When powerful cooling is required, the TC-MIDI X2 sample gas cooler with -H2/-O2 heat exchanger is the ideal solution for reliable cooling of hydrogen (H2) and oxygen (O2) in extractive gas analysis. Green hydrogen produced by electrolysis using renewable energy sources is the key to a sustainable, emission-free future in the energy industry.
The safe, reliable cooling of the sample gas is decisive for gas analytics in the electrolyser (e.g. for LEL monitoring), as a higher moisture content is to be expected with some processes. The moisture in the process gas can damage the sensitive measuring cells in the analyser, so the gas temperature is kept below gas dew point at all times, thus causing the moisture to be emitted. The condensate is discharged via an automatic condensate drain.
As well as material-refining measures to prevent hydrogen- induced component damage, the heat exchangers for the H2 series are subjected to a leak test using helium. For the O2 version, special cleaning processes are used to remove particles, oils and fats from parts coming into contact with media. The contamination limits are based on the internationally used and applicable guideline EIGA Doc 33/18 “Cleaning of Equipment for Oxygen Service”.
Many applications require equipment which can be used in explosive areas. This is where the TC-MIDI X2 series provides solutions for Zone 2 or Class I, Division 2.
