Sinorix H₂O Jet

Automated extinguishing solution based on water mist technology

Sinorix H2O Jet is a solution using the natural agent water and reflects Siemens‘ extensive expertise in extinguishing. Besides the latest technology, it also comprises a comprehensive service portfolio – from risk assessment, system design, installation, and commissioning to maintenance.  Sinorix H2O Jet controls or even extinguishes open, fast-growing fires in a highly efficient way at low hydraulic pressure. Using a mixture of water and gas, its unique two-phase flow technology generates fine water droplets – for a maximum cooling effect. Moreover, the solution is harmless for both people and the environment.

About Sinorix H₂O Jet

Unique two-phase flow technology

The unique two-phase flow technology generates fine water droplets at low hydraulic pressure - for effective control of open fires as well as for accurate extinguishing in object protection.


  • Highly flexible for both object and volumetric protection

  • Low-pressure system reaching the same effectiveness as high-pressure system

  • Use of SinorixTM CDT (Constant Discharge Technology) for constant flooding

  • Unique two-phase flow technology uses a mixture of water and gas generating fine water droplets

  • Droplet size and amount of water is tailored to the specific risk of fire for an enormous cooling effect

  • Two different nozzles: one for object protection, the other for volumetric protection

  • Innovative nozzle for object protection patented by Siemens

  • Usage of simple galvanized pipes possible

  • Harmless for people and the environment as water is used as extinguishing agent

  • Objects stays well accessible thanks to high jet length

  • Low maintenance costs thanks to easy and cost-efficient refilling
