Pentair, a global industrial company, offers the first two hour UL/ULC listed fireresistant system. First invented in 1896, and first produced commercially as ‘Pyrotenax’ in 1936, today this critical technology is utilized world-wide for the safe evacuation of buildings and for continued operation of firefighting equipment.
“Our UL 2196 Listed Pyrotenax System 1850 Mineral Insulated (MI) Fire Rated Wiring ensures a minimum of two hours of electricity to critical emergency and life-saving equipment in the event of a fire,” Brad Faulconer, VP & GM, Pentair Thermal Building Solutions. In 2012, all listed fire-resistive cables were de-classified by UL following research conducted on polymerinsulated fire-resistive cables, some of which showed a high failure rate under fire-test conditions. Since that time, UL conducted testing on Pentair’s Pyrotenax Mineral Insulated cables, which utilize a different technology than polymer-insulated cables and are constructed of non-combustible, inorganic materials. UL concluded that Pentair’s cables were not subject to the failure modes found in the research testing. This reinstatement was the first in the industry.
This system can be found globally in hospitals, tunnels, subways, airports and high rise buildings. They protect fire alarm wiring, fire fighting systems, elevators and places of public assembly where fire protection of critical circuits is required. Unlike conventional cables, the Pyrotenax System 1850 MI wire consists of solid copper conductors in a continuous copper sheath with magnesium powder insulation, without needing a conduit for protection. With an all inorganic construction, there will be zero smoke or flame spread if a fire breaks out.
Stop by NFPA Booth 811, June 13-16 at the Las Vegas Mandalay Bay Convention Center, for one on one conversations to explain further how this mineral insulated cable can operate continuously at 482°F. Also on display is Pentair’s FM7745 approved TraceTek Fast Fuel Sensors and NFPA 13, CSA and UL Certified and Listed Raychem XL-Trace Self Regulating Heating Cable for Fire Suppression Systems.
