Water is the oldest but most effective fire suppression agent. Water still is protecting its effecience and importance on suppression due to its cooling and evaporation effect. However, Conventional suppression systems use big water drops on small suppression areas and water consumption is very high. The goods inside the affected area can be damaged because of the usage plenty of water.

Hybrid Fire Suppression System

AKRONEX hybrid system uses water as a natural agent and represent AKRONEX’s scope expertise of extinguishing. AKRONEX also supports risk assessment, system design, installation and operation and support. But the Hybrid Fire Protection System extinguishes open spaces and growing fires effectively and quickly at low hydraulic pressure. Unique two-phase flow technology separates the water and gas mixture into fine (atomized size) water droplets.

Furthermore, a Hybrid system can be applied for the protection of rooms and objects. The Hybrid system has become an effective extinguishing system by optimizing the physical properties of the water through the system. But In Hybrid system applications, pressurized water and gas mixture with 85-100 bar is pulverized with special nozzles and discharged at high speed.

SYSTEM WORKING PRINCIPLE

Hybrid system use a similar system with conventional fire extinguishing systems. But this time the water droplets (less than 10 microns) are 100 times smaller than 1 water drop. Hybrid system uses less water than the conventional system emits 50% more emissions and completely extinguishes. Unlike other systems, the AKRONEX inert suppression system utilizes both water and nitrogen at the best level. However, Water and nitrogen complement each other at perfect levels and extinguish the fire.

For small fires, nitrogen is the main fire-fighting agent. However, The Hybrid system reduces the oxygen in the area to the breathable level. The homogeneous mixture of water droplets and nitrogen gas is propelled with enough energy to overcome the drag effect.But that has limited the effectiveness of traditional water mist systems.

• Thanks to evaporation, it cools the temperature of the gases caused by the flame. But the surrounding fire and removes oxygen from the area,
• Attenuating radiant heat by the small droplets themselves,
• 85-200 bar pressurized water in hybrid system applications is pulverized with special nozzles and charged at high speed. The resulting water gas mixture occupies 1800 times more volume than the liquid phase of the water. Oxygen level in the area reduced to 12-15%,

The effectiveness of a hybrid system in fire suppression depends on its spray characteristics, which include the droplet size distribution, flux density and spray dynamics, with respect to the fire scenario, such as the shielding of the fuel, fire size and ventilation conditions.

Fire extinguishing system for small volumes

Extinguishing agents (water or powder selectively); especially extinguishing gases HFC-227 ea and HFC-125 are providing complete and effective suppression. These gases are odorless, colorless, without post-fire residue and vaporize completely.

The system is divided into two types: direct or indirect application. In the indirect application, the system is activated by heat-sensitive wire (tubing), which detects the fire and provides the discharge of gas into the panel through a pipe installed inside. In the case of direct application, the gas is released as soon as detects flame and suppresses the fire on the first zone of fire arising. No need to install pipeline.

The Clean Agent Fire Suppression Systems. Automatic gas fire extinguishing systems don’t harm people’s health, don’t influence the environment, have no post-fire residue or clean-up, and are electrically non-conductive. Due to their clean and safe nature, they are widely used in areas with valuable equipment. Over time, however, environmental concerns led to regulatory changes. Specifically, according to the Montreal Treaty (1994), Halon 1301 — which was sold in our country for many years — was replaced by alternative clean gas extinguishing systems. As a result of this shift, the filling and refilling of cylinders with gas HFC-227ea (known as FM200), which is widespread in Turkey, has remained in deficit for many years. This shortage continues to impact the availability and maintenance of such systems across the region.

HFC-227ea (FM200) IS AN ALTERNATIVE TO THE MOST WIDELY USED HALON
Discharge: 10 seconds
No post-fire residue or clean up
Is electrically non-conductive
No damage to protected equipment
ODP=0 (ozone depletion potential is zero)
Standards: ISO 14520, UNE 23571, and NFPA 2001

HOW DOES the AUTOMATIC CLEAN GAS FIRE EXTINGUISHING SYSTEM?

Detectors, mounted in the protected zones (room, suspended ceiling, and raised floor), detect fire and send a warning alarm to the control panel. As soon as the control panel receives a signal from zone 1, it gives a sound pre-alarm warning. If the situation escalates and a signal is received from zone 2, it triggers an audible and visual pre-alarm warning. Building upon this, when the control panel detects a fire-by-fire scenario, you can take certain actions or stop the process as needed. At this critical point, the ventilation equipment system will be turned off, the fire alarm will be triggered, the UPS will be shut down, and the extinguishing agent will be discharged into the protected zone.

In order to support this automated response, fire extinguishing gas is stored in special cylinders for storage. Afterward, the gas passes through pipelines and discharges into the protected zone through nozzles. Ultimately, the concentration of discharged gas will be enough to extinguish a fire within 10 seconds.
