Hydrocore High-Pressure Water Mist

A world leader in subway fire solutions

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.

The excessive fire loads by metro

vehicles, electric equipment and goods

people carry into underground stations in

combination with the high air flow along

platforms constitute a serious fire risk.

Dense passenger loads and limited

escape routes make safe evacuations

particularly challenging. High density

increases the risk of injury and stampede

during evacuations.

Subway fires produce extreme heat, are

difficult to extinguish and cause

extensive damages. Rescue efforts are

complicated by potential structural

integrity issues caused by high heat.

In case of fires, it is a challenge to safely

evacuate these areas due to the massive

heat development and the rapid smoke

spread as well as human behaviour in

congested areas.

Fire Risks in Mass Transport Facilities

Hydrocore Water Mist Solutions

Rapid fire suppression

in confined spaces

Water mist systems quickly control fires by

containing heat and limiting fire spread in

confined spaces.

Efficient cooling to

prevent re-ignition

50-micron droplets rapidly absorb heat,

reducing tunnel temperatures and preventing

re-ignition. Prolonged discharge cools hot

surfaces, ensuring safety post-fire.

Smoke containment

and scrubbing

Water mist traps smoke particles, improving

visibility and reducing smoke spread. Cleaner

air enhances evacuation safety and reduces

inhalation risks.

One system

for total protection

One system covers various fire types, from

vehicle to electrical fires, eliminating the need for

multiple suppression systems.

Space-saving

installation

Smaller tanks, pipes, and pumps save space,

optimizing confined areas and reducing

infrastructure needs.

Environmentally friendly

future proof

With no harmful chemicals and minimal water

use, the water mist system ensures

environmental safety. It meets global safety

standards .

Water mist pipelines and nozzles installed

beneath the handrails to spray vertically

upward to ensure evacuation safety

Escalators

Closed-style nozzles at the top of public

areas for quick fire response

The intersection of evacuation paths and

commercial areas should install

open-style nozzles to form water mist

curtain to prevent fire spread and allow

safe evacuation

Also outfitted with high-pressure water

mist guns for manual fire suppression

Platforms

A row of water mist nozzles installed

between the station screen doors and

the carriages, creating a high-pressure

water mist curtain

Outfitted with high-pressure water mist

spray guns to extinguish fires on the train

and platform

Track Area

2-3 rows of water mist nozzles installed

between two fire zones to prevent the

spread of fire

Reinforced with additional high-pressure

water mist guns for auxiliary fire

protection

Depot

Four layers of open nozzles arranged

around the main transformer for

comprehensive three-dimensional

protection of the substation

Substations

Closed or open nozzles installed at the

top of the electrical equipment room for

protection

Electrical Equipment Room

High pressure water mist technology was selected to be most favourable due to

▪ Fire test proof of fire fighting effect

▪ Best cooling abilities with smallest water amounts (lowest damage potential)

▪ Smoke reduction

▪ Lowest impact on electric equipment

▪ One fire fighting technology for all risk areas

▪ Easiest retrofit to existing metro stations

▪ Positive LCC balance

Water Mist Curtain Improve Evacuation at Track Area

Water Mist Curtain at Track Areas

The water mist curtain is suitable for both new subway lines and the renovation of old subway lines

When the train catches fire and it stops at the track area. Passengers escape to the platform

Effects of High Pressure Water Mist Curtain

The high pressure water mist curtain effectively blocks toxic smoke, prevents smoke spreading to the public area of

the platform

Eliminating the harm of high-temperature toxic gases to personnel, improving the evacuation environment for dense

crowds, and avoiding panic in the crowd

Water Mist Rings in Metro Tunnel for Evacuation

Situation - long metro tunnels

Water Mist, A smart way to evacuate, Defeat a powerful enemy by using a clever trick!

Hangzhou Metro tunnels and Tianjin Metro tunnels are over 600m long. Due to geological reasons, it is not possible to

construct escape routes between the up and down tunnels. How can passengers safely escape when the train stops in

the tunnel due to power outages during fire?

Effects of High Pressure Water Mist Curtain

Install mist rings on escape routes to prevent toxic smoke and heat from entering the safe passage in the event of a

fire, effectively improving the escape environment

After passing through the mist ring, passengers enter a relatively safe environment and continue to evacuate to the

nearby metro station
