About Sinorix H₂O Gas

sinorix-h2o-gas-visualSinorix H₂O Gas is a high-efficiency combination of nitrogen with a cooling water mist. To make your system as efficient as possible, we tailor it exactly to your specific applications and fire risks – from system design and piping networks to individual components. In an emergency, your system will release a precisely calculated and carefully balanced mixture of nitrogen and water mist over the required extinguishing zone. This ensures that the fire is extinguished quickly and safely. At the same time, Sinorix H₂O Gas also provides reliable protection of both people and the environment – thanks to its natural and nonhazardous extinguishing agents.

At the international Security Trade Fair Essen a panel of security and fire safety experts has recently rewarded Sinorix H₂O Gas with the Security Innovation Award 2008

System overview Sinorix H₂O Gas

During a fire, Sinorix™ H2O Gas floods an area simultaneously with both nitrogen and water mist for ideal protection from combustion, smoke, and heat damage. Both extinguishing agents are carried by the same piping network and are distributed by the same nozzles to the flooding zone. Nitrogen is used as the extinguishing agent and as the propellant for the water, modifying the dispersement and softening the initial burst of gas. Thanks to the water component, reignition is not possible.

Sinorix H₂O Gas minimizes secondary damage with its fine spraying technology, which requires only 30 - 80 liters of water for each 100 cubic meters of space. It generates ultrafine droplets with a diameter of 10 - 50 μm. The smaller the droplets are, the larger their relative surface area is, and the greater the cooling effect they have. As a result, exposed surfaces are coated with only a very thin layer of water. This is usually harmless, even on electrical equipment, because the water normally evaporates within a few minutes.

The water mist additionally removes toxic fumes from the air. This protects the health of people in the affected area and prevents smoke damage to property. Moreover, the area can be entered and utilized sooner because the removal of the toxic fumes restores visibility very quickly.


Agents overview Sinorix H₂O Gas


Nitrogen is chemically inert and its density is roughly equal to the density of air, so the extinguishing agent and the air in the room blend perfectly. Thus, the needed concentration for effective extinguishing can be maintained for a long period of time.

Water is chemically neutral. When sprayed, it quickly dissipates a lot of heat, cooling the materials below their combustion temperatures. The smaller the droplets are, the bigger the specific surface of water and the better the evaporation and cooling effects. This reduces damage and prevents heat-related ignition of flammable materials. As it evaporates, the water's volume expands 1640 times, displacing oxygen close to the fire.

Neither nitrogen nor water present any environmental or health hazards ─ nitrogen constitutes roughly 79% of the atmosphere. They do not harm the ozone layer or contribute to global warming, nor do they create any harmful reaction products when they mix during the extinguishing process. If the fire itself did not create any toxic fumes, you can easily air out the affected area using ventilation systems or opening windows.
