Williams’ “PKW ™” is a highly specialized Purple-K that is one of the most effective dry chemicals used to extinguish flammable and / or combustible liquid pressurized fires.

When used in conjunction with Hydro-Chem ™ Technology effectively, it controls and extinguishes pressurized or three-dimensional “Class B” liquid fire. Its distinctive, deep purple color provides the fire fighter with the ability to stay ON-TARGET when designed for fire within the foam and / or water flow.

The result, when combined with Hydro-Chem ™ Technology, is the ability to achieve faster and more efficient “knockdown” and extinction.
