FOAM CHAMBER
Heavy duty welded construction with choice of Carbon Steel
or Stainless Steel material Frangible Glass Vapor Seal
Controlled Air Flow proportional to liquid flow for optimum
foam quality and rupture of vapor seal in narrow pressure
tolerances for increased reliability Field replaceable orifice
plate fitted with Foam Chamber
Description
Foam Chamber is used in one of the most common application to protect vertical fixed roof (cone) liquid storage tanks, with or without
internal floating roof with the low expansion foam system. The application of foam is on the basis that the risk comprises the total surface
area of the fuel. The foam system design guidelines generally used are in accordance with NFPA-11, standard.
Foam chambers are defined by NFPA-11 as Type II discharge outlets for delivering the foam to the surface of a flammable liquid. The
Foam Chambers are widely used with the Inline Foam Inductor, Balance Pressure Foam Proportioning system, Bladder Tank Proportional
or Foam Tender.
