A more recently developed fire extinguisher type, the water mist fire extinguisher targets heat to combat fire. All fire extinguishers work on the basic principle of removing any of the three basic elements needed for combustion—oxygen, heat or fuel. A. Therefore, expert interpretation and further work is required. The fine spray from the unique misting nozzle provides safety from electrical shock, greatly enhances the cooling and soaking characteristics of the agent, and reduces scattering of burning materials. How water mist works Working Principles When water mist is used, it generates several other extinguishing effects that destroy the conditions necessary for fires to burn, and/or which can result in neutralizing the actual combustion. What is the working principle of water fire extinguisher? Fire Extinguisher is a portable fire fighting equipment which can be moved manually to the fire. A water mist extinguisher is fire protection equipment that uses fine water particles two douse fire. What are Water Mist Fire Extinguishers? WATER MIST is the ultimate extinguisher for Class A fires and for locations where a potential Class C (electrical) hazard exists. The water mist cools down the fire to avoid re-combustion and suffocates the oxygen, thus smothering it. Working principle: During a fire, the sprinkler continuously sprays water mist on the exposed heat absorbing surfaces of various buildings near the fire area to prevent the heat absorption of the exposed surfaces and the spread of fire to protect the safety of various buildings. A water mist fire extinguisher is multi-purpose fire appliance that can be used safely on a variety of fires, including class A, B, C, E and F.

Water Mist Extinguishers. WATER MIST FIRE EXTINGUISHER A water mist fire extinguisher is a specialized extinguisher that can be effective for use across all class A, B, C . The ANSUL® AQUASONIC™ Water-Atomizing Fire Suppression System is a revolution in Class B fire protection. In the past I have heard of fire extinguisher companies saving money by putting class BC powder in a class ABC extinguisher. How do Water Mist Extinguishers work? Inerting - As the water mist turns to steam it expands approximately 1700 times, forcing oxygen away from the flame front, thus denying it the oxygen necessary to support combustion. These tiny droplets have a surface area coverage many times higher than water. The other one is called a propellant and is a pressurized chemical that makes the fire-fighting substance come out when you press the extinguisher handle. Yes, de-ionised water mist fire extinguishers have passed the di-electrical conductivity test which marks them as safe for use on live electrical equipment up to 1,000V. Water Mist is the ONLY extinguisher in the world of its type to be able to extinguish ALL classes of fire using only water and NO ADDITIVES. Water Mist Extinguishers: These extinguishers are upgraded variants of the water extinguisher. This is due to 2 key factors that differentiate water mist fire extinguishers from traditional water or foam units: they are filled with de-ionised water which cannot carry electrical current, and the microscopic droplets . Call us @ (+65) 6759 4163 or email us at enquiry@lingjack.com to purchase a MightyMist and book your training session. Inside, a fire extinguisher is quite like a giant aerosol can, often with two different substances inside.One of them is a solid, liquid, or gas substance for fighting the fire. However, even with all the preventative measures taken, shipboard fires still occur. (The principle is simple: the smaller the particles of water, the further they spread and the faster they cool.) The particles are attracted by the fire and cool the fire and reduce oxygen content. The deionized water mist is released from the canister and directly sprayed over the fire from a safe distance. A water mist fire extinguisher is multi-purpose fire appliance that can be used safely on a variety of fires, including class A, B, C, E and F. Water mist fire extinguishers have been approved by LPCB, the Loss Prevention Certification Board and BSI, the British Standards Institution - third party certifications from independent laboratories who can . How does it work? The water mist fire extinguisher has proved to be more effective compared to the traditional water fire extinguishers. The water replenishment solenoid valve opens when the water tank is low and closes when the water level is high. Water mist type is an option when clean agent extinguishers might pose contamination hazards. Cooling. Today, types of fire extinguishers used for fires that enter into human life unexpectedly and cause both material and moral harm, and sometimes cause loss of life, have different characteristics.. . Making use of water in the form of fine particles . Kitchen Fire Extinguisher are manufactured under the guidance of our skilled professionals to maintain a standard quality. When the water were discharge from the nozzle, they are converted into micro droplets that create the water mist as they approach the fire. Working principle: During a fire, the sprinkler continuously sprays water mist on the exposed heat absorbing surfaces of various buildings near the fire area to prevent the heat absorption of the exposed surfaces and the spread of fire to protect the safety of various buildings. Water mist extinguishers are safe for discharge on all fire classifications bar Class D fires. The Cannon 6-litre water mist fire extinguisher is BS-EN3 Kitemark certified. The fine mist the system generates can extinguish fire or limit its growth at an early stage, depending on the asset being protected. Based on the triangle of fire, i.e., fuel, oxygen and heat, if any of the three elements is removed, the fire should in principle extinguish itself. Notes The actual size of water mist droplets can be much smaller than 0.4 mm. Water mist system being used to extinguish the fire Water mist system and its working principle: The water mist system is a fire protection system that converts water into steam to restrict, suppress, or extinguish the fire by using evaporation to cool down the flame and surrounding gases. Known for its high quality and utility, these are highly demanded by our clients spread worldwide. 30 May. The water particle diameter is about 50 to 200 μm. MightyMist technology work on the mechanism to displace oxygen and heat with micro droplets of water that scatters around the fire. Water mist systems extinguish fires using the following basic principles: Cooling - As the mist is converted into vapor it removes heat from the fire source. Hi-Fog is a high-pressure water mist system that will replace any other existing fire suppression systems such as automatic sprinkler system, FM 200, IG100, IG55, NOVEC1230 clean agent fire suppression system etc. It is The size can vary between 20 µm (0.02 mm) and 1000 µm (1 mm), depending on the system in question.
