AFFF ARC 3×3 NV Supplied by Dafo Fomtec
Fomtec AFFF ARC 3×3 NV firefighting foam is a high efficiency multi purpose film forming foam concentrate.
Fomtec AFFF ARC 3×3 NV is a Newtonian liquid based specially selected hydrocarbon / fluorocarbon surfactants and does not contain any polymer that makes general AR type foam concentrates viscous. Its high fluidity makes the induction easier and accurate through both portable and fixed inline proportioners even at low temperatures.
The advantage of Fomtec AFFF ARC 3×3 NV is the 3% induction ratio on all class B fires including polar solvents in fresh or sea water. The low surface tension of the water foam concentrate solution enables the aqueous film, although heavier than the burning liquid, to float on top of the hydrocarbon fuel surface. The specially selected fluorocarbon surfactants ’seal’ the bubbles against attack from polar solvents and also provide a highly effective floating foam layer on top of the polar solvents.
Fire Performance & Foaming
Fomtec AFFF ARC 3×3 NV has been designed to give the best properties of:
Aqueous film forming foam
Alcohol resistant foam
The fire performance of this product has been measured and documented according to “International Approvals” stated in this document. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Average expansion 9:1, average ¼ drainage time 03:30 minutes using UNI 86 test nozzle.
Application
Fomtec ARC 3×3 NV is intended for use on class B hydrocarbon fuel as well as on polar solvent i.e Isopropanol, Methanol etc and other foam destroying product fires such as MTBE. It can be used with both aspirating and non-aspirating discharge devices.
Typical applications are bulk storage tank protection, process areas, power stations, marine terminals, municipal fire departments, offshore platforms etc. It is compatible with all dry chemical powders.
The advantage of Fomtec AFFF ARC 3X3 is the 3% induction ratio on ALL class B fires including polar solvents in fresh or sea water.
