Kidde Fenwal supplies engineered fire suppression and detection for high-hazard and mission-critical spaces — clean agent and CO2 systems, cylinders and valves, discharge nozzles and piping hardware, control panels and specialist detection.
These are system components rather than standalone products. A suppression installation ties together the cylinder and its valve assembly, the actuation hardware, the nozzles sized for the hazard volume, the pipe network, and a detection and release panel — and the parts are matched to one another by design calculation, not chosen independently.
When ordering replacements, work from the system drawings or the existing part numbers. Nozzle orifice sizing in particular is specific to the hazard it was calculated for and is not interchangeable between installations.
