PSG develops New Heated Sample Line: PSG Extruded Flex

No matter if Continues Emission Monitoring (CEM) or Process Analysis Technology (PAT): Extractive Analysis Technologies represent a strong growing market segment all over the World. At the same importance level of the analyser itself, the probe sampling system is responsible for an overall good result -so the primary probe sampling-, transportation and conditioning is a key component for a reliable overall result. One of the most underestimated elements in this process chain is the heated sample line. As other components like the analyser is installed in a protected environment, the analyser line is often installed outside and has to manage high temperature difference and other challenges like sun radiation. Depending on the distance between sampling point and analyser the length of the lines can be very long, in extreme cases up to 150 metres. For the installation and operation of the line the outside jacket is essential – a more flexible jacket reduces the product lifetime and has a higher risk to get destroyed during the installation – a more rigid jacket results into a higher bending radius which means more space (which is always very limited) is required. This dilemma was now solved due to the latest development of the Germany based company AGT-PSG, which managed to add another solution to the more than 2500 lines the company is already producing.

In the past the user had to choose between a flexible Ringwell Jacket (often produced of Polyamide with a very thin thickness) and extruded but rigid heated sample lines (made from PVC or TPU). So, in the past a tradeoff between high flexibility Ringwell Jackets with limited resistance against sun radiation or other environmental factors and Extruded Lines with a higher bending radius has to be decided. With its newest development this dilemma is solved: Due to a new production technology the PSG Extruded Flex line is produced with a PVC Jacket but due to the inside spiral the bending radius was reduced at around 50%. Even the cut to length technology is available which allows to shorten this line onside to the accurate length. With temperature ranges from freeze protection up to 200°C and various ATEX solutions the probe transport is solved in the company Slogan for PSG: Perfect Sample Gas.

AGT and PSG, whose products have been renowned for over 40 years as a hallmark for reliability and longevity, merged in 2016. This combined over 90 years of experience in gas sampling, gas conditioning, compressed air drying and compressed air distribution in one company.

AGT-PSG is now the only company to manufacture an entire range of products for continuous extractive gas analysis in-house for the global market. This enables their customers to obtain gas sampling probes, heated sample lines, sample gas coolers and sample gas conditioning systems from a single source.
