gas sampling probe and heated sample line is often dictated by plant layout and ATEX/IECEx requirements, conditioning and analyzer systems can frequently be housed within an analyzer shelter or container, providing a controlled and safe environment. When such an installation is not feasible, all sample conditioning components, including the Sample Gas Cooler or Dryer and the Sample Gas Pump, must comply with hazardous area classifi cations, alongside the analyzer itself. Certifi ed solutions, such as the PSG Process Cooler BCR ATEX, have been specifi cally designed and third-party approved for safe operation. These systems offer confi gurations with one, two, or even up to four gas paths, providing fl exibility and reliability in gas conditioning applications.

DIN EN IEC 60079-0 necessitate an assessment of the entire heated line, including electrostatic discharge risks. Safe operation can be ensured by employing authentic conductive jacket materials that are properly grounded through potential equalization.
Another key consideration is cut-to-length technology for heated sample lines. Since selecting the precise length is often tricky, lines are typically ordered longer than necessary. However, excessive length introduces multiple drawbacks, including:
Given that heated sample lines often represent the highest energy demand within the system, effective insulation is crucial for maintaining the required holding temperature while minimizing energy loss. Innovations such as the PSG Plus Extruded ATEX 180 heated cables have demonstrated energy savings of up to 25 % compared to conventional alternatives while providing the benefi ts of a robust outer jacket for industrial applications.
3. Gas Conditioning Systems
Gas conditioning constitutes the fi nal step before analysis after sample extraction via the Gas Sampling Probe and transportation through the Heated Sample Line. While the placement of the
In specifi c applications, an alternative to conventional compressor- or thermoelectric-based sample gas drying methods is using a Nafi on Dryer, such as those developed by PermaPure. Traditional drying techniques, including condensate coolers, adsorption dryers, and permeation dryers, often alter the composition of the sample gas by either precipitating certain components along with condensate, adsorbing them into water, or enabling their permeation. In contrast, Nafi on®
membrane-
based drying relies on a selective water transport mechanism, preserving the integrity of the sample gas composition. A thorough evaluation of relevant process parameters is required to assess the feasibility of Nafi on technology for a given application. The primary advantage of this technology in hazardous environments lies in its inherent safety: as it operates solely with instrument air and does not incorporate electrical components, the risks associated with ignition sources are effectively mitigated.
PermaPure Nafi on Dryer Conclusion
Optimizing gas sampling and conditioning in hazardous areas requires carefully selecting components that comply with stringent regulatory standards. Ensuring proper integration between the gas sampling probe, heated sample line, and gas conditioning system is essential for achieving reliable, accurate, and safe measurement results. Innovations in heating technologies, self-cleaning functionalities, and energy-effi cient designs continue to advance the fi eld, improving both system performance and sustainability.

Rapid, reliable and simple oxygen analysis for CEMS facilitates environmental compliance in the harshest industrial conditions
The need for precise and reliable Continuous Emission Monitoring Systems (CEMS) has never been greater as industries face ever-more-stringent environmental regulations. Advanced monitoring solutions are necessary to ensure effi ciency and accountability in emission control. SETNAG’s ATK/F-EUT and S24N-Oxybox’Air oxygen analysers have been engineered to meet the stringent demands of industrial settings such as large combustion plants, waste incinerators, steel plants, power plants, and steam generators.
SETNAG’s S24N-Oxybox’Air integrates seamlessly into CEMS frameworks, delivering fl exible oxygen measurement capabilities. It can analyse oxygen levels in wet and dry gases, ensuring adaptability to a wide range of process requirements. The wet gas measurement is performed through a connection at the heated hose outlet, while dry gas analysis is carried out after sample treatment. Meanwhile, SETNAG’s ATK/F-EUT provides direct oxygen measurement in wet gases adjacent to the process, eliminating the need for gas conditioning. This semi-in-situ technique ensures that the sensitive element remains protected from direct gas contact, thereby enhancing durability and measurement stability.
At the heart of these analysers is SETNAG’s innovative MicroPoas® Zirconia Sensor, which eradicates the need for a reference gas. This proprietary technology offers several advantages, including miniaturisation,
autonomy from external environmental factors, and high performance. Designed for operation in harsh environments, the sensor operates effi ciently under extreme temperatures and pressures while maintaining an extended lifespan. Its diffusion-based measurement principle also provides superior protection for the sensitive element, improving reliability and reducing maintenance requirements.
The S24N-Oxybox’Air offers ease of use, featuring rapid setup and minimal servicing demands, making it the perfect choice for industries that need continuous and long-term monitoring solutions. The AKT/F-EUT is also an invaluable component of CEMS, maintaining peak performance at temperatures up to 1300°C while ensuring free circulation of analysed gases. Its semi-in-situ measurement technique raises reliability while simplifying installation and maintenance operations, leading to lower cost of ownership.
SETNAG has also demonstrated expertise in developing oxygen measurement solutions tailored to waste incineration post-combustion processes, further solidifying its role in emissions control innovation. With a proven track record in power generation, district heating, industrial and domestic waste incineration, steam production, and steelworks, these analysers provide an essential toolset for industries striving to meet regulatory requirements and optimize combustion effi ciency.
As industries struggle with environmental compliance and process optimisation challenges, SETNAG’s ATK/F-EUT and S24N-Oxybox’Air analysers signifi cantly enhance CEMS technology. Their rugged design, ease of integration, and cutting-edge sensor technology make them indispensable for contemporary industrial applications, ensuring reliable, effi cient, and regulatory-compliant oxygen measurement in even the most demanding conditions.
