EXPERTS IN WATER MIST SOLUTIONS

EXPERTS IN HIGH PRESSURE WATER MIST

Hydrocore Limited was established in the UK in 2012, to design and manufacture, world class environmentally friendly, high pressure water mist fire suppression systems.

There are many approved and fire tested Hydrocore systems protecting people and property at industrial and commercial locations across the world.

These include Industrial Plants, Airports, Metro Stations, Rail Terminals, Road Tunnels, Transformer Substations, Engine Test Cells and many other risk- based applications.

WHAT IS WATER MIST?

Water mist is a highly efficient fire suppression system which is defined by micro-droplets with the size Dv0.99<1,000μm. Having previously been used only at sea it has become apparent that water mist technology can have the same desired effect on land. Over the last decade, water mist has proven to be more effective than sprinklers for the majority of applications.

Micro droplets in Hydrocore's high-pressure water mist system quickly absorb the heat and instantaneously evaporate transforming from water to steam. The steam smothers the fire and prevents further oxygen from reaching it. At the same time, the evaporation creates a cooling effect.

The presence of the three elements: oxygen, heat energy and combustible material is essential for a fire to sustain and grow. The removal of just one of these elements helps suppress the fire.

Hydrocore's high pressure water mist system goes further and attacks two of the elements - oxygen and the heat energy - creating a highly effective fire suppression effect.

Quick & Effective Fire Suppression. Hydrocore High Pressure nozzles detect the fire and are automatically activated when the ambient temperatures rise beyond the set limit. Uniform cooling of the affected area suppresses the fire owing to the velocity and the angle of the water mist created by the nozzles. Also, the superior atomising effect offers reliable fire suppression and the cooling of the flammable material prevents re-ignition.

Low water usage. The efficiency of this process means it uses far less water than a traditional sprinkler system.

Minimal damage. Using small amount of pure water, Hydrocore high pressure water mist systems disperse finely atomised mist in the affected area. Atomised mist allows fast vaporisation limiting water damage.

Lower downtime and lower refill costs. Quick recovery and less downtime as against other suppression systems which need servicing or recharging after an activation. Only potable water is used which is readily available and at a low cost.

Ease of installation. Hydrocore high pressure water mist systems use a very small amount of water as compared to standard suppression systems and hence require smaller diameter pipes, which are easier to install and less intrusive.

Less space/weight. Water storage tanks for water mist systems are much smaller than those required for traditional sprinkler systems. This is where HPWM systems score highly as an existing building may not have enough space to accommodate a large water tank. Also, if the tank is to be installed anywhere but the basement, the floor may not be designed to carry as much weight.

Ease of maintenance. Use of water without any chemical additives and the use of stainless steel for high pressure piping makes the system corrosion resistant which enhances the equipment life and ensures low operation and maintenance costs.

Safe and environmentally friendly. Hydrocore high pressure water mist systems use only pure water as a suppression agent. Hence the system can be activated even when people are in the affected area and fire safety personnel can also enter the hazard zones when the system is in action. Also, unlike a gas suppression system, there is no risk of explosion in a water mist system.

HIGH PRESSURE WATER MIST

HYDROCORE High Pressure Water Mist Systems operate at more than 100bar pressure to atomise the water into a fine mist and to create enough velocity to drive out any fresh oxygen from reaching the seat of the fire. Operating at these pressures Hydrocore HPWM systems offer a volume coverage as against an area coverage offered by conventional sprinkler systems.

HYDROCORE PUMP UNITS

Compact and modular, our frame mounted pump units offer an output range of 100lpm to 700lpm at a minimum of 100bar pressure.

All pump units can be supplied with a stand-by pump and motor. Each pump unit is fitted with two jockey pumps (1 working + 1 stand-by) and a buffer tank. Pump units can be supplied with an optional star-delta configuration to reduce the electrical load on the system.

HIGH PRESSURE PUMPS

Oil free, water lubricated nine piston pumps have a reduced potential of cross contamination of water and lubricating oil. These pumps have a corrosion resistant stainless steel construction and are high efficiency low pulsation pumps which effects in substantial noise reduction during operation.

BOOSTER / FEEDER PUMP KITS

Booster pump units are supplied with a 10 micron filter set to feed filtered water into the high pressure pump unit. Each set is sized specific to the project.

SECTION VALVES

Section valves also called zone valves are either motorised (normally closed type for open nozzle systems) or manual (normally open type for closed nozzle systems). Section valves can be located near the hazard to be protected or near the pump station. They allow the flow of water to be directed to the zone of fire based on signals from the FPS and are also used to isolate zones during routine maintenance of the system. These come in various sizes and are chosen based on the water flow rate for the zone to be protected.

SYSTEM CONFIGURATION

NOZZLES

Nozzles are one of the most critical components in a firefighting system and the ability of a firefighting system to extinguish / suppress a fire is dependent on the nozzle performance.

Hence, all Hydrocore nozzles undergo stringent fire and component tests and only approved nozzles are considered for use in our projects. Nozzles are typically of 2 types: Open nozzles and Closed (automatic) nozzles and are selected based on the hazard to be protected.

The nozzle body is manufactured from SS304 while the micro nozzles are made from SS316. Each micro nozzle is fitted with a filter to avoid any contaminants from blocking the openings.

For ordinary/light hazard and residential type occupancies, water mist systems are designed and tested to achieve property protection and life safety by controlling fires and reducing their damaging effects.

In case of industrial applications requiring machinery protection / volume or object protection water mist systems are designed and tested for extinguishment.

Our eco-friendly systems use a very small amount of water and in the purest forms, without any additives. Nozzles are suitable to be fitted in new as well as old buildings as they complement the aesthetics of old, heritage buildings and at the same time their smart design makes them an easy fit in to modern constructions.

Today Hydrocore water mist systems are protecting iconic buildings like the Shanghai Tower, Shanghai Bank, a Rennie Mackintosh building in the centre of Glasgow to name a few.

INDUSTRIAL APPLICATIONS:

The industrial sector is characterized by considerable investment in heavy machinery which is expected to operate in an uninterrupted manner. Any downtime for capital intensive and critical equipment like turbines, transformers and machinery can lead to heavy losses and hence getting back to work quicker is very important after a water mist activation.

Hydrocore high pressure water mist systems are designed to fight fires, protecting people and property. Reliable and effective, our systems are designed to suppress the fire without any manual intervention. Hydrocore high pressure nozzles have been optimised to offer application specific flowrates, offering a fast response and quick fire suppression.

Hydrocore have FM approvals which comply with British Standards (BS 8489 Part 4 and Part 5):

Protection of Gas Turbines and Machinery in Enclosures (up to 260m³) – Hazards like internal combustion engines, oil pumps, generators, transformer vaults, gear boxes, drive shafts, lubrication skids, generators, etc.

Protection of Local Application – Hydrocore are one of the few companies globally to have these approvals! Water mist protection of local applications is considered a special protection system where the water is discharged directly or around the hazard to be protected.
