Electrical panel suppression
Self-contained units inside switchboards, control panels and cabinets, discharging into the enclosure the moment a fault starts to burn.

Most electrical fires start inside a closed box
A loose termination, a failing contactor or a rodent-damaged cable inside a panel burns for a long time before anything outside the enclosure notices. By the time a room detector sees smoke, the fault has taken the busbar with it — and the room system, when it discharges, has to flood the whole room to reach a fire in one cabinet.
Panel suppression puts the detection and the agent inside the enclosure instead. A tube or a detector inside the panel senses the fire where it starts, and a small charge of clean agent discharges into that cabinet alone. The result is a burnt termination rather than a burnt switchboard, and no discharge into the room.
These units are self-contained: no panel wiring, no releasing panel and no external power, which is what makes them practical to retrofit into an existing switchroom during a shutdown window. They can still be interfaced to the building fire panel so a discharge is reported rather than found later. We survey the boards, select the unit against each enclosure volume, install and interface them, and check them on the maintenance visit with the rest of the system.
What goes into a panel
Sized against the enclosure volume, one unit per cabinet or one manifolded unit across a board section.

Send the drawings or the BOQ and we will price it line by line. Most enquiries start with a site visit, because the site decides the system — not the catalogue.
