One System for All Areas
Water mist systems offer the ideal middle ground between traditional sprinklers and gaseous fire suppression systems and can be used throughout the entire data center. But it’s important to remember: not all water mist-systems are equal. The quality of the suppression medium varies depending on the pressure levels and pump technology used – resulting in significant differences in water consumption and potential damage.
FOGTEC high-pressure water mist systems produce ultra-fine droplets, delivering highly efficient fire suppression while minimizing collateral damage.
With just a single pump, you can protect your entire data center – and in some cases, thanks to mobile pump units (FOGTEC SafetyUnit), even multiple buildings.

The system is designed as a pre-action setup with single- or double-interlock control. The protected area is divided into suppression zones, each activated via pre-action valves.
All pipework remains dry and unfilled with water until activation. The system triggers based on a two-detector dependency and only after thermal activation of nearby glass bulb nozzles. This ensures the system activates only at the fire’s point of origin, leaving other areas unaffected or minimally impacted.
Thanks to the thermal activation, the risk of false discharge is virtually eliminated.

FAQ – Fire Protection for Water Mist in Data Centers
Why are high-pressure water mist systems suitable for modular data centers?
Short answer: They atomize water finely, cool quickly, and use minimal water — effectively protecting IT equipment while being easily scalable across modules.
Note: System design (nozzle layout, pumps, detection) must be project-specific.Can they also protect energy storage systems (ESS)?
Short answer: Yes — water mist can remove heat and limit fire spread. FOGTEC provides specialized solutions for this purpose.
Note: Battery fire scenarios are complex and often require additional measures and testing.Are pressure relief panels or strict room enclosures still required?
Short answer: Not necessarily — water mist often allows simplified room concepts.
Note: Whether panels or enclosures can be omitted depends on the specific fire protection concept and applicable regulations.What is the FOGTEC SafetyUnit?
Short answer: A compact pump and control container that houses all fire protection components outside the modules (plug-and-play). According to your information, an autonomous version exists with up to 60 minutes of operation. Only piping and nozzles need to be installed on-site.
Note: The number of modules connected, actual runtime, and system performance must be verified for each project (datasheet / hydraulic calculation).
