Victaulic Vortex

• Hybrid Fire Extinguishing System (FM 5580):

– System of nozzles delivering Hybrid Media intended to control, suppress, or extinguish fires.• Victaulic Hybrid Media

– All natural• Nitrogen• Water

Victaulic Vortex

• As an inert gas – Atmosphere by volume

• 78.1% N2• 20.8% O2

– Addition of Nitrogen gas to an enclosure• Oxygen dilution

– Below 15%

• As water mist – Water

• Heat Capacitance• Vaporization

Victaulic Vortex– Recap

• A Hybrid system Incorporates the best of:– Inert gas system– Water Mist system

• Inert Gas Strengths – Effective for small fires– Attacks the oxygen of the fire triangle– Green system– Fewer nitrogen cylinders– Inexpensive gas replacement

• Water Mist Strengths– Very effective on large fuel based fires– Attacks the heat of the fire triangle– Low pressures– No high pressure pumps
