High-pressure Water Mist Fire Extingusishing Products
Summary of the high-pressure water mist system
A high-pressure water mist system
People-oriented is the core of the scientific concept of development, high-pressure water mist system has better drop smoke and the cooling effect created extremely favorable conditions for the escape of personnel, the drop high temperature degradation smoke, gas is the most effective and simple means.
High-pressure water mist fire suppression system is a very wide range of application of international an efficient water-saving, green fire-extinguishing system is in line with the "Montreal Agreement" alternative to halon fire generation product, alternative gas fire extinguishing water spray and water spray system.
Working pressure of 10 to 16 MPa, with automatic alarm system linkage, with automatic and manual two kinds of control mode.
Can achieve long-distance, high-rise building directly transported, stable performance, reliable operation, the system response time is short, easy maintenance, cost-effective.

Third, the characteristics of Advantages
Safety and environmental protection - with water as the extinguishing agent, the environment, the protection of objects, protected areas, there was no damage and pollution.
High fire - water mist immediately vaporized after a fire, rapid cooling, the cooling rate 100 times faster than the average sprinkler system. Pressure water mist penetrating, can solve the whole space and shelter, but also to prevent the resurgence of the fire.
Purification - smoke and exhaust gas purification, is conducive to the safe evacuation and fire fighting and rescue work.
Shielding radiant heat - the heat radiation have a good shielding effect, to prevent fire spread quickly to control the effect of fire.
Water loss is small - the water consumption is only 1% to avoid a large number of secondary disasters caused by the drainage of the water spray system.
Good electrical insulation - charged equipment fire fighting.
High reliability - the system installation is complete, the system periodically spray test, stainless steel, long life.
Flexible configuration - can be used as a full-space system to protect the entire space; topical, protect independent facility or a part of.
Easy to install - as opposed to the traditional fire extinguishing system, the pipe diameter is small, only 10 to 50 mm, the installation cost is reduced accordingly, saving a lot of space.
Easy maintenance - only water for extinguishing agent, atmospheric standby routine maintenance workload and greatly reduce the cost.
Fourth, the water mist standards-related content:
National standard "water mist fire suppression system technical specifications", "water mist system general technical conditions" to develop, will be the development of high-pressure water mist of great significance.
National standard "non-ferrous metals enterprises for fire protection design" participants group agreed that "water mist fire suppression system has the advantages of safety, environmental protection, high efficiency, water-saving, wide range of applications such as, to some extent, substitute gas, water spray, water spray extinguishing systems, state-of-the-art technology, well-equipped, compact configuration, reached the international advanced level. combined with the characteristics of non-ferrous metals industry: transformation and distribution system in the control room, information center, the cable channel (cable mezzanine), diesel, hydraulic system and heavy oil depots and other applications; serious place in the dust of the roadway, yard, to degradation dust, clean environmental objectives. "
Pointed out that a cable dissection, electro-hydraulic device (other than anti-fuel), hydrogen seal oil unit, feed pump tank (other than anti-fuel) turbine storage tank (the main plant within the national standard "of power plant and substation design code for fire protection The) mill lubricating oil tank, diesel generator room and fuel tanks, cable tunnels and fire pump room diesel driven fire pump can be used water mist.
