Heat-Activated Fire Suppression for Electrical Enclosures and Advanced Materials
FireXNull develops heat-activated microcapsule technology for localized, supplemental fire suppression in compatible electrical equipment and materials. Passive operation with no external power, sensors or wiring.
02 / THE FIREXNULL SOLUTION
Advanced Microcapsule Technology. Protection Where It Matters.
FireXNull uses heat-activated microcapsules containing FK-5-1-12 clean agent. When a product reaches its designed activation threshold, the capsules release the agent locally to provide supplemental fire suppression.
The technology is passive, with no external power, sensors, wiring or manual activation.

An electrical fault can generate abnormal heat inside compatible equipment.
Heat-Triggered Activation
Microcapsules respond when the product's designed activation threshold is reached.
Agent Release
Capsules release FK-5-1-12 clean agent near the heat source.
Clean, Localized Suppression
Residue-free and electrically non-conductive clean agent for localized supplemental fire suppression.
Designed as supplemental protection. Not a replacement for code-required fire protection systems. Review applicable technical data sheets →
