SENTRY USC SINGLE HELICAL TUBE Sample Coolers Solid & Powder Steam & Water The Sentry® USC sample cooler series consists of two sample coolers designed and rated for ultra-supercritical plant applications, the Sentry TLR and Sentry FLR sample coolers. Both are optimized for steam condensing service. Both cool 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 TLR-42B5USC | FLR-62B5USC BENEFITS The Sentry TLR sample cooler is the most efficient and cost-effective sample cooler available. It offers optimal service for flows below 1800 cc per minute for single phase and below 1000 cc per minute for condensing heat transfer. Standard tube side materials are Alloy 625. 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 tube side materials are Alloy 625. FEATURES Seamless Alloy 625 tube Rated for the newest ultra-supercritical power plants (5175 psig at 1150°F [356 barg at 621°C]) Higher temperatures available depending on process pressure Double-wound helical coil design Minimizes cooling water needs Retained shellside gasket reduces reassembly time Mounting bracket can be installed without removing flange bolts ASME U stamp a
