Inergen is a mixture of 52% Nitrogen, 40% Argon and 8% CO2. However, in the event of a fire, when Inergen is discharged, it mixes with the air present in the room to create a mixture that comprises of 67.3% Nitrogen, 12.5% Oxygen, 17% Argon and 3.2% Carbon Dioxide.
This discharge mixture makes Inergen singularly unique. No other inert gas has the unique ability to rapidly extinguish a fire yet at the same time provide a safe environment for any person within the occupied area by actually decreasing cardiac distress and maintaining arterial blood oxygenation and mental performance in low oxygen levels.
Equally important, unlike some chemical gaseous fire suppression agents, Inergen does not, and could never create a reaction with a fire to create extremely harmful toxic or corrosive by-products.
Cost studies have shown that inergen is cost competitive when compared with the most popular chemical agents on typical systems. inergen does not take up premium floor space as the cylinders can be placed remotely from the protected risk.
inergen inert gas can be stored remotely, up to 100 metres from the protected risk. This means that a single bank of cylinders can protect a large number of “Multiple Areas” far more cost effectively when compared with the most popular chemical agents on typical systems.
Inergen inert gas is closer to natural air than any other gaseous fire suppression system, and has the propensity to remain within the protected enclosure rather than leak out. Therefore, the importance of room integrity to prevent agent leakage is not as vital as it is for chemical agents. This feature provides inergen with unique, superior holding times without extensive and costly room sealing or dedicated extract ducting. inergen can also protect a number of different areas from one central cylinder storage area.
