Foam Chambers - Foam Chambers are (UL Listed) type 2 discharge devices as defined by NFPA11 which are designed to lessen the submergence of the foam and deliver the foam directly onto the surface of flammable or combustible liquid. The foam chambers are installed on flammable liquid storage tanks just below the roof joint, flow rates are sized for the specific application. Foam solution is supplied to the chamber from outside the hazard area from a fixed foam storage and proportioning system or from a dry pipe semi-fixed system which receives foam solution from a mobile foam apparatus. Upon entering the chamber the foam solution is expanded and then discharged against a deflector mounted inside the storage tank. The deflector directs the foam against the inside wall of the storage tank, reducing the agitation of the fuel.

High Back Pressure Foam Makers - UL Listed High Back Pressure Foam Makers are designed for subsurface injection and are suitable for use with various types of foam solution systems, such as bladder tanks, balanced pressure, foam pump systems, ILBP's, and foam pumper trucks. Manufactured in carbon steel, but stainless steel or brass can be requested.

P/N CFM 70, 90, 250, 270, 1000 
Available in flow rates from 60 to 1200 GPM
 

• Designed to produce expanded foam that is introduced into cone roof storage tanks by sub-surface injection, and for use on hydrocarbon based fuels only, such as diesel, kerosene and gasoline. The foam maker is generally located outside the dike area that surrounds the storage tanks and is not recommend for use for tanks having a floating roof.
• Expanded foam solution is delivered to the burning fuel surface with minimum exposure to heat and flame
• Piping and equipment is located at the tank base and in areas not subject to damage from heat, flame, or explosion
