Functional description:
The Process-Analytic-Cooler model GT5.Ex 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.
The collected condensate is separated via the Water-Trap (option).
The Water-Trap offers an additional protection against condensate breakthrough and dust deposits with the integrated membrane technology of the SUN-Control-Analytik. After the Process-Analytic-Cooler you have a dry and dust-free sample gas corresponding to dew point for your high quality gas analyser/gas sensor at your availability.
The Process-Analytic-Cooler can be used also for cooling of fluids.
