Recommended Applications

The 3% can be used with conventional foam equipment with fresh, sea or brackish water.

Self inducting foam nozzles and foam nozzles with In-line inductors are among the most common types of hardware for application.

In addition to its use in aspirating foam equipment, it can be dispensed effectively through non-aspirating equipment Including fog nozzles, water spray devices and standard sprinklers.

Is effective in sub surface injection systems for non-water-soluble hydrocarbons. Sub surface injection is safe and reliable for fixed protection of storage tanks.


GreenFire Wetting Agent does NOT have a positive spreading coefficient and is therefore NOT considered an AFFF type foam.

However, its ability to form a stable foam blanket covering a fuel surface allows it to be used effectively in many applications where AFFF foams have previously been the standard.

Positive fire suppression and vapor control.

Proportions Readily: Permits use in a wide range or proportioning equipment.

Solution Stability: Solutions of GreenFire Wetting Agent do not present “transit time” limitations through handlines or in fixed systems.
