The Tyr foam chamber is an air aspirating discharge device designed to deliver foam directly onto the surface of flammable or combustible liquid in a fixed tank protection system.
Tyr is available 2×3” up to 4”x8” body size and inlet flange (DIN or ANSI) and flow rates up to 2000 lpm. Tyr foam chambers are installed on the outside of flammable liquid storage tanks just below the roof joint.
Foam Chambers are used for fixed roof storage tank protection and generates a low expansion foam that are being applied to the surface of the flammable liquid. They are equipped with breacking glass seal that prevents flammable vapours from escaping out through the chamber.
The Tyr foam chamber is suitable for use with any foam proportioning systems such as bladder tanks, foam pump or inductor systems in applications such as:
- Petrochemical plants
- Tank farms
Tyr is recommended for use with following foam types:
- Protein, FP or FFFP 3% or 6%
- AFFF 1%, 3% or 6%
- AFFF ARC or FFFP ARC 3×3 or 3×6
- Multipurpose foam
Operation
Foam solution is supplied to a chamber from outside the hazard area, either from a fixed foam-storage and proportioning system or from a dry-pipe semi-fixed system that receives foam solution from a mobile foam apparatus.
When foam solution enters the chamber it is expanded and then discharged against a foam pourer mounted inside the storage tank.
The foam pourer gently apply the foam against the inside wall of the storage tank, reducing the fuel contamination of the foam.
