Ensure uncompromising fire safety for your technologies. RQQD-01 is an advanced fire extinguishing device designed for automatic fire protection of switchboards. Thanks to modern aerosol fire extinguishing technology, the system can suppress an emerging fire at its very beginning, without the need for human intervention or electrical power supply.
The device works on the principle of chemical reaction of solid substances. Activation occurs completely automatically:
Thanks to its parameters, it is ideal for installation in critical systems where a conventional fire extinguisher would be impractical or dangerous:
Designed for reliability. See what makes the QRR series an industrial standard for miniature fire extinguishers.
Intelligent fire protection systems for larger switchboards. Connects to the cloud for continuous monitoring.
Protects power modules inside charging stands from heat loss.
Low-voltage switchboards, cabinets with circuit breakers and control panels. Installation on a DIN rail makes them perfect for additional installation.
Server racks and network cabinets. The aerosol is non-conductive and does not cause a short circuit on high-value servers.
Containers for lithium batteries and solar inverters. They operate in extreme temperatures (-50 °C), where gas systems fail.
When an electrical fire breaks out inside switchboards or control panels, every second counts - and so does every cubic centimeter of space. Device managers and safety technicians face a fundamental dilemma: traditional fire extinguishers offer proven reliability, but often at the cost of collateral damage, maintenance costs, and complex installation. Aerosol fire extinguishing devices promise a compact, automated alternative that protects sensitive equipment without leaving residues or using pressure vessels.
Aerosol fire extinguishing devices work on a fundamentally different principle than traditional fire extinguishers. When activated by heat (usually at 175 °C ± 5 °C), these units generate and release condensed aerosol particles - microscopic solid and liquid compounds, usually based on potassium - which interrupt the chemical chain reaction of the fire at the molecular level. The particles remain suspended in the air and interact with free radicals of combustion, thereby stopping oxidation without significant oxygen depletion.
Modern condensed aerosol systems, mounted on a DIN rail, have compact dimensions of 80 × 68 × 20 mm and provide fire protection coverage of up to 0.1 cubic meters. The fire extinguishing agent is released within 3-4 seconds through strategically located nozzles and floods the protected space with particles that suppress the fire. Unlike gas systems, aerosol generators do not require pressure vessels, external piping, or complex installation infrastructure.
This technology gained significance in the 1990s as an environmentally safer alternative to halon systems. The EPA approved condensed aerosols as acceptable replacements for halon 1301 for total flooding applications, recognizing their zero ozone depletion potential (ODP) and minimal global warming potential (GWP).

Traditional portable and fixed fire extinguishers include several different technologies, each with specific applications in fire classes:
ABC Dry Chemical Fire Extinguishers use a powder of monoammonium phosphate to create a barrier between fuel and oxygen and simultaneously interrupt the chemical reaction. They are effective for fires of class A (combustible materials), B (flammable liquids), and C (electrical equipment) and represent the most common type of multi-purpose fire extinguisher. However, the fine powder residues can be corrosive to electronics and difficult to clean.
CO2 (Carbon Dioxide) Fire Extinguishers displace oxygen and cool the fire using compressed carbon dioxide. CO2 is ideal for fires of class B and C, leaves no residues, making it suitable for server rooms and laboratories. However, limitations include ineffectiveness for class A fires, risk of asphyxiation in confined spaces, and potential for frostbite from the discharge.
Water-Based Fire Extinguishers (including water mist and foam) cool burning materials by heat absorption. Water-based fire extinguishers are highly effective for fires of class A, are cost-effective, and environmentally friendly. However, major drawbacks include unsuitability for electrical fires or fires of flammable liquids, potential damage to equipment by water, and risk of freezing in cold environments.
Each technology relies on pressure vessels, manual or automatic activation systems, and regular maintenance including pressure checks and agent replacement.
Understanding the basic technical differences helps identify which technology meets specific protection requirements.
Performance metrics reveal how each technology performs in actual fire conditions.
Data reveal the advantage of aerosol technology in protecting sensitive electronic devices in enclosed spaces, where residue-free operation and fast automated response provide critical protection without secondary damage.
Both technologies operate under different regulatory frameworks that govern design, installation, and maintenance.
Aerosol Extinguishing Standards:
Traditional Fire Extinguisher Standards:
Aerosol devices and quality traditional fire extinguishers have respective certifications (compliance with CE, UL, NFPA standards) that ensure regulatory acceptance in all jurisdictions.
Choosing the right fire extinguishing technology largely depends on the protected environment, fire risk profile, and operational constraints.
Scenarios for using aerosol fire extinguishers
Specifically for electrical distribution systems, it offers a 10-gram aerosol fire extinguisher mounted on a DIN rail, designed to match the shape and installation method of standard circuit breakers. This innovative design allows the fire extinguisher unit to be installed alongside electrical components in distribution cabinets, meter boxes, and control panels using the same rail-mounting system.
Measuring 80 × 68 × 20 mm and with a coverage capacity of 0.1 m³, the unit provides comprehensive protection for typical electrical distribution panels. Activation via a heat-sensitive cable (175 °C ± 5 °C) ensures an automatic response to fire without the need for external detection systems, while the flame-retardant ABS housing withstands operating temperatures ranging from -40 °C to +95 °C. The dual-sided nozzle placement allows for rapid and even distribution of the aerosol throughout the protected area.
Selecting the optimal fire suppression method requires an assessment of several decision-making factors:
Choose Aerosol Fire Extinguishing Devices When:
Choose Traditional Fire Extinguishers When:
Hybrid Approach:
Many facilities strategically implement both technologies – aerosol devices protect critical electrical infrastructure (distribution boards, server racks, control systems), while traditional portable fire extinguishers provide general coverage for corridors, offices, and open workspaces. This layered approach optimizes protection within various fire risk profiles.
While initial purchase price comparisons may favor traditional fire extinguishers, total cost of ownership reveals a different picture:
Specifically for the protection of electrical switchgear, aerosol devices offer excellent life cycle economy, as they take into account the prevention of collateral damage and reduced maintenance overhead.
Question: Are aerosol fire extinguishing devices safe for occupied spaces?
A: Yes, if properly specified. Modern condensed aerosol systems meet NFPA 2010 requirements for occupied space protection. Aerosol particles do not significantly reduce oxygen levels, although discharge may temporarily reduce visibility. In small enclosed electrical cabinets, human exposure is minimal since the device activates within sealed enclosures. Always verify product certifications and follow NFPA 2010 guidelines regarding room volume and ventilation requirements.
Question: Can aerosol devices replace all traditional fire extinguishers in a facility?
A: No. Aerosol technology excels in enclosed spaces for electrical equipment protection but loses effectiveness in large open spaces where particle dispersion occurs. Facilities should use traditional portable fire extinguishers for general fire response, especially for Class A fires in open spaces and situations requiring manual operation by personnel. Aerosol devices complement, rather than completely replace, traditional fire extinguishers.
Question: How long do aerosol fire extinguishers last before replacement?
A: Quality aerosol fire extinguishing units typically offer a 10 – 15 year lifespan with minimal maintenance. Unlike traditional pressurized fire extinguishers, which require regular replacement of the extinguishing agent and pressure testing, aerosol devices require only annual visual inspection to verify: (1) secure mounting without physical damage, (2) integrity of the thermal cable (no fraying or disconnection), (3) nozzle openings remain unobstructed, and (4) environmental conditions remain within operational range (-40 °C to +95 °C). After activation, the unit must be replaced since the aerosol-generating compound is consumed during discharge.
Question: What happens to sensitive electronics after aerosol discharge?
A: Condensed aerosol agents leave minimal residue – fine non-corrosive particles that can be cleaned using standard methods (dry cloth, compressed air, or HEPA vacuum). Unlike dry chemical powder (which is corrosive and requires special cleaning) or water (which causes immediate device failure), aerosol residue typically allows electronic devices to be restored to operation after basic cleaning. Some devices may continue to function without immediate cleaning, although thorough inspection after discharge is always recommended.
Question: Do aerosol fire extinguishers work for lithium-ion battery fires?
A: Aerosol devices can suppress fires in the early stage, including those involving lithium-ion batteries, before thermal runaway fully develops. However, once thermal runaway occurs, batteries generate their own oxygen, making fire extinguishing more challenging for any technology. In battery energy storage systems (BESS), aerosol devices work best as part of a multi-layered approach including thermal monitoring, early detection, and ventilation systems. They provide valuable protection against fires originating outside battery cells (electrical connections, enclosure components), which could otherwise initiate thermal runaway.
Question: What maintenance do aerosol fire extinguishers require?
A: Minimal. Annual visual inspection should verify: (1) secure mounting without physical damage, (2) integrity of the thermal cable (no fraying or disconnection), (3) nozzle openings remain unobstructed, and (4) environmental conditions remain within operational range (-40 °C to +95 °C). Over the 10 – 15 year lifespan, no pressure testing, replenishment of the extinguishing agent, or recertification is required. This is in stark contrast to traditional fire extinguishers, which require quarterly to annual professional inspection, pressure testing, and regular replenishment.
Question: Are aerosol systems more expensive than traditional fire extinguishers?
A: Initial procurement costs are comparable or slightly higher for aerosol units compared to traditional portable fire extinguishers. However, life cycle costs favor aerosol technology when considering: (1) eliminated maintenance costs (no pressure testing or replacement of the extinguishing agent), (2) prevented collateral damage (no damage to protected equipment from corrosive powder or water), and (3) reduced downtime after discharge. Specifically for electrical distribution board protection, aerosol devices typically offer lower total cost of ownership over their 10 – 15 year lifespan.
The choice between aerosol fire extinguishing devices and traditional fire extinguishers is not binary – it is application-specific. Aerosol technology brings unparalleled benefits for protecting electrical infrastructure, control systems, and sensitive equipment in enclosed spaces. The combination of automated response, residue-free operation, compact installation, and minimal maintenance makes aerosol devices an excellent choice for distribution boards, control panels, server racks, and similar applications where traditional fire extinguishers pose issues with space, residue, or response time.
Traditional fire extinguishers remain essential for general facility coverage, large open spaces, and situations requiring manual operation by personnel. The ideal fire protection strategy often combines both technologies – aerosol devices protect critical electrical assets, while traditional portable units provide comprehensive and accessible protection in occupied spaces.
For building managers and safety technicians specifying fire protection for electrical distribution systems, aerosol fire extinguishers mounted on DIN rails offer a specially designed solution that seamlessly integrates with standard electrical distribution board infrastructure. With a lifespan of over 10 years, automatic thermal activation, and safe operation for electronics, these devices represent a development in fire protection technology specifically designed for the unique challenges of modern electrical systems.
The question is not whether aerosol or traditional technology is "better" – but which technology best meets your specific protection needs, facility layout, and operational constraints. Understanding the technical differences, performance characteristics, and application strengths outlined in this guide enables informed decisions that optimize fire safety while minimizing life cycle costs and operational impact.
