Back to FOAM FIRE SUPPRESSION SYSTEM

FOAM CHAMBER

FOAM CHAMBER a discharge device is designed to apply an expanded foam blanket over the surface of a flammable liquid fire as gently as possible to achieve extinguishment and/or vapor suppression. Foam chambers are suitable for the protection of fixed roof-mounted tanks and are to be used as low expansion Type II discharge devices (as defined by NFPA11). A deflector is located inside the tank shell to deflect the discharge against the shell that results in a relatively gentle foam application on the fuel surface.

Application

The foam system design guidelines generally used are in accordance with NFPA-11 standard. Foam Chambers discharge device of foam suppression system are widely used with the Balance Pressure Foam Proportioning System, Bladder Tank Proportioner or Foam Tender.

  • Heavy duty welded construction with choice of Carbon Steel or Stainless Steel material
  • Controlled Air Flow proportional to liquid flow for optimum foam quality and rupture of vapour seal in narrow pressure tolerances for increased reliability
  • Frangible Glass Vapour Seal
  • Field replaceable orifice plate fitted with Foam Chamber
