Data centers form the core infrastructure of the digital society. As the demands for security and service availability grow, the importance of reliable fire protection of data centers becomes increasingly critical. Even a minor fire can lead to serious outages, data loss, reputational damage, and high financial costs.
Modern data centers therefore require a specialized, multi-layered approach to the fire protection of data centers — from early detection to effective and technologically gentle extinguishing systems.
Fire Risks in Data Centers
Although data centers are designed with a strong emphasis on safety, they are not immune to fire risks. The most common causes include:
Short circuits and faults in electrical installations – especially in distribution panels and UPS systems.
Overheating of equipment – due to poor ventilation or cooling system failure.
Failure of cooling circuits – leading to thermal overload of IT infrastructure.
Human error – such as improper handling, maintenance during operation, or storing flammable materials.
According to the NFPA (National Fire Protection Association), up to 29% of data center fires originate in electrical installations. And when an outage occurs, the consequences are immediate: according to research by the Ponemon Institute, the average cost of one minute of data center downtime ranges from $9,000 to $17,000.
Furthermore, according to the Uptime Institute, up to 24% of data center outages are related to failures in electrical infrastructure, with fire being a major contributor. While fire protection often focuses on visible equipment, in practice, as much as 60% of facilities underestimate the protection of underfloor voids and cable ducts — areas where a fire is most likely to spread first.
Prevention and Multi-Layered Protection of Data Centers
An effective fire protection system must be built on a combination of:
Early smoke detection,
Automatic and technology-friendly extinguishing (e.g. gas-based systems),
Passive measures (fire partitions, cable and pipe penetrations),
Regular maintenance and staff training.
Given the risks and the high costs associated with even short outages, the focus is especially on rapid response without damaging critical equipment.
Air Smoke Detection – SECURITON FIRE ASD
Fixed Fire Extinguishing System – Water Mist VID FireKill
One of the most reliable solutions for early fire detection in data centers is
ASD (Aspirating Smoke Detection) by the Swiss company SECURITON.
Advantages of the SECURITON ASD system:
High sensitivity – detects even very small amounts of smoke.
Suitable for demanding climate conditions with high air circulation.
Flexible installation – underfloor, in racks, on ceilings.
Low rate of false alarms.

Modern data centers require extinguishing systems that do not damage sensitive equipment. That’s why low-pressure water mist VID FireKill is emerging as an optimal solution – extinguishing fire with minimal water and no secondary damage.
Key advantages:
Very low water consumption – protects equipment without flooding.
Safe in the presence of electricity – water is in microdroplet form.
No need for hermetic sealing – works even with open doors.
No gas bottles or pressurized tanks – easier installation and maintenance.
Eco-friendly solution – no chemicals or gases with climate impact.
Comparison: Water Mist vs. Gas Suppression Systems
In practice, the most common comparison is between water mist and gas-based suppression systems (e.g. FM-200, Novec 1230, Inergen). Each solution has its specifics, but in terms of flexibility, cost, and ecological impact, water mist is becoming increasingly advantageous.
| Criterion | Water Mist (VID FireKill) | Gas Suppression (FM-200, Novec 1230) |
|---|---|---|
| Equipment damage | Very low (fine droplets) | None (dry medium) |
| Functionality in open space | ✅ Yes | ❌ No (requires airtight sealing) |
| Water/gas consumption | Minimal | High (requires cylinder filling) |
| Environmental impact | None – water as the medium | Possible (e.g. GWP for FM-200) |
| Operating costs | Lower | Higher operational costs |
| Servicing & logistics | Simple | More demanding – pressurized tanks |
International Certifications and Insurance Confidence
SECURITON FIRE ASD and VID FireKill technologies comply with the strict standards of international certification authorities such as VdS (Germany) and FM Global (USA).
VdS is one of the most renowned European institutes for safety technologies, focused on fire protection system testing and certification. FM Global, one of the world’s largest industrial insurers, certifies only systems that demonstrably reduce fire risks in practice.
Thanks to these certifications, solutions like SECURITON FIRE ASD and VID FireKill are globally accepted by insurance providers, who often require them as a condition for insuring high-value data center infrastructure. These certifications are not just formalities — they serve as a guarantee of reliability, functionality, and reduced insurance risk in the event of fire.
Conclusion: Innovation in Safety Services
The risk of fire in a data center is real, and the consequences can be fatal. The combination of precise detection with SECURITON ASD and gentle suppression using VID FireKill water mist represents one of today’s most eco-friendly, reliable, and cost-efficient solutions.
