Foam Mixing & Application
There are many methods of adding Phos-Chek Class A foam concentrate to water from as basic as batch mixing to as sophisticated as automatically regulated proportioning systems. The different methods have pros and cons that should be considered in order to find the best system to meet your needs.
The mixed Phos-Chek Class A foam solution can then be applied by various discharge devices that affect the formation of bubbles. These different devices produce mixed foam solution varying from a wet or fluid foam suitable for soaking type applications (coal bunkers, peat bogs, dumps, etc.) to a drier shaving cream consistency for long-term foam blanket applications (exposure protection, pretreatment, etc.) The user should choose the most appropriate device to meet the objective of each application.
