The Sentry FLR sample cooler cools a sample from process streams. That may seem simple, but each FLR 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 can be 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. 

  • Minimizes cooling water needs 

  • Wide variety of exotic alloys available for corrosion resistance 

  • Retained shellside gasket reduces reassembly time 

  • Formed shell eliminates top shell flange weld interfaces 

  • Mounting bracket can be installed without removing flange bolts
