Wet Systems

Pre-Action Sprinkler system

Fire suppression systems fall into three fundamental categories: wet pipe, dry pipe, and deluge. Pre-action fire sprinklers fall right in between all of these.

Pre-action pipes start out as dry pipes; they hold water back using an electronic “pre-action" valve. This system requires two events to happen before any sprinklers discharge:

1.     The pre-action valve will only activate when an independent fire detection system detects a fire. Upon alert, the pre-action valve releases, water flows in, and the system essentially becomes a wet pipe system.

2.     Now that water is on deck, one or more individual sprinkler heads need to release to engage and discharge water.

Pre-action systems offer several advantages. It’s not uncommon for sprinkler heads to be falsely triggered. Accidental activation often results in costly, irreversible property and water damage. The two-event discharge requirement adds an elevated level of protection from such inadvertent discharges. The use of pressurized air or nitrogen in the piping system allows for the easy detection of leaks.

Deluge Sprinkler Systems

Water spray deluge systems are typically used in hazardous environments where fires may spread very quickly or where valuable equipment surrounding the fire needs to be cooled.

These systems are designed for use in a variety of special hazard applications. Many types of nozzles may be required to provide a properly designed special hazard fire protection system.

When it comes to managing the complexities and dangers of industrial facilities, no other company has our depth of experience, knowledge, skills or technology. Water spray deluge systems have been an effective defence against fire. Extreme Fire Solutions takes this simple idea to a new level. At the heart of our systems are specialised spray nozzles, positioned at the correct location, to quickly bring fire under control and stop it spreading.

Turning a set of nozzles into an effective fire system

Small droplets deliver big fire protection

Water Mist is a versatile and highly efficient fire-fighting medium. What differentiates Water Mist from traditional water based systems is its reduced droplet size. When a droplet of water vaporises, it expands by some 1,600 times. Because heat absorption is a function of surface area and not volume, smaller droplets mean more surface area and therefore faster heat absorption.

Water Mist has the unique ability to deliver water as a fine atomised mist. This mist is quickly converted to steam that smothers the fire and prevents further oxygen from reaching it. At the same time, the evaporation creates a significant cooling effect of combustion gases and blocks the transfer of radiant heat. In this way, Water Mist combines the fire suppression properties of both conventional water-based deluge or sprinkler systems and gaseous fire suppression systems.

Bush Fire Drenches

A bush fire Sprinkler Drenches is a fire control system that protects window openings. It is installed horizontally at the same level of the top of the windows. Its water head releases water or foam spray and cools down the window when activated.

While sprinklers are installed and designed to protect the inside of a building, Bush fire Sprinkler drenches are made to protect the outside of a building from any damage caused from a on coming fire from a neighbouring bush lands.

A bush fire drenches system is composed of a water source, a pump unit, distribution piping, control fittings, and the water head that resembles that of a sprinkler.

Wet Pipe Sprinkler Systems

Automatic fire sprinkler systems (also known as a wet pipe systems are widely regarded as the most effective method of controlling fires caused by a broad range of hazards.

With a century of proven experience, Extreme Fire Solutions offers end-to-end sprinkler systems to protect your people, business and assets.

Sprinkler systems can automatically detect a fire, transmit an alarm and control the fire. This can be the difference between a minor accident and a major business shutdown.

Led by professional project managers, Extreme Fire Solutions engineers design, install and commission reliable, cost-effective sprinkler systems by carefully analysing your buildings and facilities in terms of occupancy, operation and fire risk.

Dry Pipe Sprinkler System

A dry pipe sprinkler system is one in which pipes are filled with pressurized air or nitrogen, rather than water. This air holds a remote valve, known as a dry pipe valve, in a closed position. Located in a heated space, the dry-pipe valve prevents water from entering the pipe until a fire causes one or more sprinklers to operate. Once this happens, the air escapes and the dry pipe valve releases. Water then enters the pipe, flowing through open sprinklers onto the fire.

Advantages of using dry pipe fire sprinkler systems include:

• Dry pipe sprinkler systems provide automatic protection in spaces where freezing is possible. Typical dry pipe installations include unheated warehouses and attics, outside exposed loading docks and within commercial freezers.

Many people view dry pipe sprinklers as advantageous for protection of collections and other water sensitive areas. This perceived benefit is due to a fear that a

Fire services use the hydrant for a continuous flow of water which is vital to firefighting operations. A fire truck carries only enough water to make an initial fire attack. In the first minutes of a fire emergency a continuous water supply from the water mains must be accessed through at a hydrant.

In every fire emergency, getting a hydrant to work is one of a firefighters’ priorities. Accessing a hydrant without delay ensures that firefighters who are already inside a burning building tasked with search and rescue or attacking the fire can continue for as long as required. Often firefighters find that hydrants are hidden or not maintained and cannot be used at a fire emergency. This is not only frustrating for firefighters but it can lead to serious consequences in delaying operations.

A much greater awareness of the importance of hydrants in the community is needed so people will ensure hydrants near them are useable.

Hydrants may be hidden or unuseable when;

• Grass or vegetation has grown over the hydrant cover.

• Dirt, earth or rubbish has been piled over a hydrant.

• Cars are parked on top of a hydrant.

• Gardens have been grown over a hydrant.

• Hydrants have been relocated due to building construction.

• Markers have worn out or been dislodged Insects have infested a hydrant.
