Fire Extinguishing Principles of Water Mist
	•	Sprays water mist using the motive power of the ignitionsource
	•	Small, high-density water mist with large total surfacearea that can quickly absorb large amounts of heat, decrease the temperature of the location of fire and maximize water utilization rate

Maximize the utilization of water
	•	The light-weight and high-density water mist particles are dependent on the thermal
		current of the ignition source
	•	It blocks the around influent ignition source to block circulation.
	•	It quickly absorbs large amounts of heat and decreases the temperature of the location of
		fire

Blocking of oxygen source
	•	The water mist particles can easily absorb heat and expands to about 1,760-times the original volume duringvaporization
	•	Forms a barrier outside the ignition source and blocks the oxygen source

Technical Cooperation
•		National project implemented by the Ministry of Science & Technology:
		Jointly developed with Chung-ang University
•		1st Project: Joint development of the low- and mid-pressure systems
•		2nd Project: Joint development of the high-pressure system
•		Korea Railroad Research Institute: Development of a water mist system for passenger
		railroad cars underway

	Water Mist Gun
	Simply hold the hand of pattern adjustment
	Easy to adjust the pattern of use
	Simple hydrants available
	Respond quickly to a fire shape
	Small and lightweight

Characteristics

	•	Direct spraying of high-pressure water mist on the flame using a portable pump.
	•	Maximizes cooling, oxygen block and fire extinguishing effects regardless of the
		type of fire.
	•	It can be easily managed and operated.
	•	It more easily Provides a cooling effect to approach the flame.
	•	It Allows remote fire extinguishing from more than 20m away.
	•	It Uses a small amount of water (12~25LPM) to facilitate water supply.
	•	It can use the water mist and regular hose as an alternative to fire hydrants.
	•	It can be applied to A, B, C fires and it is not harmful to human' body.
