Device for cooling the gas in order to separate the water vapour it contains.
Before a gas analysis, the sample gas usually has to be prepared. In most cases, this requires cooling of the gas in order to separate the water vapour it contains. Target substances of the analysis must be preserved in any case, which requires special measures for water-soluble gas components (e.g. SO2).
The core of the measuring gas drying in the GO-PKK cooling system is a gas cooler in which the gas is dried to a dew point of 5 °C in a cyclone heat exchanger.
The patented heat exchanger’s special design (analogous to cyclone particle separators) enables the gas to be cooled abruptly, after which the sample gas is immediately separated from the condensate and no longer has any contact with it in the further gas path.
This effectively reduces leaching losses. In addition to the cooler, the cooling system already contains a pump for condensate drainage and a collecting vessel (1 l). Optionally, various filters can further supplement the cooling system, and mains connection plugs and temperature controllers for heated gas sampling probes and heated analysis lines can be installed.
The transportable case makes the GO-PKK cooling system a device for mobile use.
