Electrical enclosures, control panels, switchgear, and server racks are the nerve centers of modern commercial and industrial operations. They are also among the most common points of origin for devastating facility fires. Arc flashes, overloaded circuits, component degradation, and short circuits can instantly ignite a localized fire that, if left unmitigated, can spread into a catastrophic building-wide disaster.
DeFire USA designs, integrates, and deploys specialized Electric Cabinet Fire Protection Systems. These micro-environment solutions are engineered to detect and extinguish fires directly inside the enclosure at the precise point of origin—eliminating the threat in seconds without affecting the rest of your facility.
Traditional room-level suppression systems (like standard sprinklers or ceiling-mounted gas systems) will only activate after a fire has breached the electric cabinet and filled the room with smoke or heat. By that time, the internal electronics are completely destroyed, and operations are critically disrupted.
Our specialized cabinet systems utilize autonomous, flexible polymer detection tubing routed directly through the high-risk internal components of the enclosure. This provides two distinct, highly reliable methods of operation:
As regulatory landscapes evolve to eliminate persistent chemicals, SFFF represents the modern, 100% biodegradable, and eco-friendly standard for industrial fire protection.
The specialized detection tubing is pressurized with an eco-friendly clean agent. When a localized fire breaks out, the heat causes the tube to burst at the hottest point, forming a makeshift distribution nozzle.
The clean agent immediately floods the cabinet through that burst point, instantly extinguishing the fire at its source.
Smaller electrical cabinets, individual control panels, and localized server racks.
Polar solvents and water-miscible liquids naturally destroy standard firefighting foams by extracting the water layer from them. AR concentrates are uniquely engineered with polymers to combat this phenomenon.
The pressurized tubing acts purely as a linear thermal detection device. When the tube ruptures due to heat, it drops the system pressure, which automatically triggers a dedicated valve on a nearby storage cylinder.
The agent is discharged through strategically pre-engineered fixed nozzles installed throughout the top and sides of the enclosure, providing full volumetric coverage.
Large walk-in switchgear banks, complex motor control centers (MCCs), and multi-cabinet enclosures.
Because water or conductive materials cause total destruction when introduced to live currents, DeFire USA utilizes premium, non-conductive gaseous clean agents (such as FK-5-1-12 or HFC-227ea) for cabinet systems.
The gaseous agents extinguish the fire without causing sudden thermal drops that could warp or crack sensitive micro-circuitry.
The agent completely evaporates post-discharge, requiring zero cleanup and allowing your team to simply repair the faulty electrical component and reboot the system.
The discharge is completely safe for live, energized electrical components, preventing short circuits during mitigation.

A cabinet protection system must be flawlessly integrated into your facility’s wider safety ecosystem. At DeFire USA, we don’t just protect the cabinet—we engineer systems that communicate. Our installations feature pressure switches that integrate directly into your facility’s master fire alarm panel or SCADA systems, ensuring that the moment a cabinet system activates, power can be cut automatically to prevent re-ignition and your team is instantly notified.
