Which foam-water system is designed to use nozzles rather than sprinklers?

Some foam-water systems are built to distribute foam-water through spray nozzles, not through conventional sprinkler heads. This design uses nozzle-specified spray patterns to blanket the hazard area with foam-water, providing effective fuel dilution and cooling over a broad, irregular, or large space where a sprinkler head pattern wouldn’t optimize coverage. That is exactly what a foam-water spray system is designed to do—deliver foam through spray nozzles rather than through standard sprinklers. The other foam-water configurations rely on sprinkler-type devices (open or enclosed heads, or dry pipe/preaction arrangements that release water to sprinklers) rather than dedicated spray nozzles, so they don’t fit the described design.
