The Vira sample cooler is a small heat exchanger which has been specifically designed for taking high quality samples quickly and safely by using cold mains water to cool the sample taken from the boiler.
Samples taken for measure conductivity of the boiler water are very hot approx. 160 °C (320 °F) and contains flash steam. It is difficult to take sample without a sample cooler and it causes incorrect measurements. Vira sample coolers provide safe, easy and accurate sampling.
A properly taken cool sample is required for analysis. When taking a sample out of boiler water, it is important to ensure that it is a proper sample that represents.
It is not recommended to ;
Most of the operators install a sample cooler connection from TDS blowdown, and it is generally possible to obtain a true sample from this location.
It is also not recommended to draw water out of boiler by not using sample cooler, it may cause to create flash steam since its pressure is reduced. It may also be highly dangerous for the operator. Besides, analysis may give quite wrong results because of the flash steam concentration of the sample.
