Pre-Engineered Novec 1230 marine suppression systems utilize Novec 1230 extinguishing agent, an electrically non-conductive, non-corrosive vapor that stops the combustion process by physical means.
Fire Suppression Systems
Upon discharge of the Pre-Engineered NovecTM 1230 fire suppression system, the extinguishing agent floods the compartment with an electrically non-conductive, non-corrosive vapor that stops the combustion process by physical means. NovecTM 1230 removes heat energy from the fire to the extent that the combustion reaction cannot sustain itself.
SEA-FIRE NovecTM 1230 fire suppression systems are designed to induce a minimum atmospheric concentration of 5.85% within the protected compartment.
