May 24, 2023, Milwaukee, Wis. – Johnson Controls has launched the new NFF-331 3%x3% Non-Fluorinated Firefighting Foam Concentrate.
Designed as a flexible and efficient replacement for existing alcohol resistant aqueous film-forming foam (AR-AFFF) concentrates in conventional foam sprinkler systems, the NFF-331 concentrate provides fire suppression on a wide range of Class B, hydrocarbon, and polar solvent fuel fires.
NFF-331 foam concentrate has achieved UL 162-listed application rates like legacy AR-AFFFs with various upright and pendent sprinklers on hydrocarbon and polar solvent fuels. The low application rates can simplify system designs, facilitate ease of retrofit and minimize water requirements.
As an alcohol-resistant synthetic fluorine-free foam (AR-SFFF) concentrate, the NFF-331 foam has been UL-listed for suppression of hydrocarbon fuel fires and a broad range of flammable polar hazards, including isopropyl alcohol, ethanol, acetone and other common polar solvents and fuels. It is also EN 1568:2018-rated (Parts 3 and 4) on hydrocarbon and polar solvent fuels.
The foam is ideally used for protecting operations that handle flammable liquids, such as warehouses, fuel loading stations and processing facilities. NFF-331 concentrate is also compatible with most conventional foam sprinkler systems.
Since water consumption is directly related to application rates, foam sprinkler systems utilizing NFF-331 concentrate may require lower water flow compared to other non-fluorinated foams in the industry. This is especially advantageous for systems with restricted water supplies and benefits new installations since newer systems may be designed for efficiency and optimized resource consumption.
NFF-331 foam concentrate may be proportioned with most conventional, properly calibrated proportioning equipment and is ideal for both fixed and semi-fixed foam systems using sprinklers, nozzles, foam chambers and other standard discharge devices in a wide range of applications. The firefighting concentrate may also be used as an on-site response product and has been compatibility-tested with dry chemical agents in a twin-agent system.
