n<p>A major challenge for operators wishing to install a gas extinguishing system is often the pressure relief required for this purpose. Aerosol extinguishing systems do not build up any significant pressure in the room, which is why no pressure relief is necessary. This is a particular advantage for IT rooms and storage rooms in basements where an extinguishing system needs to be retrofitted.<\/p>\n            \t\n\n                    <\/div>\n    ","protected":false},"excerpt":{"rendered":"","protected":false},"author":4,"featured_media":1815,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-2027","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-neuigkeiten"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>What are aerosol fire suppression systems? | degesa fire systems gmbh<\/title>\n<meta name=\"description\" content=\"Find out more about aerosol fire supression systems.
