SENTRY FLR SINGLE HELICAL TUBE Sample Coolers Liquid & Slurry Solid & Powder Steam & Water The Sentry® FLR 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 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. MODELS FLR-6222 | FLR-6225 | FLR-6225U | FLR-62B3 | FLR-62B3U | FLR- 6BB3 BENEFITS The Sentry FLR sample cooler is designed for efficient and cost-effective sample cooling where higher flow or low pressure drop is required. It offers optimal service for flows below 3500 cc per minute for single phase and 2000 cc per minute for condensing heat transfer. Standard materials are 316/316L or Alloy 625 for high chloride cooling water applications. Optimized for steam condensing service.
