  • Reduction of flue gas moisture resulting in improved accuracy & sensor life

  • Rugged and designed for long life by using high quality acid resistant materials

  • Small, lightweight & efficient with sophisticated gas path 

  • Fast operation thanks to easy connection and start-up

You can rely on accurate measurement results, even when carrying out measurements on very humid flue gas. With the gas cooler, you can easily minimize measurement inaccuracies due to water vapour.

Easy and reliable external gas conditioning: use the gas cooler to ensure optimum preparation of very humid flue gas for measurements with the compatible measuring instrument (please order separately).

Water vapour is cooled in the gas cooler until it condenses. The resulting condensate remains in the gas cooler. The conditioning process minimizes leaching effects and prevents dilution of the measurement gas. This gives you more accurate measurement results when analyzing flue gas with the compatible measuring instrument.
