PSG AFFF Fire Suppression System: A Vital Safeguard for Highway Tunnels

In the critical infrastructure of modern transportation, highway tunnels present unique fire safety challenges. Confined spaces, high traffic volume, and potential fuel loads necessitate specialized, reliable, and rapid-response fire suppression systems. The PSG series Water-Forming Foam (AFFF) Fire Hydrant Box from Lijiang emerges as a premier solution engineered specifically for these demanding environments.

Manufactured in Fujian, China, under the reputable Lijiang brand, this system (Product Code: 02) represents a dedicated approach to tunnel safety. It is a non-imported, domestically produced unit, ensuring quality control and readily available supply for projects across various regions.

Core Features and Superior Construction

The device's official name, the Water-Forming Foam Fire Hydrant Box, precisely describes its function. Its primary component is a robust stainless steel (304 grade) foam liquid storage tank, available in capacities including 30L, 40L, 45L, and 50L (Model: PSG30/40/45/50). The use of 304 stainless steel guarantees exceptional corrosion resistance, structural integrity, and a long service life, even in the variable conditions of a tunnel.

This unit is pre-filled with Alcohol-Resistant Aqueous Film-Forming Foam (AFFF) concentrate. AFFF is highly effective on flammable liquid fires (Class B)—a significant risk in vehicle tunnels. It creates a fast-spreading film that cools the fuel surface and suppresses vapors, leading to rapid fire knockdown and preventing re-ignition.

Designed for High-Speed Fire Response

The Highway Fire Use designation is central to its design philosophy. The system integrates the foam storage tank within a compact, accessible fire hydrant box. This allows for a swift deployment protocol: in an emergency, responders connect the system to a water supply. The water pressure inducts the precise proportion of foam concentrate, generating the finished foam solution that is discharged through hoses and monitors onto the fire.

The ready-to-use nature of the system eliminates time-consuming mixing at the scene, a crucial advantage where every second counts. The specific 30L foam liquid storage model offers an optimal balance of potent firefighting agent volume and practical, space-efficient installation.
