Systems for cooling gas in order to separate the contained water vapor. By cooling with units from the GO-PK series, you obtain accurate measured results and reduce washout losses.
Sample gas preparation before gas analysis generally requires, in most cases, cooling the gas in order to separate the contained water vapor in addition to other measures. During the cooling process, it is essential to prevent washout losses of target substances in gas analyses. This is necessary to obtain measurement results that are as accurate as possible.
In practice, the goal is to achieve negligible levels of absorption of the target substances in the resulting condensate. Ideally, these values are either unmeasurable, or fall within the measurement tolerances of the analyzers.
This is achieved by condensing the water vapor in the gas completely The condensate flows downwards and is removed, while the gas exits at the top. For this purpose, the geometry of the condensate separator / heat exchanger in the cooling block of a cooler is of particular importance.
As a variation of the cyclone principle of a solid separator, the shape of the contact separator and the resulting gas routing in the GO-PK and GO-EPK measurement gas cooler enforce the gas into immediate contact with the coldest point of the wall.
The sudden cooling to approx. 5 °C causes most of the condensate to draindownward in the heat exchanger, while the dehumidified measurement gas is directed upward.
The small internal surface area and low volume of the heat exchanger further help reduce loss in substance.
The measurement gas coolers GO-PK and GO-EPK can be equipped with one or two heat exchangers. Their compact construction allows easy installation in analyzer cabinets, while the GO-EPK model can be integrated into 19-inch rackmount chassis.
The measurement gas coolers GO-PK and GO-EPK are also an essential component of the GO-PP, GO-PKK, GO-PKF cooling systems and the GOT, GOE, and GOM measurement gas processing.
