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
An Added Layer of Protection for Hidden Electrical Risks.
FireXNull adds localized, heat-activated fire suppression inside compatible electrical enclosures—bringing an additional layer of protection close to potential ignition points.
Microcapsules release FK-5-1-12 clean agent when the product reaches its designed activation temperature.
See how it worksHeat-Activated
Microcapsules respond at the product’s designed temperature threshold.
Localized Suppression
Agent releases near the heat source for supplemental suppression.
No External Power
Operates without batteries or an electrical supply.
No Sensors or Wiring
Passive operation without detection electronics or control wiring.
Residue-Free Clean Agent
FK-5-1-12 leaves no agent residue in intended use.
Electrically Non-Conductive
The extinguishing agent does not conduct electricity.
Designed as supplemental protection. Not a replacement for code-required fire protection systems. Review applicable technical data sheets →
