Non-pressurized Nitrogen gas storage technology 20 m3 / 706 ft3 available from 2022 in fire suppression systems
The generator is electrically initiated by an airbag squib. It needs 1 Amp current for a couple of milli seconds, then a booster starts the decomposition of the grain. The used chemical grain content will stay inside the generator and only the Nitrogen gas is released.
This gas storage technology is completely maintenance free. The fixed chemical grain is stable and cannot leak. It contains mainly Sodium Azide, binders and coolants.
Easy transportable and long shelf life
The generator has a shelf life of 10 years without any maintenance. The unused generators have transport classification ADR class 9 and are air-freight transportable as UN 3268 cat. 4. The used generator is exempt from ADR as Class 9 UN3363.
No ODP, GWP or Residue
Using Nitrogen as fire suppressant means No Ozone Depletion, No Global Warming Potential and No corrosive Residues to clean up. The used generator will be recycled in a controlled manner as chemical waste.
Nitrogen at ambient temperature
The chemical decomposition is an exothermic reaction and releases the gas at ambient temperature + 10°C. The generator will become 130°C/266°F after deployment and needs 4 hours to cool down. The Generator has passed several ATEX tests.
Low gas release pressure
The release pressure of the Nitrogen gas has been measured to a maximum of 5 bar. The pressure inside the generator can come up to 45 bar at an operating temperature of 65°C/149°F. The generator housing is IP67 before and after usage.
Low noise level
Due to the low pressure gas release, the noise level of the gas flow will remain well below 127dB. All systems can be installed with a silencer which lowers the sound level to <99dB
