CLASS B POLAR SOLVENTS (AR-AFFF)

Descripción

CLASS B POLAR SOLVENTS (AR-AFFF)

Class B Foam Agents are ideal for suppressing fires involving petroleum-based products, LNG, rubber, and flammable and combustible liquids; such as diesel fuel, crude oil gasoline and ethanol.

ANSULITE Alcohol-Resistant Aqueous Film-Forming Foam (AR-AFFF) Concentrates produce a foam that is effective on hydrocarbon fuels as well as fuels such as methanol, ethanol and acetone which have appreciable water solubility or miscibility. AR-AFFF exhibits the best cross-functional performance for flame knock-down, burnback resistance, extended vapor suppression, manufacturing and proportioning consistency, and the longest potential shelf life.

While early alcohol-resistant foams were based on mixtures of protein foams and chemicals called metal soaps, the most current alcohol-resistant concentrates are based on AFFF concentrates to which a water soluble polymer (polysaccharide) has been added. When these foam agents are applied to a water soluble fuel such as methyl alcohol, a polymeric membrane is formed between the foam and the water soluble fuel. When these foam agents are used on a conventional (water insoluble) hydrocarbon fuel, they function as an AFFF foam by forming an aqueous film at the fuel/air interface.

The foam concentrates are UL Listed and available in a 5 gal (19L) pail,  55 gal (208L) drum, 265 gal (1003L) tote, or call for available bulk delivery.

Agent options:

ANSULITE Alcohol-Resistant Aqueous Film-Forming Foam (AR-AFFF) is available as 1×1 AR-AFFF, 1×3 AR-AFFF, 3×3 Low Viscosity AR-AFFF, 3×6 AR-AFFF, ARC 3% or 6% AR-AFFF, and 3% or 6% freeze-protected AR-AFFF.

ANSULITE Alcohol-Resistant Aqueous Film-Forming Foam (AR-AFFF) Concentrates

These concentrates are formulated from special fluorochemical and hydrocarbon surfactants, high molecular weight polymers, and solvents. Intended for Class B fires, their excellent wetting characteristics make them useful in combating Class A fires as well. They are transported and stored as a concentrate to provide ease of use and considerable savings in weight and volume.

There are three fire extinguishing mechanisms in effect when using the concentrates on either a conventional Class B hydrocarbon fuel such as gasoline or diesel fuel, or a Class B polar solvent (water miscible fuel) such as methanol or acetone.

An aqueous film is formed in the case of a conventional hydrocarbon fuel, or a polymeric membrane in the case of a polar solvent fuel. This film or membrane forms a barrier to help prevent the release of fuel vapor.Regardless of the fuel type, a foam blanket is formed which excludes oxygen and from which drains the liquids that form the film or the polymeric membrane.The water content of the foam provides a cooling effect.

ANSULITE 1X1 AR-AFFF Concentrate

ANSULITE 1×1 Alcohol-Resistant Aqueous Film-Forming Foam (AR-AFFF) Concentrate is formulated for use in a 1% foam solution on all Class B fuels, hydrocarbon or polar solvent, wherever life safety and asset protection is essential. Typical applications include oil and gas facilities, chemical plants, refineries and tank farms, alternative fuel facilities, warehouses, municipal fire service, and many others.

When diluted with fresh, salt, or hard water, ANSULITE 1×1 AR-AFFF can be discharged through aspirating or non-aspirating branch pipes and nozzles, fixed foam making devices, and sprinklers to suppress Class A and B fuel fires.

UL-162 listed and EN 1568 approved

ANSULITE 1X3 F-601A AR-AFFF Concentrate/ANSULITE 3X6 F-600A AR-AFFF Concentrate

ANSULITE 1×3 F-601A AR-AFFF and ANSULITE 3X6 F-600A AR-AFFF Concentrates can be used on either conventional Class B fuels or polar solvent-type Class B fuels. Because of the low energy required to make foam, they can be used with both aspirating and non-aspirating discharge devices.

To provide even greater fire protection capability, both agents may be used with dry chemical extinguishing agents without regard to the order of application. However, with the velocity of the dry chemical discharge, care must be taken not to submerge the polymeric membrane below the fuel surface when using the twin agent method on polar solvent fuels.

ANSULITE 1×3 F-601A AR-AFFF is intended for use as a 1% proportioned solution on hydrocarbon fuels and as a 3% proportioned solution on polar solvent fuels in fresh, salt, or hard water. ANSULITE 3X6 F-600A AR-AFFF Concentrate is intended for use as a 3% proportioned solution on hydrocarbon fuels and as a 6% proportioned solution on polar solvent fuels in fresh, salt, or hard water. Water hardness should not exceed 500 ppm expressed as calcium and magnesium. They may also be used and stored as a pre-mixed solution in only fresh, potable water. They contain no PFOS.

Application 

ANSULITE 3×3 Low Viscosity AR-AFFF Concentrate

ANSULITE 3×3 Low-Viscosity AR-AFFF Concentrate can be used with both aspirating and non-aspirating discharge devices because of the low energy required to make foam. The foam concentrate has a dramatically reduced viscosity that enhances performance in all types of foam proportioning equipment including inline eductors, balanced pressure systems, and built-in systems aboard CFR vehicles. Additionally, the firefighting performance of the concentrate is superior to other 3% foam concentrates.

To provide even greater fire protection capability, it may be used with dry chemical extinguishing agents without regard to the order of application. However, with the velocity of the dry chemical discharge, care must be taken not to submerge the polymeric membrane below the fuel surface. It is intended for use as a 3% proportioned solution on both polar solvent and hydrocarbon fuels in fresh, salt or hard water. It may also be stored and used as a premixed solution in fresh water only.

ANSULITE 3×3 Low-Viscosity AR-AFFF Concentrate is ideally suited for situations involving flammable liquid spills where prolonged vapor suppression is desirable in advance of the spill cleanup.

ANSULITE ARC 3% or 6% AR-AFFF Concentrate

ANSULITE ARC 3% or 6% AR-AFFF Concentrate can be used on either conventional Class B fuels or the polar solvent type Class B fuels. Because of the low energy to make foam, it can be used with both aspirating and non-aspirating discharge devices.

To provide even greater fire protection capability, it can be used with dry chemical extinguishing agents without regard to the order of application to provide even greater fire protection capability. However, with the velocity of the dry chemical discharge, care must be taken not to submerge the polymeric membrane below the fuel surface.

ANSULITE ARC 3% or 6% AR-AFFF Concentrate is intended for use as a 3% or 6% proportioned solution (depending on the type of fuel) in fresh, salt or hard water. It may also be used and stored as a premixed solution in fresh or potable water for use with the ANSUL Model AR-33-D wheeled fire extinguisher.

ANSULITE ARC 3% or 6% Freeze-Protected AR-AFFF Concentrate

ANSULITE ARC 3% or 6% Freeze-Protected AR-AFFF Concentrate’s minimum use temperature is the lowest of all conventional AR-AFFF products on the market. This concentrate can be used on either conventional Class B fuels or the polar solvent type Class B fuels. Because of the low energy to make foam, it can be used with both aspirating and non-aspirating discharge devices.

To provide even greater fire protection capability, it can be used with dry chemical extinguishing agents without regard to the order of application. However, with the velocity of the dry chemical discharge, care must be taken not to submerge the polymeric membrane below the fuel surface.

ANSULITE ARC 3% or 6% Freeze-Protected AR-AFFF Concentrate is intended for use as a 3% or 6% proportioned solution (depending on the type of fuel) in fresh, salt, or hard water. The foam concentrate may be stored at temperatures to 0 °F (–18 °C) without freezing. If stored below the minimum use temperature, freezing may occur. If frozen, the concentrate can be thawed and remixed before use.
