The SENTRY TLR series are tube-in-shell sample coolers that use cooling water to bring process samples at high temperature and pressure to a safe temperature for analysis. They are used on boiler water and steam sample lines (SWAS) in thermal and combined-cycle plants, and at process sample stations in petrochemical plants and refineries.

The series is offered under model codes such as TLR-4225, TLR-4225U, TLR-42B5, TLR-4BB5 and TLR-42B5USC; the same cooler family also includes models coded TRB, TRW and WSW. Sample coolers are generally designed together with SENTRY SL panels and the TSV thermal shut-off valve.

TLR features

  • Tube-in-shell design; sample on the tube side, cooling water on the shell side
  • TLR42B5S special rating: tube material 1/4" OD Inconel 625, tube design 395 bar @ 301 °C

  • Special versions such as TLR-42B5USC (US standard) and the TLR-4225U version
