Product Description

Overview.

Non-toxic fire protection of valuables and buildings - without consequential damage from water and chemicals with IG-541 fire protection 

In the event of a fire, when IG-541 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 IG-541 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 decreasing cardiac distress and maintaining arterial blood oxygenation and mental performance in low oxygen levels.

Trade Names.

Inergen, Inertech IG541, I-Flow IG541, Proinert IG541

Chemical Composition.

IG-541 is a colourless, odourless, electrically non-conductive gas with a density approximately the same as that of air. It is an inert gas mixture consisting nominally of 52% Nitrogen, 40% Argon and 8% CO2.

Gas Specification.

The gas specification is usually confirmed with a certificate of conformity (COC) from the manufacturer. It's also important to ensure each specification is maintained during the 10-year testing and a new COC is provided confirming each requirement below by your supplier for the new re-filled or re-tested agent. 

The mixture specification for IG-541 is as follows: 

a) carbon dioxide percentage range 7.6% to 8.4%.
b) argon percentage range 37.2% to 42.8%.
c) nitrogen percentage range 48.8% to 55.2%.

Extinguishant IG-541 shall comply with the specification shown below:

IG-541 Quantity Calculation.

Typically, gaseous extinguishing systems are used for protecting electronic equipment in data rooms or similar, we have therefore prepared a quick calculation to help understand and estimate the quantity IG-55 agent required in your enclosure. The factor provided below is also based on a design temperature of 20°C and an altitude of 0, changes in either will have a small effect on the agent quantity

Design Concentration = 45.7% (Higher Hazard Class A) 

Flooding Factor = 0.8689

Volume of enclosure in M³ x Flooding Factor = Quantity required in KG 

[Example assuming room volume of 150m³]

150 x 0.8689 = 130.335kg 

Typical Cylinder Fill Weights, Sizes, Pressures & Quantity Calculator.

Inert gas cylinders come in a range of sizes however the below is reflective of the most common sizes and pressures and corresponding fill weights for reference.

Pressure	67 Litres	80 Litres	140 Litres
200 bar	20.17kg	24.1kg	42.1kg
300 bar	-	33.5kg	58.5kg

By using the quantity calculation above, and the maximum fill of each cylinder above, you can work out how many cylinders are typically required for your protected area.

FAQs.

Can people be exposed to IG-541 or Inergen?
Yes, part of the approval process includes testing for adverse effects in humans at recommended design concentrations. Each of today's clean agents is safe for humans.  While we recommend always exiting the hazard in the event of a fire, it is important that people not be harmed by the extinguishing system. Some manufacturers even offer live discharge testing in occupied rooms for demonstration purposes. 
How does IG-541 or Inergen work?
Systems working on a total flooding principle apply an extinguishing agent to a three-dimensional enclosed space to achieve a concentration of the agent (volume percent of the agent in air) adequate to extinguish the fire. These types of systems may be operated automatically by detection and related controls or manually by the operation of a system actuator
What is the cost per cubic metre for an IG-541 or Inergen system?
It's a common misconception that the cost is per metre cubed, but the cost for a fire suppression system is based on volume, in addition to many other factors.  There is not an equitable cost per cubic metre that can be universally applied to a suppression system application. 
IG-55 or IG-541?
Both clean agents have advantages over one another. IG-541 has the additional benefit of decreasing cardiac distress in the event of a discharge and usually requires slightly less cylinders however IG-55 is more widely available and easier to fill making it slightly cheaper.
