Enhance Tunnel Safety with PSG AFFF Fire Suppression Systems
In the demanding environment of high-speed tunnels, reliable and rapid fire suppression is non-negotiable. The PSG Aqueous Film Forming Foam (AFFF) Fire Suppression Device represents a critical advancement in safety technology. Engineered for swift response, this system is designed to control and extinguish flammable liquid fires efficiently, forming a protective film that seals the fuel surface and prevents re-ignition.
Manufactured with precision in Fujian, China, by the reputable brand Lijiang, this unit guarantees quality and durability. Its core component is a robust stainless steel construction, ensuring corrosion resistance and long-term reliability in harsh conditions. The system is a complete solution, encompassing a foam liquid storage tank and a foam hydrant box.

Available in models PSG30, PSG40, PSG45, and PSG50, the system offers flexibility to meet various tunnel specifications and hazard levels. The model designation often correlates with the foam concentrate storage capacity, such as the 30L foam liquid storage tank (304 stainless steel), providing a substantial reservoir for emergency operations.
The integration of the foam tank and hydrant box into a streamlined unit allows for quick deployment by emergency responders. Its primary application is for high-speed firefighting in tunnels, garages, and industrial settings where Class B fires (flammable liquids) are a prevalent risk. As a domestically produced system (non-imported), it offers excellent value and easier logistical support within its main sales regions.
Choosing the PSG AFFF system means investing in a proven, self-contained safety measure. It is a vital piece of infrastructure that can significantly mitigate risk, protect assets, and, most importantly, save lives in the critical moments following a fire outbreak. For operators of tunnels, transportation hubs, and industrial facilities, this system is an indispensable component of a comprehensive fire safety strategy.
Ensure your safety protocols are equipped for fast-action scenarios. The PSG AFFF Fire Suppression Device delivers performance, durability, and peace of mind.
