Foam chamber
Description
Chamber is designed to introduce expanded foam directly onto the surface of a flammable or
combustible liquid for fire extinguishment and/or vapor suppression. Foam chambers deliver low
expansion foam directly onto the fuel surface with a minimum of foam submergence and fuel
agitation. Minimizing submergence and agitation, increases the effectiveness of the foam blanket,
resulting in more efficient operation, and superior extinguishing capabilities. Foam chambers
have the added advantage of directing all their flow directly onto the product surface regardless of
weather conditions, for the most effective utilization of foam resources. Foam chambers have a
long history of timely and safe control of numerous incidents.
Foam chambers are compatible with all types of foam concentrate; protein, fluoroprotein, AFFF,
and AR-AFFF. They are generally installed on the side wall of vertical storage tanks above the
maximum product level. Piping coupled to the unit can be linked to a fixed foam proportioning
system, or terminated a safe distance from the tank, where foam solution can be delivered via
mobile fire apparatus or portable foam proportioning equipment.
Features
• Four Sizes to suit wide range of flow rates
• Suitable for use with all available foam concenrates.
• Operates at 40~90 PSI minimum
Operation
Foam Chambers produce foam by suctioning air into foam solution stream. Foam solution can be
delivered to foam chamber in a variety of ways as previously noted. The inlet of the foam chamber
is fitted with a factory installed high efficiency venturi jet which is designed to draw air into foam
solution stream. The seal (rupture disc) was made by fragile glass. When foam solution stream
was delivered into foam chamber, the glass will rupture and foam get to chamber and overflow
from outlet.
Air wss drawn into the foam maker through a series of reticular holes located around the integral
foam maker. To prevent obstruction, the air inlet holes are protected by a stainless steel screen
selected with a perforation size designed to exclude most known nesting birds and insects. The
open area of the screen is designed to be not less than the total area of the foam maker air inlet
holes.
The aerated foam solution then passes through a series of precisely designed mechanical
agitation devices which maximize foam expansion, and enhance drainage time. The expanded
foam then passes into the foam chamber body which is designed to further enhance expansion,
and reduce the velocity of the foam stream prior to discharge onto the product surface.
The foam chamber is fitted with a frangible vapor seal located at inlet to discharge pipe connected
to the storage tank. The vapor seal prevents the escape of product vapors to atmosphere and/or
foam system piping. The exclusive location of the vapor seal in the discharge piping, also prevents
the escape of product into the foam chamber in the event of an overfill situation.
The flow of expanded foam ruptures the vapor seal at a predetermined pressure, allowing the
foam to enter the tank.
As the foam exits the foam chamber, it impacts the deflector which is designed to direct the flow
against the wall of the tank to reduce the amount of foam submergence into the product, as well
as dispersing it to each side for more complete coverage.
