FIRE SPRINKLERS & SUPPRESSION

A serious fire could have devastating effects. It could claim not only the lives of people you know and work with but destroy your business and put you in a situation that’s hard to come back from.

You can implement best practice measures to avoid this happening at all. Ultra Fire has over 60 years of combined fire suppression knowledge and together we are confident we can put the best preventive measures in place, protecting you and your assets.

Gaseous Fire Suppression Systems

Gaseous Fire Suppression or Clean Agent fire suppression are terms used to describe gases used to extinguish fires. Typically gaseous agents work in one of two ways, the first is to inert the atmosphere reducing oxygen levels to a level that will no longer sustain combustion, the second is to react chemically with the fire absorbing heat and causing the chain reaction of combustion to break down.

Gaseous Fire Suppression systems are typically used to protect three-dimensional enclosures containing high-value assets that are vital for business continuity, and assets that cannot be protected by traditional sprinkler systems due to the potential for water damage. Typical examples of system applications include telecommunication facilities, clean rooms, data processing centres, and museums.

Compliant systems are subject to testing and an approval process that takes into account agent importation licenses, pressure vessel approvals, system performance, reliability, human safety, environmental impacts, etc. Gaseous Fire Suppression products supplied by Ultra Fire are environmentally friendly and cost-effective solutions and meet all regulatory authority requirements.

Where easy clean-up, minimal downtime, business continuity, and people safety are overriding factors, you need to consider clean agent gaseous suppression for your fire protection needs. We will help analyse your facility and operations to determine the most suitable fire suppression agent for your application and your business.

Conventional fire systems provide personal and structural protection. But when it comes to high-value assets and irreplaceable items, water can be just as damaging as any fire!

So why clean agent systems?

  1. Would your equipment be damaged or inoperable if impacted by water (fire sprinklers) or dry chemicals?
  2. Is your equipment and service difficult to replace?
  3. Do people occupy your facility?
  4. Can your facility tolerate business interruptions and downtime? Will your customers?

If the answer is “Yes” to any of the above, then a Gaseous Fire Suppression System is for you.

Kitchen Fire Suppression Systems

Contemporary commercial cooking environments requiring the use of healthier vegetable oils with lower auto-ignition temperatures coupled with highly insulated, slow-cooling appliances, have increased the difficulty of extinguishing fires in kitchens.

Water Mist and Wet Chemical fire suppression systems have been designed to protect commercial kitchens and exhaust hoods from the dangers of fire. A self-contained restaurant fire suppression system incorporates discharge nozzles over the appliance and along the entire length of the kitchen hood.

Heat detection devices located behind filters, run the entire length of the hood and activate automatically at a predetermined temperature. These systems are fully automatic and require no power to operate and protect the hood 24 hours a day.

Foam Fire Suppression

Foam Products encompass a wide range of products and equipment that includes firefighting foam concentrates, foam storage containers/tanks, foam monitors, foam system distribution and proportioning hardware. Firefighting foam or Foam Concentrate is used for fire suppression of flammable liquids.

Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, resulting in suppression of the combustion.

For a typical industrial foam system, the storage vessels (e.g. Bladder Tank or Atmospheric Tank) contain the foam concentrate and are connected into the distribution system ready for immediate use in the event of a fire. The associated distribution hardware and proportioning equipment are also connected into the piping system and control the amount of foam and how it is distributed to the hazard on fire.

As the world develops and technology changes, we constantly find ourselves looking at new applications and hazards. Foam extinguishing technology and products are also constantly evolving to meet these challenges.

For any particular application, there can be a number of possible solutions. Talking to fire engineers that specialise in foam products like us, should be your first stop in achieving the best result for your application.

Water Mist Fire Sprinkler Systems

Conventional fire sprinkler systems are designed primarily to control the fire and prevent building structural collapse, and pre-wet the surrounding combustibles to prevent fire spread.  This is achieved using copious quantities of water.

Water Mist suppression sprinkler systems are specifically designed to either suppress or extinguish a fire.  Water is an outstanding fire suppression agent due to its high heat capacity and latent heat of vaporisation. Critical to water mist efficacy is the nozzle which is specially designed to produce a specific range of droplet sizes and velocities.

The larger droplets from this fire sprinkler system have sufficient energy and momentum to penetrate the fire plume and cool the fuel.  The smaller droplets increase the overall enthalpy of the enclosure as well as being converted to steam at the flame front and entrained into the plume thereby displacing oxygen.  Extinguishment is achieved by a combination of these mechanisms.

Water Spray Deluge Fire Sprinkler Systems

High-Speed Deluge and extinguishing sprinkler systems detect and extinguish a spark or burning ember in under 300 milliseconds. Detecting a spark in a pneumatic material transport duct at speeds that often exceed 25 meters per second requires a very sensitive and very fast sensing device. High-speed infrared detectors that actually count sparks can quickly actuate a suppression sprinkler system that utilises water, CO2 or another extinguishing agent of choice to effectively protect the operating plant from fires and explosions. The detectors automatically and immediately reset themselves so that they stand ready to detect any possible subsequent sparks.
