Products Description
Overview
Foam chamber is a closed or semi-closed device mounted on the side of a fixed-roof or floating-roof tank. It introduces foam concentrate and water mixture (premix) into the tank in a controlled manner. The foam is expanded and directed into the tank to form a stable foam blanket on the liquid surface, suppressing vapors and extinguishing fires.
Floating roof tanks, typically external floating roof tanks (EFRTs), have a roof that floats on the surface of the stored liquid to reduce vapor space and minimize vapor emissions. Foam chambers are used especially for rim seal fire protection, which is where the fire risk is highest due to the gap between the tank shell and floating roof.

FAQ
Q: How does a foam chamber work?
The foam chamber receives foam solution from a foam proportioning system. The solution enters the chamber, passes through an internal foam maker (with air induction), and expands into foam. The foam then flows through a deflector or pourer onto the liquid surface or seal area.
Q: What are the components of a foam chamber?
Foam maker (foam inductor)
Air aspirator
Expansion chamber
Vapor seal (glass or frangible disc)
Foam deflector or pourer
Inlet flange (connected to the foam pipeline)
Q: What types of foam can be used with foam chambers?
Compatible foam types include:
AFFF (Aqueous Film Forming Foam)
AR-AFFF (Alcohol-Resistant AFFF)
FP (Fluoroprotein Foam)
FFFP (Film Forming Fluoroprotein Foam)
The foam type must match the fuel type and system design.
Q: What standards govern the design of foam chambers?
Foam chambers are typically designed in accordance with:
NFPA 11 (Standard for Low-, Medium-, and High-Expansion Foam)
UL 162 (where applicable)
EN 13565 (European standard)
API 2030 (for floating roof tanks)
Q: How is a foam chamber installed on a floating roof tank?
Foam chambers are mounted on the tank shell, just above the floating roof. The deflector is positioned to direct foam onto the seal area between the shell and floating roof.
