ASHLAND, Mass. — UTC Climate, Controls & Security Systems company Marioff Corp., a developer of water mist fire protection technology, announced that its HI-FOG water mist fire protection system has received Underwriters Laboratory (UL) listing for use in Ordinary Hazard Group 1 (OH1) applications. The product has also earned Factory Mutual (FM) Light Hazard (LH) system approval.
“HI-FOG is a proven technology that has been successfully fighting fires for more than 20 years,” Marioff General Manager Lance Harry says. “Receiving UL OH1 listing means Marioff is now able to offer commercial building owners a complete system to protect the entire property with environmentally sustainable water mist technology.”
The HI-FOG system uses high pressure to force pure, potable water through specially designed and patented sprinklers. The result is a mist of fine droplets with an increased surface area that absorbs heat through vaporization. The system controls and suppresses the fire by removing two of the main elements the fire needs to survive - heat and oxygen (reduced locally near the fire). The mist also rapidly cools the surrounding area, facilitating a safer escape for occupants, according to a company press release.
The company maintains that HI-FOG system require up to 90% less water than traditional sprinklers. The system can draw water from small, on-site water tanks and is an important fire protection solution in areas where water is expensive, in short supply or not readily available.
