Explosive Tests

May 26, 2010 automatic detection and N2 Generator explosion suppression tests conducted with the US Army (TARDEC) and UL representatives in attendance at UTeC Labs in Kansas , USA .

Two x 6" long by 6" diameter N2 Generators.

We extinguish the explosive fire approximately two to three times faster than an equivalent armor vehicle halon or HFC explosion suppression system and N2 does not create toxic hydrogen fluoride decomposition gasses like our halon and HFC counterpart systems do.  

N2 fire systems create a greater margin of survivability to soldiers inside armor vehicles either during a false fire system discharge or while under actual military attack.

Automatic Detection and N2 Generator Explosive Suppression Tests
at UTeC LABS in Kansas

Two x 6" long by 6" diameter N2 Generators mounted in the opposite left and right corners of the 130 cubic foot lexan test booth. The left N2 Generator was activated 40 milliseconds after the explosive fire was detected and the second N2 Generator was activated 100 milliseconds after the first N2 Generator.

 

 

 

You see in this video:

A) N2 Generator to the top left hand corner of the 130 ft3 Lexan test booth which replicates the inside of an armour vehicle.

B) To the left hand side of the booth we have 100 psi supplied air to gasoline fuel mix spray nozzle which blows across a heat ignition sparker to ignite an explosive fire ball inside the test booth with the spray nozzle supply valve being left open for 2 full seconds and the sparker igniter left on for 3 full seconds.

C) The explosive fire is detected in approximately 2 milliseconds, a delay of 40 milliseconds was programmed into the N2 release control box and we extinguish the three explosive fires in approximately 55 to 173 milliseconds after activating the first 6" long N2 Generator.

D) You will notice our N2 Generators create a 100 % clean nitrogen wind turbulence down along the inside walls of the protected space using a military N2 diffuser, thus removing the flame from the fuel and extinguishing the explosive fire.

E) Our N2 Generators also inert the protected space down to approximately 15.7 % oxygen per volume, at a 2 psi pressure increase and an ambient noise level increase to approximately 138.8 decibels for 150 milliseconds inside the test booth.

Explosive Fire Test without a N2 Generator Extinguisher at UTeC LABS in Kansas

You see in this video:

The 100 psi supply air and fuel mix gasoline spray nozzle discharging into the Lexan test booth, against an ignition coil that ignites the explosive fire ball, the fuel spray nozzle is left open for a full three seconds to allow the explosive fire to propagate and then burn itself out.




Pac Sci Optic Flame Detectors can detect an explosive fire
in approximately 1 to 2 milliseconds upon occurrence.


 










N 2 Towers have arrived

The new N 2 Towers Inc. Inert Gas Generator Fire Suppression System (IGFSS) is set to change the way the industry looks at clean-agent fire suppression systems. Utilizing newly patented technology the N 2 Towers IGFSS is completely rechargeable on-site and requires no high-pressure cylinders, compressed gas liquids or discharge piping/nozzles. The system is also completely environmentally friendly.

There are two different solid car airbag propellant, inert gas generators utilized in the N 2 Towers IGFSS. The N 2 Generator produces 100% nitrogen and the Poseidon Generator produces an approximate 1/3 nitrogen and 2/3 water vapor inert gas mixture. By providing either a 100% dry nitrogen or water vapour and nitrogen fire extinguishing inert gas mixture, our clients can choose the inert gas which best suites their specific fire system needs. N 2 Towers IGFSS inert gasses displace oxygen inside a room to below 15% per volume while offering additional heat sink fire extinguishing capabilities through the application of the water vapor if required. The resulting inert gas discharge from a N 2 Towers IGFSS has zero capacity for ozone depletion and very low global warming potential. Our inert gasses do not break down into hydrogen fluoride gas decomposition by-products when exposed to an open flame, such as many existing halon alternative chemicals and gasses presently available through the worldwide fire systems industry.

The following illustrations depict various solutions for general asset protection. Examples include a single N 2 Tower with a 180 degree discharge diffuser and decorative panels for a computer room application, a double stacked N 2 Tower with 360 degree discharge diffusers for shipboard engine room applications, as well as a double stacked “360” N 2 Tower with decorative panels for a Museum and or Art Gallery applications.

FIRE Protection made easy

The Poseidon Generator inert gas mixture has extinguished heptane test fires in a 1000 ft 3 space in eight to sixteen seconds after activation of one N 2 Tower (each inert gas generator protects a 250 ft 3 space). The N 2 Generator is expected to extinguish these same heptane test fires in 10 to 30 seconds after discharge of one N 2 Tower. Four generators can be activated from within one N 2 Tower thus protecting up to 1000 ft 3 . Protecting any room from fire hazards with an N 2 Towers IGFSS is simple as dividing the cubic footage by 1000 to determine the number of N 2 Towers needed. 

Some N 2 Towers IGFSS applications will not require a tower assembly to protect specific spaces – thus single or multi-actuated generators would simply require a mounting bracket for protection of: aircraft, marine/military craft, and general asset protection.

* Submittal and approval by the US EPA SNAP List is required to supply end users with the N 2 Tower IGFSS technology as a halon alternative for unoccupied and normally occupied spaces.
