The Sample Cooler is a shell and tube heat exchanger, used to cool the sample from a process stream to the required temperature conditions for safe and analysis.

It is one of the most critical components of a sampling system suitable for most applications in liquid, gas or steam process. The sample to be cooled flows through the tube side of the cooler, and the cooling fluid, usually water, flows through the shell side. The cooled sample then is taken to a laboratory for analysis or piped to in-line process instrumentation for continuous monitoring of properties such as conductivity, pH or other chemical constituents.
