1. Concept -oxygen reduction principle

An ecological solution

8

By adding nitrogen-enriched air to the atmosphere the mixing ratio of oxygen versus nitrogen is changed and a fire cannot start

O.R.S (Oxygen Reduction System)N2 FIREFIGHTER® methodology

The N2 FIREFIGHTER® methodology prevents the development or spreading of open fires by adding nitrogen to the atmosphere.

PSA NIMOS technology

ISOLCELL provides three different technologies for nitrogen production

MEMBRANE ISOSEP technology ADOX® technology

11

PSA NIMOS (Pressure Swing Adsorption) technology

Adsorption process with carbon molecular sieveOperating pressure: approx. 6-10 bar

1. Compressor2. Water separator3. Air tank4. Electronic condensate discharge5. Pre filter6. Air dryer7. Fine filter8. Microfilter9. Activated carbon filter10.PSA Nitrogen generator11.Process tank12.Nitrogen buffer13.Dust filter14.Condensate separator

12

A flow of compressed air, dried and filtered, supplies the first tank, containing the molecular sieve. In the adsorption process the CMS will be saturated with oxygen and the nitrogen passes by.

While the first tank will be depressurised, the second tank will be supplied with air and the process starts again.

This cycle is continuously repeated, thus obtaining a constant and continuous supply

13

MEMBRANE technology

Filtering the nitrogen using a hollow fiber membraneOperating pressure: approx. 7,5 – 13 bar

ADOX® (Vacuum Pressure Swing Adsorption) technology

Adsorption process with carbon molecular sieveOperating pressure: approx. 1-2 bar

N2 FIREFIGHTER® VIRTUAL GRID methodology

Traditionally the oxygen is being measured in an area by using one or many point detectors, in some cases decentralized aspirating detectors are being used too. These detectors are logically put together in groups and each group represents an average value measured by the single detectors. From all group values together a new average is being calculated and displayed.

ISOLCELL's aim is to be as accurate as possible and to attain perfection.For that reason ISOLCELL has developed the Virtual Grid methodology. With the help of a

pipe system air is being aspirated from various heights within the protected area and even from the nucleus of the building. The aspirated air is being lead to a couple of zirconium sensors which comply with the European machine directive SIL EN 62061 / EN ISO 13849-1.

This method ensures that the air from each point of analysis is being sensored by the same detectors and the precise value of oxygen is displayed. A further advantage is the long lifetime of the zirconium sensors especially as electrochemical sensors tend to deteriorate quickly.

Variable pitch, virtual grid

21

Oxygen detection by using an existing or newly build aspirating smoke detection system, compliant with EN 54-20, EN 50104, EN 61508

For measuring the oxygen with the reliable virtual grid methodology the ASD pipework can be used

22

For smaller applications the zirconium oxygen sensor Oxyguard is recommended

Oxyguard generates the following messages:

Short circuit Oxygen level Fault message Revision messages

Point sensor detection system with OXYGUARD; compliant with EN 54-07, EN 50104, EN 61508

Advantages of reduced oxygen atmosphereby using green technology

elimination of fire risk, 24/7/365 active protection, self monitoring business continuity is granted no damage to protected goods or machinery reduced significantly damage caused by smoke no structural damages through classical extinguishing agents like water,

foam, gas etc. no process interrupting false alarms the protecting atmosphere is non toxic no pollution, no residues due to green technology no pressure release required safe to human, at most protection levels atmosphere remains breathable

5. Ignition threshold and consequences

34

ISOLCELL and many others conducted fire tests in order to determine the ignition thresholds of different materials under various conditions.In all cases existing rules and regulations, like e.g. VDS 3527:2007, PAS 95:2011, CEN and national standards have been the basis of these tests.

All these tests results have been filed in publicly available documents. When designing an Oxygen Reduction System for the purpose of fire prevention, these official ignition points are the basis for ISOLCELL to define the oxygen level in the area to be protected.

8. Health & Safety

40

ORS atmosphere can be compared to high altitude exposure(The ratio between Oxygen and Nitrogen = 20,95 vol.% to 78,09 vol.% at all altitudes)

41

Oxygen concentration comparable to ORS atmosphere

42

43

Nowadays high altitude training has become very popular by top athletes to increase durance and performance in general. Training at high altitude also decreases the recovery and rehabilitation period.

As high altitude training is not always possible to be performed outdoors, the hypoxic conditions are being simulated by the Oxygen Reduction method. Low oxygen tents or especially designed training rooms are required.
