Fire Extinguishment using Water

• The best way to remove heat is to dump water on the fire but,

depending on the type of fire, this is not always the best option.

• The most common agent is water; however, it cannot be used for

class B or C fires because it is conductive.

• Although only effective on only Class A fires, they have the

advantage of being inexpensive to operate and causing minimal

damage and cleanup.

• Water extinguishers or APW extinguishers (air-pressurized water)

are suitable for class A fires only.

• Water cannot be used on grease fires, electrical fires or class D fires

- the flames will spread and make the fire bigger!

• FIRE RE-IGNITION RISK IS HIGH

Working Principle of X Fire Pro

• Based on Fire Triangle, the combustion process requires three

factors: fuel, heat and oxygen.

• X-Fire extinguishing liquid affects the burning zone in three

ways namely:

• Producing extreme cooling effect

• Emitting of oxygen from fire volume

• Spreading a thin film type liquid layer preventing

further re-ignition

• X-Fire liquid has a shelf life of 10 years.

Working Principle of X-FirePro Extinguishing Liquid

• X-Fire Pro owes its extinguishing efficacy to the joint actuation of 4 main effects:

• Smothering - X-Fire Pro displaces the oxygen

thus producing a smothering effect.

• Cooling: X-Fire Pro which causes instant deep cooling

effect thereby reducing the heat radiation drastically. This

action minimizes the effect of 3rd degree burns.

• Attenuation: X-Fire Pro absorbs a great amount

of radiant heat, thus, avoiding re-ignition and fire re-lapse.

Automatic Fire Extinguisher - BONPET

Automatic fireextinguishing Mobile Extinguishing Dilution with water

How to use

The BONPET fire extinguisher ampoule's automatic activation

What happens if the fire breaks out in a closed area protected by BONPET?

Due to fire the temperature increases and as a result of it the extinguisher

liquid also gets warm and expand in the ampoule. When the temperature of

the liquid gets 85C°+/- 5C° it is converted into vapour and as a result of the

changing of the liquid state pressure is generated/created which breaks the

glass into pieces. The vapour spurts in the area starting endotherm

processes which take energy/power from the fire, thus dousing the fire

instantaneously

Automatic Fire Suppression Tubing System

Automatic

Fire

Suppression

Tubing

System

Fire Suppression Systems provide Cost-Effective, Stand-Alone,

Automatic Fire Suppression Systems for your Critical Equipment,

Electrical/Technical Systems and various types of enclosures.

The effectiveness of a genuine Firetrace System, happens by utilizing

the proprietary Firetrace Detection Tubing (a Linear Pneumatic Heat

Sensor), which detects a fire due to precise temperature sensitivity,

allowing our systems to react quickly and effectively.

This unique detection can be run through the smallest or most

complex enclosures to ensure detection is always close at hand.

Automatic Fire Suppression Tubing System

The heart of the system is the Linear Heat Sensitive pneumatic polymer tubing. It

is connected at one end to a Extinguishing Agent Container, which the rest runs

through the risk area, in a predetermined manner. When the flame touches the

tubing and it reaches a temperature of 67 Deg. C, the tubing bursts at it hottest

point (which is nearest to the most vulnerable part of the fire), thus forming a

nozzle .

The pneumatic mechanism then triggers the valve of the extinguisher & sprays

the agent out directly into the fire, thus dousing the fire quicker than any other

technique on the market.

This path breaking system, is entirely automatic, and once installed, requires no

human help. Thus making it the method of choice for “Localized environments”,

or areas which are cordoned off or have an enclosed area (such as panels,

servers..)

Automatic Fire Suppression Tubing System

DIRECT RELEASE SYSTEMS

Firetrace’s fire protection – direct release systems utilize the

tube as both the “detection device” and “suppressant delivery. As the fire

begins, the portion of the tube nearest the point where the most heat is

detected ruptures, forming an effective spray nozzle.

The pressure will then drop as the Firetrace tube releases the entire

contents of the cylinder through the distribution nozzle to effectively

suppress the fire. More than one Firetrace tube can be used enabling the

system to cover more area. Our fire suppression systems are critical for

safety and protecting your valuable equipments

Automatic Fire Suppression System operates on 2 different Techniques:

Direct & Indirect

INDIRECT RELEASE SYSTEMS

Once the tubing senses the fire, it ruptures –resulting in a drop of pressure causing the

Indirect Valve to activate

This diverts flow from the detection tube to the larger outlet ports

Then the fire suppression system kicks in – the Extinguishing Agent is discharged from the

cylinder through the diffuser nozzles, flooding the area in a proprietary mix of fire

extinguishing chemicals, effectively suppressing the fire quickly & thoroughly

This system is typically used in larger areas that require a high volume of Extinguishing

Agents, to effectively suppress the fire

Multiple diffuser nozzles may be added to meet the specific Application / requirements

Automatic Fire Suppression System operates on 2 different Techniques:

Direct & Indirect

Entirely automated , does not require any external power supply , thus it functions

perfectly in case an absence of electricity

Instant detection and instant suppression, without any Human involvement

The system is always ready to respond. Hence there is no downtime

Uses Novec 1230,DuPont FE-36 , NAF P IV , NAF S 125 , HCFC 123 and Co2

Flexible tubing allows protection of areas that were otherwise impossible to protect

Simple design. The system gets installed in a few hours, which means minimal labour

and downtime

Rugged design offers outdoor and indoor variants of the tube, and it can withstand

harsh conditions where other types of systems might be rendered inadequate.
