Advanced Fire Protection for Critical Infrastructure: The PSG AFFF Fire Suppression System

In the high-stakes environment of highway and tunnel safety, reliable and rapid fire suppression is non-negotiable. The PSG Water-Forming Foam Fire Extinguishing Device represents a pinnacle of design and functionality for these demanding applications. Manufactured by the reputable Lijiang brand in Fujian, China, this system is engineered to deliver superior performance where it matters most.

This integrated foam fire hydrant box is a complete solution, combining a durable stainless steel enclosure with an internally housed AFFF (Aqueous Film Forming Foam) concentrate storage tank. The use of high-grade 304 stainless steel ensures exceptional corrosion resistance and longevity, even in harsh or humid environments commonly found in transportation infrastructure.

Key Features and Technical Specifications

The system is available in multiple models—PSG30, PSG40, PSG45, and PSG50—catering to various protection area requirements. The highlighted model, with its 30-liter foam concentrate storage tank (304 stainless steel), offers a robust capacity for initial fire attack. Its design is specifically tailored for high-speed firefighting scenarios in tunnels, where containing a blaze in its incipient stage is critical to preventing catastrophic events.

The core technology utilizes water-forming foam (AFFF), which rapidly spreads across the surface of flammable liquids, creating a film that suppresses vapors and cools the fuel. This action provides a fast knock-down of flames, a vital characteristic for controlling fuel spills or vehicle fires in confined tunnel spaces.

Why Choose the Lijiang PSG System for Your Project?

As a domestically manufactured product with non-imported status, it offers significant advantages in supply chain stability and cost-effectiveness without compromising on quality. The product comes with a traceable货号 (Item Code: 02) and 订货号 (Ordering Code: 02), ensuring precise procurement. Furthermore, the availability of authorizable private branding presents an excellent opportunity for distributors and large project contractors to strengthen their own brand presence in the security and infrastructure markets.

While primarily distributed in specific regional markets, the engineering and compliance standards embodied in this system make it a compelling choice for serious highway消防 (highway fire protection) projects globally. Its integrated design as an arc fire hydrant box allows for streamlined installation and clear, immediate access for first responders.

Conclusion: Investing in Proven Safety

The Lijiang PSG Water-Forming Foam Fire Extinguishing Device is more than just a product; it's a critical safety investment. It combines robust construction (stainless steel material), effective firefighting technology (AFFF foam), and purpose-driven design (for high-speed tunnels) into a single, reliable unit. For engineers, safety managers, and procurement specialists responsible for infrastructure resilience, specifying this system means choosing a verified layer of protection designed to mitigate one of the most severe risks in modern transportation.
