Functional description:

The Process-Analytic-Cooler model GT5 is used for the safe cooling of process, sample and flue gases in gas analysis technology. The gas to be measured is reduced reliably to a pre-set temperature/dew point via an industrial heat exchanger that is 1200 mm long (spiral form with additional turbulator) made of stainless steel.

Overview of advantages:

  • Robust gas cooler in transmitter housing (IP 65) for industrial applications
  • Fail-safe pipe heat exchanger made of high-performance stainless steel (1.4571). Suitable for combustible gases
  • Service-friendly setup with quick replacement system
  • Fitted Water-Trap protection against condensate breakthrough
  • Ambient temperature up to +60°C possible (desert design)
  • Temperature remote monitoring via built-in temperature sensor (option)
  • Ideally suitable from electrochemical sensors/measuring heads to upper class analyzers

Suitable for the following applications:

  • Emission measurements with fossil fuels
  • Renewable energy (Hydrogen technology)
  • Biogas
  • Ambient air monitoring
  • Process measurement
  • Heat treatments
  • Cement, glass-, steel-, paper industries
  • Combustion engines

Not suitable for the following applications:

  • Official measurements such as TA-Luft and BImSchV measurements are only possible to a limited extent
  • Applications with more than one heat exchanger

Note: The technical data applies at +25°C ambient temperature. In the case of increasing ambient temperature a reduction in performance is to be expected.
Water-soluble components, such as e.g. sulphur dioxide (SO2) and nitrogen dioxide (NO2), can be influenced by condensation.
Water-Acid-Trap: (only included in classic sample gas cooler) Maximum water pressure (membrane) 1 bar, pore size diaphragm: < 0.1μm, housing volume: 200 ml, material polypropylene (stainless steel as option)


The Process-Analytic-Cooler is available in two versions:
As classic sample gas cooler or pre cooler for external components

Classic sample gas cooler

model GT5SEM (IP 20) and model GT565M (IP 65)

The classic sample gas cooler removes the condensate with an attached Water-Acid Trap. With the built-in membrane technology of the SUN-Control-Analytik, this offers additional protection against condensate breakthrough and dust deposits. After the Process-Analytic-Cooler model you have a dry and dust-free sample gas corresponding to dew point for your high quality gas analyser/gas sensor at your availability.
