ARC 3x6 BU

Fomtec ARC 3x6 BU 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. It is compatible with all dry chemical powders.

Description

Fomtec ARC 3x6 BU is a multi-purpose film forming foam (3x6%).

The main advantage of Fomtec ARC 6% is the 6% induction ratio on ALL class B fires, also polar solvents.

The film forming characteristics of Fomtec ARC 3x6 BU means that it spreads rapidly across a fire. As a result, it is effective against hydrocarbon fires and with the addition of special polymers it is also effective against polar solvents

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 liquid surface.

When applied on polar solvents a polymeric membrane makes it possible for the foam blanket to extinguish effectively. This works also on foam destroying liquids such as MTBE.

Fomtec ARC 3x 6 BU should be used at 6% proportioned solution on ALL class B fires, also polar solvents, in fresh or seawater.

Application

Fomtec ARC 3x6 BU is intended for use on class B hydrocarbon fuel as well as on polar solvent i.e Isopropanol, Methanol etc and other foam destroy-ing product fires such as MTBE.  It can be used with both aspirating and non-aspirating discharge devices. It is compatible with all dry chemical powders.

Typical Performance

Fomtec ARC 3x6 BU has been designed to give the properties of

  • Aqueous film forming foam.
  • Alcohol resistant foam.

The fire performance of Fomtec ARC 3x6 BU has been tested according to EN 1568 parts 3 and 4.

 

Proportioning

Fomtec ARC 3x6 BU can easily be proportioned at the correct dilution using conventional equipment such as:

  1. Inline inductors.
  2. Balanced pressure, variable flow proportioning systems.
  3. Bladder tanks.
  4. Around the pump proportioning systems.
  5. Water turbine driven foam proportioners.
  6. Self inducting branch pipes and nozzles.

The equipment should be designed to the foam type.

Storage/Shelf Life

Stored in original unbroken packaging the product will have a shelf life of at least 15 years. The recommended storage temperature range of Fomtec ARC 3x6 BU ranges from -4°C to 55°C. Shelf life in excess of 10 years will be found in temperate climates. As with all foams, shelf life will be dependent on storage temperatures and conditions. If the product is frozen during storage or transport, thawing will render the product completely usable.

Synthetic foam concentrates should only be stored in stainless steel or plastic containers. Since electromagnetic corrosion can occur at joints between different metals when they are in contact with foam concentrate, only one type of metal should be used for pipelines, fittings, pumps, and tanks employed in the storage of foam concentrates.
