Foam Chamber ( ATCH1 ), also known as a Foam Injection Chamber ( ATCH1 ), is a device that injects the foam generated by a fire suppression system along the tank wall so it makes direct contact with the surface of the flammable liquid. Also known internationally as a Foam Chamber, this unit is specifically designed for floating-roof tanks; unlike a foam pourer, which discharges foam from the top of the tank, the foam chamber is mounted on the side of the tank body and gently feeds foam into the space between the floating roof and the tank wall.
Foam Chamber Technical Specifications
The body of Ader Tavan Nami’s foam chamber is made from ST12 steel sheet, 1.5 mm thick or heavier. This foam chamber is manufactured with 2″, 3″, and 4″ inlet sizes and 4″, 6″, and 8″ outlet sizes, and is fitted with a 2×2.5″ valve. Its standard working pressure is 4 bar, and the body is coated either electrostatically or with a three-layer (3LY) finish for resistance to corrosion and weather exposure. Final dimensions are determined according to each project’s drawings and work order.
Foam Chamber Applications in Industrial Projects
As one of the key components of a foam fire suppression setup, the foam chamber is used in high-risk projects such as floating-roof fuel storage tanks, refineries, and aircraft hangars. As foam is injected into the tank through the foam chamber, a stable layer forms over the surface of the liquid, blocking oxygen from reaching the flame and preventing the fire from spreading.
Why Choose Ader Tavan Nami’s Foam Chamber?
Every foam chamber built at Ader Tavan Nami is fully customized to match each project’s required inlet/outlet size, working pressure, and safety standard. Before production begins, our technical team provides a free consultation based on the tank type (fixed or floating roof) and the volume of flammable material involved, to help select the most suitable size and model.
