In extractive analysis of process and flue gases, reliable and
constant reduction of sample gas humidity is essential. Bühler
Technologies offers a custom range of gas coolers based on
Peltier and compressor technology. Process-based cooling
temperature control guarantees maximum dew point
stability. This allows highest quality industrial gas analysis.
Bühler Technologies developed the extremely compact PC1
precooler to further increase the energy efficiency of the
above main coolers. It is used as a small passive cooling level
upstream from the main cooler. The PC1 very effectively uses
the ambient air supplied by the fan as a coolant. In moderate
ambient temperatures (up to 40 °C) it therefore allows the use
of small, cost-effective main coolers.
The intelligent gas path in the interchangeable precooling
heat exchanger further ensures very low washout of watersoluble gases (e.g. SO2/complies with EN 15267). Optional PC1
heat exchangers with built-in acid meter connection (H3PO4)
complete the concept.
