Application scenarios

1. Foam fire extinguishing system: protect Class B fire high-risk areas such as oil depots, chemical plants, and airport fuel depots.
2. Space-constrained scenarios: vertical design saves floor space (40% less space than horizontal).
3. Anti-cross contamination: The capsule physically isolates the foam liquid from water to avoid premix failure.

Working principle

1. Water injection and pressurization: Fire water is injected into the outer cavity of the capsule → squeezes the foam liquid in the capsule.
2. Quantitative delivery: The foam liquid is squeezed out to the proportion mixer (such as 3%/6% concentration) → mixed with water flow and sprayed.
3. Automatic switching: After the capsule is emptied, the water flow is directly output (the system seamlessly switches to pure water fire extinguishing).

Features

1. Zero residue design: Capsule shrinkage rate > 95%, foam liquid utilization rate is extremely high (residue < 1%).
2. Visual monitoring: liquid level gauge + pressure gauge dual indication (pressure drop alarm when the capsule ruptures).
3. Fast filling: reserve the foam liquid injection port, replenishment does not need to empty the system.

Working pressure

1. Design pressure: 1.0~1.6 MPa (in accordance with NFPA 11 standards), bursting pressure ≥ 3 times the working pressure.
2. Capsule pressure resistance: 0.3~1.2 MPa (low pressure start, high pressure seal anti-leakage).
