ROAD TUNNEL WATER MIST FIRE PROTECTION

About Hydrocore

Founded in 2012, Hydrocore was established to bring innovative fire protection solutions to the market, specializing in high-pressure water mist technology. All our systems are designed and manufactured in our state-of-the-art factory in Hull, UK, ensuring the highest quality and reliability. Our product range has expanded to include both high-pressure and low-pressure water mist systems, as well as automatic and manual section valves with closed nozzles.

Hydrocore's commitment to excellence is reflected in our extensive certifications, including ISO 9001:2015, FM Approvals, CCS Approvals, and other independently respected body like UL, SGS, TUV performance-based tests.

Unveiling the risks: Why robust tunnel fire protection is essential

1

Fire Spread

Tunnel fires can reach 1000°C within minutes. Wind tunnel effects accelerate fire spread, while confined spaces make firefighting more difficult.

2

Casualties

Limited escape routes and rapid smoke buildup increase risks of injury and fatalities. Heavy traffic and smoke complicate evacuation.

3

Structural Damage

High heat weakens tunnel structures, increasing the risk of collapse and long-term damage.

Economic losses

Fires cause significant disruptions, resulting in economic losses and extended closures for repairs.

Hydrocore Water Mist Solutions

Rapid fire suppressior in confined spaces

Water mist systems quickly. control tunnel:fire by containing heat and limiting fire spread in confined spaces.

Smoke containment and scrubbing

Water mist traps smoke particles; improving: visibility and reducing smoke spread. Cleane air enhances evacuation safety and reduces inhalation risks.

Space-saving installation

Smaller tanks, pipes, and pumps save sp optimizing confined areas and:reducing: : infrastructure needs.

Efficient cooling to prevent re-ignition

50-micron droplets rapidly ábsorb heat, reducing tunnel temperatures:and preventi re-ignition. Prolonged dischargecools hot surfaces, ensuring safety post-fire.

One system for total protection

We validate our fire protection solutions using life-size tunnel experiments, ensuring their effectiveness with real-world data, including 20oMW tunnel fire tests. This example simulation shows how quickly fire spreads and smoke layers descend (smoke layer reaching the ground within 45s), leading to potential poisoning, structural damage, and a chain reaction of vehicle fires.
