Electric Panel Fire Suppression System
System Overview
Electric Panel Fire Safety Technology
Aurex Direct Low Pressure (DLP) fire suppression systems utilize heat-sensitive polymer tubing routed inside electrical panel enclosures. In the event of a localized fire or short circuit, the tube bursts at the hot point (138°C), releasing the clean agent directly onto the combustion source to prevent electrical fire progression.

System Components & Spares
Constructed using ISI-marked MS cylinders, direct low pressure valves, UL-listed FDT tubes, end of line adaptors, pressure switches, and clean agent fluids (FK-5-1-12 or HFC-227ea).
Key System Features
How DLP System Works
The linear detection tube is pressurized and holds the clean agent gas/fluid in check. When a flame makes contact with the tube or temperature rises to 138°C, the tube bursts. The resulting burst hole acts as a specialized spray nozzle, releasing the clean agent directly onto the source of the fire. The pressure drop in the tube can also actuate the pressure switch to trigger sounders or cut power to the panel instantly.
Typical Applications
DLP Micro-environment systems are typically used to protect electrical panel cabinets, server racks, and CNC tools where immediate localized suppression prevents larger facility-wide disasters.
