HI-FOG is a fire protection system using water mist, this being the leading technology globally.
Water mist reduces downtime and damage to a minimum through proper control and rapid fire suppression using small amounts of water compared to other systems that require recharging or servicing after activation.
Marioff's HI-FOG is the most recommended system for the data center market, energy industries, automotive, pharmaceutical, food, financial sector and any place that protects high-value merchandise or documents that are irreplaceable.
Advantages of Water Mist Systems (Hi Fog)
- Environment and people friendly Quick installation
- Adaptability due to its smaller diameter pipes and space savings.
- System expansion for the future.
- High quality materials and long life helping with economic issues.
- Minimum damage in its activation and savings of reconstruction or remodeling resources.
- Performance based on approved laboratory testing.
- Variety of multiple uses in area applications.
Water mist as a fire fighting system is based on the evaporation of small water droplets converted into dew that turn into vapor upon contact with high temperature, thus generating a heat energy absorption reaction.
In this way, three methods of attacking the fire can be handled, where each of these methods can attack one of the elements of the fire triangle, that is, source of energy, fuel or oxygen.
Water mist systems, being an engineering-level technology with the best innovations, become one of the best solutions to meet the need for fire protection.
Immediate activation
HI-FOG sprinklers are activated when the ambient temperature reaches the determined threshold and the hot melt bulb breaks. The HI-FOG open mist head system can be activated as soon as the fire is detected, that is, when it is still in its initial phase, thus preventing it from spreading.
Zone cooling
HI-FOG displaces oxygen from the base of the fire, in addition to lowering the temperature in adjacent areas, thus preventing the fire from spreading or reigniting.
Operation
How does fire work? This needs 3 elements, which are Fuel, Heat Source and Oxygen. Water mist works by attacking one of these 3 elements through primary and secondary actions. Which are, cooling the gases, displacing oxygen, gases, vapors, humidifying the main heat source or fuel.Thus also canceling the radiation of energy in the form of heat and weakening the expansion energy in relation to the fuel.
Thanks to the fact that these systems work with high pressure discharges through holes and small diameters of pipes using a minimum of water, taking into consideration that water at this time or was it is vital to take care of it as a vital resource.
Taking into account that the principle of water discharge in tiny drops at high pressure and upon contact with a high temperature, turning into steam, generates an absorption of great heat energy.
Choice of protection based on Water Mist.
Taking into account the versatility of water mist, there is a wide range of applications with the principle of water mist for the protection of goods, properties and human lives.
In this way, the HI-FOG system seeks to cover needs depending on the areas and occupations, based on engineering that meets protection.
PREMIUM QUALITY
Wet Systems
Wet pipe systems are suitable for everyday fire protection as these systems activate immediately but discharge only a minimal amount of water mist, minimizing water damage. The advantages of wet pipe fire protection systems are quick response time and a quick return to operations as no major water damage repairs will be needed.
deluge systems
They exist in Local and Volume application, depending on the area occupied and defined through area analysis.
Local application systems are designed to protect specific objects, such as generators, diesel engines and transformers with large enclosures. These types of deluge systems only activate around the object in question, so they offer targeted protection for valuable technology.
Volume protection systems, also known as “full flood systems,” activate the entire water mist system at once. Therefore, volume protection deluge systems protect larger areas than spot application systems.
Dry systems
Cold temperature alone does not prevent fires, so low temperature areas must also be protected from fire. Because the pipes in the dry pipe fire protection system are not filled with water, but with compressed air, the pipes will not freeze even if the temperature drops below freezing. Therefore, they are a safe choice for difficult environments where frozen pipes can cause problems.
Preaction System
Preaction fire protection systems protect locations where accidental discharge of water must be prevented. These types of water-sensitive sites include, for example, data centers, museums, archives, and historical or cultural heritage. Preaction systems provide peace of mind knowing that they will not activate unless there is actually a fire. This minimizes the risk of water causing unnecessary damage to valuable items.
Why a water mist anti-ignition system?
Safe for people and the environment
HI-FOG It uses nebulized drinking water, making it a completely harmless extinguishing agent for people and the environment. To activate the system, it is not necessary to evacuate or isolate the space in which it will operate; in addition, you can also enter while the system is unloading, without this posing a danger to people's lives or affecting the efficiency of the system. extinguishing the fire.
Respectful of architecture
Thanks to the small diameter pipe, the compact pumping groups, the small water tanks and the discreet closed and open misting nozzles, HI-FOG is easy to install both in renovations and in new buildings, minimizing the structural impact and preserving the aesthetic integrity of the buildings.
Ideal for facilities that do not have supplies
The gas-operated HI-FOG Self-Contained Pumping Unit (GPU) can be provided as a standalone self-contained system requiring no connection to the mains, water supply or large tank.
Alternative
The most relevant components in a water mist system are an important element for the proper functioning of the system and effective fire control. These components are specialized to generate optimal protection.
Some of these components are:
- Sprinklers
- open nozzles
- Pumping equipment
- Water accumulators
- Valves
- Pipelines
- Water supplies
Approvals
The water mist systems that are managed have certifications that meet high standards of fire approvals, with globally recognized societies such as FM Global, VdS. These are based on and in collaboration with laboratory tests, trials, and teamwork with different communities of the fire protection system.
