The Sentry TLR sample cooler/heat exchanger cools a sample from a process stream. It may seem simple, but it is a uniquely designed small tube and shell heat exchanger. The sample to be cooled flows through the tube side of the cooler, and the cooling fluid 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.

The Sentry TLR sample cooler is the most efficient and cost-effective sample cooler available. Offers optimal service for flows below 1800 cc per minute for single phase and below 1000 cc per minute for condensing heat transfer. The Sentry TLR sample cooler is optimized for steam condensing service.
