anfrage@degesa.deThe primary extinguishing effect of aerosol fire suppression systems is based on the interruption of the chain reaction that takes place during combustion. The Stat-X extinguishing system does not displace oxygen, does not build up pressure and is harmless to people and the environment.
Fire requires the right proportions of oxygen, combustible material and heat to develop. The primary effect of aerosol fire suppression systems is based on the interruption of the chain reaction that takes place during combustion and not on oxygen displacement.
Stat-X® aerosol fire suppression systems produce a highly effective and technologically advanced extinguishing agent with unique operational and functional characteristics. They combine an environmentally friendly and non-hazardous agent with highly effective extinguishing properties.
The result is firefighting in the early stages, less damage to plant, equipment or buildings, significantly shorter production downtimes and cost efficiency in preventive fire protection.
The aerosol extinguishing agent spreads like gas, only without toxic properties, without oxygen displacement and is suitable for use in permanently occupied rooms. The extinguishing generators are made of stainless steel, operate without pressure and have a service life of up to 20 years.
Stat-X® aerosol fire suppression system requires the lowest concentration of extinguishing agent compared to all other systems and is therefore the most efficient aerosol fire suppression system on the market.
The extinguishing aerosol is unique. A special solid chemical that, when ignited electrically, thermally or manually, produces combustion products – micrometer-sized dry particles (mainly potassium carbonates) and a gaseous mixture (mainly carbon dioxide, nitrogen). These are mixed to form a uniform fire extinguishing aerosol before being discharged from the generator.
The aerosol-forming chemical is a thermoplastic mixture consisting of an oxidizing agent and a flammable binder which, when activated, produces combustion products – micrometer-sized dry suspended particles and a gaseous mixture. These are mixed to form a uniform fire extinguishing aerosol before being discharged from the generator.
The hot aerosol propels itself through a solid chemical coolant, which decomposes and absorbs large amounts of heat. The extinguishing agent emerges from the generator having cooled down considerably.
The reaction temperatures inside the generator are high, so that the potassium carbonates are formed in the gas phase, but change to the solid state as they cool down. As the solid potassium carbonates are produced by condensation, they are also referred to as a condensed aerosol.
The micrometer-sized suspended particles have gas-like three-dimensional properties that allow them to spread homogeneously even in the most remote areas. Homogeneous distribution is achieved within a few seconds, and the long holding time of the aerosol helps to prevent the fire from flaring up again.
The patented solid compound produces the unique Stat-X extinguishing agent in a combustion reaction. The production processes and chemicals used have a direct influence on the purity of the solid compound and the quality of the extinguishing agent.
The chemical coolant decomposes and absorbs large amounts of heat. The extinguishing agent is thus condensed and cooled down considerably. In addition, large solid particles are filtered out.
The reaction temperatures inside the generator are high, which is why an insulation layer is used to insulate the outer stainless steel layer of the generator as well as possible.
All Stat-X® Extinguishing generators consist of a high-quality stainless steel housing. The world’s largest militaries have chosen Stat-X for its robustness and manufacturing quality.
The outlet openings are sealed with a ceramic foil to protect the inside of the generator even at high temperatures and high humidity.
We select the right combination of extinguishing generators depending on the room size and conditions. The objective is to achieve a homogeneous spread of the extinguishing agent in the room as quickly as possible. As a rule, it makes sense to install several smaller generators, even if theoretically one large unit would release sufficient extinguishing agent.
To ensure the necessary triggering current for the extinguishing generators, they are triggered in quick succession. Our sequential actuators are used for this, which always trigger two extinguishing generators and then switch through to the next system coupler.
Connection of e.g. higher-level fire alarm systems, air conditioning systems, etc.
Depending on their design and characteristics, raised floors and ceilings can be considered as separate extinguishing zones or together with the main room. The easy integration of Stat-X allows installation directly in the danger zone.
The Stat-X aerosol generators can be integrated directly into the control cabinet or devices to detect and extinguish fires in the early stages. These can then be considered as a separate extinguishing area and extinguished individually as the first escalation stage.
Stat-X® Extinguishing generators of the E series are triggered electrically and can be combined with any conventional fire alarm system. They are available in eight different sizes.
The EX models, certified for EX zone 2, are electrically powered aerosol generators for use in closed environments classified as potentially explosive atmospheres.
Stat-X® Extinguishing generators of the T series are triggered thermally and/or manually with their own detection and ignition device. They are therefore stand-alone systems that are particularly suitable for cabinets and enclosures. Purely manually triggered systems are activated manually via a pull cord. This makes this form of triggering particularly suitable for applications in which people have to decide whether and when extinguishing is triggered.
The Stat-X First Responder is a small, lightweight, pull-activated hand tool that can be used in confined spaces for immediate firefighting. The Stat-X First Responder is an exceptional tool for underground vaults, mining, shaft fires etc. or for emergency services, plant fire departments and first responders who have to cut a path through walls of flames to open up escape routes.
Aerosol fire suppression systems are a relatively new technology about which there is still little information available compared to other extinguishing systems. degesa has been the number one contact for aerosol fire suppression systems for more than 15 years and is the exclusive partner for the world’s leading quality Stat-X® aerosol fire suppression system.
"Is the aerosol extinguishing agent life-threatening?"
No, a professionally planned and installed aerosol fire suppression system poses no danger to people. No dangerous quantities of toxic substances are released when triggered. However, it should be noted that the extinguishing agent is highly opaque. Employees who are present in the extinguishing area must be instructed.
"Are all aerosols the same for aerosol fire suppression systems?"
Definitely not! Every manufacturer of aerosols for fire suppression systems has its own formulation. Some are therefore more effective than others, based on the required aerosol quantities (in grams) per cubic meter of room volume specified by the manufacturer. The UL-listed Stat-X® aerosol fire suppression system requires the lowest concentration of extinguishing agent for Class A, B and C fires of all internationally known aerosol fire suppression systems and is the first to be approved for Zone 2 hazardous areas.
"Are there applications for which aerosol fire suppression systems are not suitable?"
Aerosol fire suppression systems are particularly advantageous in industrial applications. We recommend avoiding the use of aerosol fire suppression systems in escape routes and public areas, as there is considerable visual impairment when they are triggered, which is unsuitable for an organized evacuation without panic. If fire suppression systems are installed in occupied or normally unoccupied rooms, the release of the extinguishing agent must be delayed in accordance with the evacuation time.
"Are aerosol fire suppression systems dangerous for servers, hard drives or sensitive devices?"
No. As the Stat-X extinguishing agent is not electrically conductive, does not adhere and does not attack surfaces, it does not cause any damage to appliances. The extinguishing agent can be easily removed with compressed air, for example.
"How much residue remains after triggering the Stat-X® aerosol fire suppression system?"
The residue after triggering depends on how quickly the room is ventilated. Assuming normal holding times of 15-20 minutes until the flooded room is vented, the residue is minimal and can be removed with very little effort.
"What advantage do Stat-X® aerosol fire suppression systems have over conventional extinguishing systems?"
Aerosol fire suppression systems differ from conventional extinguishing systems in many ways. Depending on the application, different points are therefore advantageous.
Further application-specific advantages of Stat-X® aerosol fire suppression systems can be found on the corresponding pages of the application areas.
"How expensive are Stat-X® aerosol fire suppression systems?"
As each fire suppression system is individually planned by us and also installed as required, we cannot make any general price statements. We will be happy to help you with this in a personal meeting and give you an initial guideline as soon as we know the key data for your project.
Aerosol fire suppression systems are very cost-effective due to the low installation and maintenance costs and the extremely small amount of extinguishing agent required. Stat-X® aerosol fire suppression systems require the lowest concentration of extinguishing agent of all internationally known aerosol fire suppression systems.
"Can Stat-X® aerosol fire suppression systems be retrofitted?"
Yes, our fire suppression systems can be easily retrofitted in most cases. Thanks to our many years of experience with aerosol fire suppression systems, we will work with you to find a suitable solution. Thanks to the large selection of different extinguishing generators, triggering options and compatibility with every fire alarm control panel, a concept can be developed for almost any application.
"Who will design, install and maintain my Stat-X® aerosol fire suppression system?"
The Stat-X fire suppression system is designed by our specialist staff. Due to the extremely simple and minimally invasive design of the aerosol fire suppression systems, installation and maintenance can be carried out either by us or by your own personnel under our guidance. We are of course available with all our expertise.
