Deluge Fire Systems use open nozzles and a deluge valve so that water, or foam, discharges from every nozzle at once when the detection system trips. They protect high-hazard areas such as fuel loading bays, transformers and conveyors.

Deluge Fire Systems FAQs
What is the difference between deluge and sprinklers?
Sprinkler heads open one by one with heat. Deluge nozzles are open, so the whole area is wet at once.
Do deluge systems use a lot of water?
Yes. Large storage and pumps are usually needed.
