Deluge System vs. Sprinkler System

Understanding the Difference

In fire protection engineering, Deluge and Sprinkler Systems may look similar from the piping side, but their operating philosophy is completely different.

Deluge System

A Deluge System uses open nozzles/sprinklers, with no heat-sensitive element sealing each outlet. The piping network is normally dry until the Deluge Valve is activated by a separate detection/releasing system.
