ASHLAND, Mass. Dec. 20, 2011 - Marioff Corporation, a leading developer of water mist fire protection technology and supplier of system solutions worldwide, announced that HI-FOG Water Mist Fire Protection has received Underwriters Laboratory (UL) listing for use in Ordinary Hazard Group 1 (OH1) applications.  The UL listing, combined with the existing Factory Mutual (FM) Light Hazard (LH) system approval, makes HI-FOG the only water mist system approved by both organizations to protect commercial buildings, such as data centers, museums, offices, hospitals, high rise buildings, and hotels. Marioff is a part of UTC Climate, Controls & Security Systems, a unit of United Technologies Corp. (NYSE: UTX).

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 efficiently 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.

Compared to traditional sprinklers, HI-FOG systems are easy to customize, and feature small, bendable stainless steel tubes that are more adaptable than those used in traditional sprinkler systems; this makes the installation easier, particularly in retrofits. HI-FOG is an environmentally sustainable solution requiring up to 90 percent less water than traditional sprinklers. Less water means less damage to buildings, property, equipment, and other items of high value. Cleanup is faster and easier than with traditional sprinklers, which minimizes costly business interruptions and allows organizations to recover more quickly.
