Foam Chamber
Model 95
Foam Subproportioner
Model 285
Series 95 foam chambers are designed to form and inject non-flammable, low expansion foam directly onto the liquid surface inside the storage tank; and thus be able to form a layer capable of extinguishing the fire by eliminating oxygen, they are generally installed on the sides of vertical atmospheric storage tanks (fixed and floating roof), above the maximum liquid level connected directly to the mixture supply line. water/foam.
Counter-pressure injection is intended to form a layer on the surface of the liquid, but coming from the bottom of the tank. In the event of a fire, if traditional foam chambers become damaged or fail, they can easily be replaced with subsurface injection.
