Johnson Controls NFF-331 Non-Fluorinated Foam Concentrate offers outstanding performance for Class B fire protection sprinkler systems

  • NFF-331 3%x3% Non-Fluorinated Firefighting Foam Concentrate is tested and approved for use on a wide range of Class B, hydrocarbon and polar solvent and fuels
  • UL-listed for fixed and semi-fixed foam systems using sprinklers, nozzles, foam chambers and other standard discharge devices
  • Designed as an efficient and flexible alternative to AR-AFFF concentrates in foam sprinkler systems protecting operations with flammable liquid hazards

Johnson Controls, the global leader for smart, healthy and sustainable buildings, has launched the new NFF-331 3%x3% Non-Fluorinated Firefighting Foam Concentrate under its ANSUL®, CHEMGUARD® and SKUM® brands. 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 has been tested and demonstrated to provide excellent fire suppression on a wide range of Class B, hydrocarbon and polar solvent fuel fires.

“As the industry transitions toward new solutions to respond to current regulations, many customers are seeking non-fluorinated products to make the trade from legacy products as simple yet effective as possible,” said Beth Bjorlo, product management director at Johnson Controls. “Whether retrofitting an existing system or designing a new installation, our customers can have confidence that NFF-331 foam will deliver the optimum fire suppression performance with minimal water usage to protect their special hazard operations.”

NFF-331 foam concentrate has achieved UL 162-listed application rates similar to legacy AR-AFFFs with various upright and pendent sprinklers on hydrocarbon and polar solvent fuels. Listings include some of the lowest non-fluorinated foam application rates for polar solvents in the industry. In addition to quick and effective fire suppression, the low application rates can help 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 tested and 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.

Ideal for protecting operations that handle flammable liquids, such as warehouses, fuel loading stations and processing facilities, NFF-331 concentrate is 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 also 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. Specifiers seeking to retrofit existing systems should consult Johnson Controls technical service experts to review the system requirements for use with NFF-331 foam.
