UL listing for RF3 now includes bladder tanks, proportioners, foam chambers, foam makers and fire sprinklers.

The UL Listing with multiple standard automatic sprinklers includes Reliable F-1 upright and pendent style (5.6 and 8.0 K-Factors), Reliable Model G upright and pendant style (5.6 and 8.0 K-Factors), and the Reliable upright G XLO (11.2 K-Factor).

Noteworthy of the expanded product certification for Re-Healing RF3 foam concentrate with these fire sprinklers is the minimum UL listed sprinkler pressure of 7.0 psi (0.5 bar) – the same minimum pressure used for aqueous film forming foam (AFFF) concentrates.

According to a Solberg spokesperson, sceptics in the foam industry doubted that fluorine-free foams would be capable of achieving a UL listing with standard sprinklers at equal system pressures to AFFF.

‘AFFF was introduced in the early 1960s, at a time when vacuum tubes, and black-and-white television was considered advanced technology and John F. Kennedy was President. This time period is considered the last innovation in firefighting foam.

‘Through the hard work and dedication of our employees around the world, Solberg has redefined the firefighting foam industry. No longer will customers have to settle for old technology, selecting between firefighting performance or environmental responsibility. Only Solberg offers both features to the customer,’ said Dennis Kennedy, Executive Vice President of Amerex Corporation, parent company of Solberg.

RF3 foam concentrate is also UL-listed with the Tyco B-1 and Star B-1 sprinkler in both upright and pendent styles, at the minimum sprinkler pressure of 30 psi (2.0 bar), the same system pressure as used with AFFF foam concentrates.

In addition to the product certifications issued for RF3, Solberg has also expanded UL listings for fire sprinklers with Arctic 3% AFFF and Arctic 3x3 ATC (hydrocarbon and polar solvent fuels). Arctic foam concentrates are 2015 compliant to the US EPA Stewardship Programme on C6 fluorine chemistry.

‘Solberg has achieved a true milestone in the history of the firefighting foam industry. Innovation in the foam industry is not replacing one set of long chain fluorinated surfactants with another fluorosurfactant.

‘True innovation is taking off your blinders, not seeing the problem exactly the same as everyone else, and solving the problem from a completely different direction. Only Solberg saw the real issues regarding existing foam chemistry and decided to take this industry in a completely different direction,’ commented Steve Hansen, General Manager of Solberg.
