Steam & Water

The Sentry® TRB 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.

MODEL

TRB-4222

BENEFITS

The Sentry TRB sample cooler is compact and provides the industrial boiler user with a cost-effective and efficient sampling alternative. Its small profile allows for easy installation on or near the boiler. It offers optimal service for flows below 1200 cc per minute for single phase heat transfer. Standard tube side material is 300 series stainless steel.

NOTE: Not recommended for steam condensing service. See TLR, FLR, FXR series sample coolers for steam applications.
