ADVANCED FIRE SUPPRESSION TECHNOLOGY

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.

01 / THE HIDDEN RISK

A Small Spark. A Hidden Fault. A Potentially Devastating Fire.

A loose connection, electrical arc or overheating component can become an ignition source inside an electrical cabinet.

In data centers and other critical facilities, faults may develop out of sight. A small, localized incident can lead to equipment damage, costly downtime or a much larger fire.

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.

01

Localized Heat

An electrical fault can generate abnormal heat inside compatible equipment.

02

Heat-Triggered Activation

Microcapsules respond when the product's designed activation threshold is reached.

03

Agent Release

Capsules release FK-5-1-12 clean agent near the heat source.

04

Clean, Localized Suppression

Residue-free and electrically non-conductive clean agent for localized supplemental fire suppression.
