In the last 10 years major developments have changed the ways of commercial cooking. Cooking equipment currently manufactured uses more efficient burners, resulting in much higher heating rates. More cooking is done with vegetable oil instead of animal fats. Vegetable oils have a much higher auto ignition temperature. Fryers are now made with improved insulation that slows the cooling rate, but which also increases the risk of a re-flash in the event of fire. Kitchen fires are much harder to extinguish than they were 10 or 20 years ago. The piranha hood system features fast flame knockdown with the power of a wet chemical suppression agent, and the cooling capability of water. Tests using the piranha double agent system have shown dramatically increased fire suppression system performance. The piranha hood system offers the following advantages: revolutionary wet chemical+water kitchen fire suppression systemtwice the coverage of conventional single-agent hood systemscools cooking oils 15 times faster than simple wet chemical kitchen fire suppression systemsflexible nozzle coverage compared to the older hood systemssmaller and fewer agent storage tanksplease note that changes by the national fire protection association (nfpa) to standard #10 now require a special "k class" hand portable fire extinguisher in cooking areas. See our nfpa #10 update for more information.
