Today, fire prevention and control in areas such as “tall buildings, underground spaces, public places, old towns, transportation, and petrochemicals” is becoming increasingly prominent. CSAN Tianjin Sanan Technology Co., Ltd. specializes in the development and production of high-pressure water mist nozzles with its advanced fire-fighting, cooling, smoke-reducing mechanism and excellent performance to become the most effective means to solve many fire problems.

 CSAN high-pressure water mist nozzle not only has high-efficiency water-saving, safe and environmentally-friendly fire-fighting function, but also has special functions of reducing smoke, cooling and reducing poison. It can quickly isolate the fire source, effectively degrade and block the smoke and toxic gases at the fire site, and form an escape route, which is beneficial to evacuate and protect the life safety of firefighters.

 The high-pressure water mist nozzle has a double fire-extinguishing mechanism of high-efficiency cooling and rapid suffocation, forming a special state between liquid and gas. The water consumption is 1% of the traditional fire extinguishing means, and the efficiency is 200-300 times;

 Balanced surface cooling, efficient heat absorption;

 Suffocating fire, and only occurs around the fire source;

 Impact emulsification and dilution, resistance to heat radiation, washing of fumes and exhaust gases.

 When water (pressure is 10 MPa or more) is sprayed from a high-pressure water mist nozzle, a water mist having a particle diameter of 10 to 100 μm is formed, and the particle diameter of the high-pressure fine water mist is more than 10 μm, and rapidly vaporizes after the fire, and the volume is expandable by 1700- 5800 times, absorb a large amount of heat, so that the surface temperature of the combustion is rapidly reduced; at the same time, water vapor forms water vapor, and the combustion area is surrounded and covered as a whole, so that the combustion suffocates due to lack of oxygen.
