of oxygen versus nitrogen is changed and a fire cannot start

12. 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

MEMBRANE technology
Filtering the nitrogen using a hollow fiber membrane
Operating pressure: approx. 7,5 – 13 bar

3. Project – System design criteria

19. 19
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.
Monitoring of Oxygen concentration

Variable pitch, virtual grid

21. 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. 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 atmosphere
by 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. 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.

40. 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. 41
Oxygen concentration comparable to ORS atmosphere

42. 42

43. 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.
