The Sentry FXR sample cooler cools a sample from a process stream. It may seem simple, but it is a uniquely designed small tube in a shell heat exchanger. The sample cooler is compact and provides broad application flexibility through the use of a variety of sample tube materials. 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.

The Sentry FXR sample cooler is designed for efficient and cost-effective sample cooling where higher flow is required. It offers optimal service for flows below 5000 cc per minute for single phase and 2000 cc per minute for condensing heat transfer. Standard tube side materials are 316/316L SS or Alloy 625 for high chloride cooling water applications.
