As the name indicates, flooding the entire hazard area with huge quantity of water (could be foam too) is known as deluge systems.

These systems are sometimes used for extinguishment, sometimes for control of fast spreading fires & sometimes as surface cooling. Applications are wide & mechanism of operation are also multiple like wet pilot actuation, dry pilot actuation, electrical actuation, manual actuation & these sometime combine with single pre action & double pre action thus making it again the need of skilled & experienced Engineers to understand, engineer & design the specifically required system for water or foam again by running multiple hydraulic calculations. Heba India again is proud to have a team of people who have designed, installed & successfully commissioned hundreds of such systems.
