Stable gas temperature = reliable measurement result
In gas analysis, it is crucial that the sample gas retains its composition from the sampling point to the analyser. Temperature loss along the way leads to condensation of moisture and sulphur compounds, causing measurement errors, analyser failure and problems during audits. The heated sample lines from PSG (PerfectSampleGas) keep the sample gas at the right temperature along the entire transport route. Whether it concerns emission measurement (CEMS), process monitoring in the chemical industry or an ATEX environment, there is always a suitable PSG line for your application.
Practical result: 180 metres of PSG line were installed in EMI systems. Since commissioning: 0 failures.
Casestudy heated lines
Process safety
You want to know whether the flow stops or exceeds a limit value. The exact value matters less than the status. Typical for cooling water monitoring, lubricating oil monitoring and process protection.
Cost efficiency
Up to 25% lower energy consumption over the life cycle compared to classic PA12 lines (60 W/m vs 90 W/m).
Norm-compliant
Meets the requirements of ATEX Zone 1, IECEx and relevant emission standards. Ready for the strictest audits.
Flexible installation
Cut-to-length on site, up to 300 m heating circuit length, small bend radii possible, custom work on request.

How fast is the delivery time
PSG lines are available as standard within a few working days. Ready-made lengths possible on request. Contact us for your specific situation.
Are custom lengths and special versions possible?
Yes. PSG also supplies lines with small bend radii, special jacket materials, sensor integration or other inner tube materials. Tell us about your application and we will advise the right version.
Can the line be shortened on site?
Yes, all cut-to-length versions can be shortened on site without loss of function. This makes installation simple and flexible, even if the final length is only known on site.
Which ATEX zones are supported?
PSG offers lines for ATEX Zone 1 (II 2G), certified for explosion groups Ex IIB and Ex IIC, including IECEx. The ATEX certification applies to the entire assembly, including heating cable, connection and jacket, thanks to the patented Ex²/Ex³ technology.
Which temperature classes are available?
Depending on the model: self-regulating up to 120 °C (Process line), controlled up to 150 °C, 180 °C or 200 °C (Plus line). For high temperature stability up to 400 °C, special applications are available; feel free to ask us.
