Abstract

A mobile modular foam fire suppression apparatus includes a movable platform. Supplies of foam concentrate and water are remote from the platform. A foam concentrate pump mounted on the platform pumps foam concentrate from a remote supply, such as a foam concentrate tank or tailer, to a water/foam proportioner on the platform. Water is provided under pressure from sources such as pumper trucks to a water inlet of the water/foam proportioner. The proportioner mixes the water and the foam concentrate to form a foam solution, which may then be applied to a fire with any of several foam solution discharge devices. Preferably, the apparatus also includes a foam concentrate return line which returns excess foam concentrate back to the remote supply of foam concentrate. This return line has a pressure regulator which regulates the pressure in a portion of the foam concentrate return line to a predetermined value. The apparatus provides an inexpensive way to manufacture and apply to fires large quantities of foam solution.
