For ultra-supercritical plant applications, these samplers (Senrtry TLR and Sentry FLR) are optimized for steam and condesnsing services and used to cool a sample from a specially designed process stream.

For ultra-supercritical plant applications, these two sample coolers are optimized for steam and condensing services. These sample coolers (Sentry TLR and Sentry FLR) are used to cool a sample from a process stream with a specially designed small tube in a shell heat exchanger. The to-be-cooled sample flows through the tube side of the cooler, and then the cooling liquid (usually water) flows through the shell side. The cooled sample can then 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 requirements
Rated for the newest ultra-supercritical power plants (5175 psig at 1150°F [356 barg at 621°C])
ASME U stamp and MTRs standard
