Sampling coolers

A sampling cooler is a thermal apparatus for safely removing, cooling and possibly condensing samples of hot fluids for the purpose of subsequent analysis. In design terms, a sampling cooler consists of a pressure vessel with an internal cooling loop. The sample medium, e.g. boiler feed water, flows through the interior of the cooling loop while the cooling medium, usually water, flows around the outside of the cooling loop. During this process, the sample medium transfers some of its heat to the cooling medium.
