I. Product Description
ZSTWC series medium-speed water spray nozzles, also known as impact nozzles, are mainly composed of frames, tips, splash discs (dust guards), etc. They are used to protect flammable liquid, gas, and solid hazard areas with flash points above 68℃.
II. Working Principle
The water flows through the nozzle, quickly atomizing into a mist spray to enhance fire extinguishing efficiency. During a fire, the nozzle continuously sprays water mist onto the exposed heat-absorbing surfaces of various nearby buildings, preventing heat absorption by these surfaces and the spread of the fire, thereby ensuring the safety of various structures.
III. Product Features
★Limit combustion speed, reduce fire damage, decrease explosion risk, promote steam dilution and dispersion.
★Utilizing water as the fire extinguishing agent offers excellent cost-effectiveness.
★In case of liquid fire extinguishing requirements, mix clean water foam with the mixer.
★ Can be effectively used in conjunction with other fire suppression systems.
