15 15 | 34 Dräger Infrared vs. heat of reaction technology Catalytic bead sensorInfrared sensor Used inDräger Measuring principle Heat of reaction sensors are based on the oxidation of flammable gases on the surface of electrical heated catalytic elements, the pellistor. Due to the emerging heat of combustion the electrical resistance of the pellistor changes. The electrical homogenous compensator (the inactive spiral coil) is covered with a chemical inert layer and is used as a reference resistance to the pellistor. The resulting resistance change in the active part will be altered into a output signal. By means of infrared light in a specific wave length the C- H bond of Hydrocarbon molecules will oscillate, whereas the infrared light will lose energy (light will be absorbed by the gas). In principle, the gas detectors will measure how much the light sent from the infrared lamp will be absorbed during the multiple passing through the gas. Colour filter in front of each detector will let pass only a small frequency range of light. The measuring detector has been tuned to the specific absorption of the C-H stimulation. The reference detector will measure the general light intensity. By comparison of both measurements a reliable result will be shown, which is largely independent to aging processes.

21 Dräger X-zone 5000 Technology Update August 2012, Russell Warn

22 Portable Gas Detection Portfolio Application overview

23 23 | 34 The product Dräger X-zone 5000 Patented: Device Integrated in Amplifier State-of-the-art area monitoring – the Dräger X- zone in combination with the Dräger X-am 5000 or X-am 5600 gas detection instruments can be used for the measurement of one to six gases. The transportable, sturdy and waterproof unit extends mobile gas detection technology to a unique system with many flexible applications

24 24 | 34 Area Monitoring - the concept Advantages of an area monitoring safety concept Big savings by implementing an area monitoring safety concept! Example 1: Use of one area monitor instead of multiple personal gas monitors; Savings due to eased logistics and training efforts for contractors within industrial shutdowns => reduced costs Example 2: An area monitor is placed where the gas hazard is expected => more safety It can be used additionally to the personal air monitors handed out to all workers; Rerelease procedures e.g. after lunch breaks can be eased. => less costs

25 25 | 34 Dräger X-zone 5000 Really noisy innovative area monitoring – 360° Good sound! 108 dB at 1 m or 120 dB at 30 cm Sweeping alarm sound from 1500 to 2300 Hz, that cannot be missed even with different industrial background noises -360° visible green LED illuminated ring indicates: no potential gas hazard -360° visible red or red/green LED illuminated ring indicates: gas hazard in combination with a -360° audible evacuations alarm

26 26 | 34 Dräger X-zone 5000 Innovative area monitoring – 360° The 360° gas access on the top of the Dräger X-zone acts as a wind shield => highest safety 360° gas access

27 27 | 34 Dräger X-zone 5000 wireless fence line monitoring Up to 25 Dräger X-zone 5000 units automatically interconnect to form a wireless fenceline. This interconnection of the transportable measuring heads enables quick monitoring of large areas, e.g. pipelines or industrial tanks within the scope of industrial shutdowns. If a unit indicates a gas alarm (mother alarm – red) the device transmits the alarms to all other units that are part of the fenceline to a daughter alarm – green/red thus ensuring a simple evacuation alarm. Alternatively a wired or a combination of a wired/wireless fenceline can also be formed. Wireless Alarm transfer from one instrument to the next => quick setup of a wireless fenceline reduces efforts for the construction site safety preparation

28 28 | 34 Gas heavier than air: dense gas or cold Gases Gas lighter than air: light gas or hot gases Hydrogen Methane Ammonia Acetylene Nitrogen Oxygen Carbon dioxide Propane Chlorine Benzene Phosgene Gas Dispersion Where to place an area monitor? Place an area monitor, where the gas hazard is expected, but where do you expect it? Depending on the gas type to be detected use socket

29 29 | 34 Dräger X-zone 5000 wireless fence line monitoring Typical recommendation Comparable to fixed gas detectors – X-zones shall be placed, depending on expected gases, in a distance of <25 m to ensure a safe area monitoring system Technical capability X-zones would interconnect wireless at a distance of up to 100 m With the used frequency of 868 MHz (Europe) or 915 MHz (Australia, USA, Canada) a good connection also around the corner or with obstructions in- between the X-zones can be ensured even though the distance might be reduced

30 30 | 34 Dräger X-zone 5000 wireless fence line monitoring Easy Setup within a MESH Network X-zones are automatically interconnected – the connection LED shows green, if a neighbour instrument is found; it shows red with no neighbour ALL DEVICES SPEAK TO ALL OTHER X- ZONES IN MINIMUM ONE OTHER NEIGHBOUR NEEDS TO BE FOUND TO TAKE PART IN THE COMMUNICATION OF THE WHOLE GROUP => HIGHEST SAFETY TO KEEP THE CONNECTION WITHIN THE FENCELINE left instrument switched on connection LED red right instrument turned on connection LED turned green

31 31 | 34 Dräger X-zone 5000 Pumped Area Monitoring An integrated pump – available as an option – provides continuous monitoring of areas in pumped operation. Thus the system allows for continuous monitoring of difficult to access areas or confined spaces from a distance of up to 45 m. By using the diffusion cap the X-zone 5000 with pump is also useable in the diffusion mode.

32 32 | 34 In contrast to personal gas detection instruments area monitors remain in the Ex area also in the event of a gas alarm. Therefore it is more important that they are approved for Ex zone 0 – continuous operation in explosive atmospheres is ensured. Dräger X-zone 5000 Zone 0 ATEX: I M1 Ex ia I Ma (Mining) II 1G Ex ia IIC T3 Ga (Industry – Zone 0) IECEx: II 2G Ex d ia T4 Gb C US : Class I, Zone 0, AEx ia IIC T3 Ga Class I, Zone 1, AEx ia d IIC T4 Gb

33 33 | 34 Dräger X-zone 5000 Dräger Bumptest Station, for bumptests and calibrations of the gas detection devices Dräger X-am 5x00 Dräger E-Cal Station, for bumptests, calibrations, configurations, fleet management of the gas detection devices No daily Bumptest required! A bumptest is only necessary when placing the instrument on the site. With 5 days runtime this may be just one time a week! Alternatively use the attractive X-am 5000/5600 maintenance tools: However, the gas detection instruments can also be quickly removed from the Dräger X-zone 5000 to allow usage of the accessories of the small personal gas detectors, such as the Dräger Bumptest Station or the Dräger E-Cal station.
