Foam Chamber
The EMACO Foam Chamber is a fixed low-expansion foam discharge chamber that applies expanded foam gently onto the liquid surface inside vertical fixed-roof storage tanks.
- Approvals: UL listed and FM approved
- 65 mm to 150 mm inlet sizes
- Options: Carbon-steel or stainless-steel
- Flow range: 150 to 3300 lpm
- Inlet-pressure range: 2.74 to 6.86 bar
Engineering overview
In the completed system, EMACO Foam Chamber acts as a Type II style tank discharge device that introduces foam through the shell of a fixed-roof flammable-liquid storage tank. Install at the approved elevation with a compatible foam maker or chamber assembly, deflector, seal, piping support and safe access for inspection. The chamber aspirates foam solution, includes a vapor-seal arrangement and guides finished foam down the inside tank wall to limit fuel agitation. EMACO lists carbon-steel and stainless-steel models with multiple inlet and outlet combinations. Select the model from tank diameter, required application rate, number of outlets, hydraulic pressure, fuel and concentrate listing. Do not approve a substitution on a product name alone. Check the exact model, listing, material, rating, connection and accessories against the submittal, then install and test the equipment to the project standard.
Technical Q&A
Which EMACO Foam Chamber configuration suits the design duty?
Start with the hydraulic duty and site constraints. Select the model from tank diameter, required application rate, number of outlets, hydraulic pressure, fuel and concentrate listing.
Where does the EMACO Foam Chamber connect in the fire-protection system?
Follow the approved layout. Install at the approved elevation with a compatible foam maker or chamber assembly, deflector, seal, piping support and safe access for inspection.
What must be checked before the EMACO Foam Chamber is ordered?
Compare the offer with the approved submittal before release. Confirm model, material, inlet and outlet sizes, listed flow range, operating pressure, vapor-seal material, flange and coating.
