Non-pressurized Ultra-Fine Dry Powder Fire Extinguishing Device (Wall-Mounted)
The device employs a new type of propellant (solid-to-gas conversion), which outperforms other similar products that rely on gas-based propellants. It features low noise, minimal recoil, and long duration of action. When multiple units are linked together, they will not cause secondary damage to protected objects or buildings. With its small nozzle and splash-disk design, this device fully leverages the highly efficient fire-extinguishing performance of ultra-fine dry powder extinguishing agents, making it an ideal next-generation automatic fire suppression product.

Detailed description
Overview
The device employs a novel drive agent (solid-to-gas conversion), which outperforms other similar products that use gas-driven agents. It features low noise, minimal recoil, and long duration of operation. When multiple units are linked together, they will not cause secondary damage to protected objects or buildings. With its small nozzle and splash-disk design, this device fully leverages the highly effective fire-extinguishing performance of ultra-fine dry powder extinguishing agents, making it an ideal next-generation automatic fire suppression product.
Working principle
When the activation signal (either automatic or manual) is triggered, the initiator ignites the gas-generating agent. Once activated, the gas-generating agent rapidly produces gas, causing the gas to expand swiftly within the enclosure and increasing the internal pressure. When the gas pressure reaches a certain threshold, the gas thoroughly mixes with the ultra-fine dry powder, thereby bursting the aluminum membrane at the nozzle. The ultra-fine dry powder extinguishing agent is then rapidly ejected into the protected area and quickly spreads outward in all directions, forming a fully submerged mist-like extinguishing state. Under the combined physical and chemical effects of the ultra-fine dry powder extinguishing agent, the flames are effectively extinguished.
