To review the water quality in steam generation, samples should be taken from the fresh water, feed water, boiler water and, if possible, the condensate. Apart from the fresh water, all samples are hot and partially pressurised.
Measurement of the water parameters under temperature may cause falsified results. Waiting until the samples have cooled off may cause changes in the water. Boiler water and condensate cannot be removed easily because they are pressurised. The sampling cooler is ideal for cooling and taking water samples. To perform these measurements better, lines are placed from the sampling locations to the sampling cooler in which the sample water is cooled with cold water using a heat exchanger.
A sampling cooler is always recommended but absolutely if the water parameters are difficult.
