FMNA, (formerly Fogmaker North America) announced the UL certification for its water mist Automatic Fire Suppression System (AFSS).

Underwriters Laboratories (UL), a global independent safety science company, performed more than 100 tests to measure system effectiveness under a variety of conditions including multiple fire sources and scenarios.

The certification, which included both system and component level testing, focused on lifecycle operation, environmental tests, product performance and overall durability.

“Underwriters Laboratories is the most prominent and trusted source for certification in the industry. We are honored by this certification and its recognition of the FMNA product performance and reliability,” said Ray Melleady, managing director, North America.

The patented, high pressure FMNA water mist Fire Suppression System attacks all three parts of the fire triangle: heat, fuel, oxygen. The vaporization of water into water mist displaces the oxygen, suppresses fires in seconds and rapidly cools the compartment. Tests show a 1321 ºF temperature reduction in less than 10 seconds. The FMNA AF³ solution blankets the fuel source. No other system is as effective in preventing reflash.

Unlike powder systems, the FMNA water mist system uses inert materials and is quick and easy to clean up. There is no powder mess. FMNA systems are U.S. Department of Transportation-compliant, approved by FIA and The International Motor Sport Association, and are compatible for use in hybrid propulsion systems.

USSC Group, a company focused on designing, engineering and manufacturing advanced safety and survivability solutions for the commercial and military transportation markets, has rebranded its fire suppression subsidiary, Fogmaker North America, as FMNA. There are more than 80,000 Fogmaker units installed worldwide.
