SENTRY Supercritical Sample Cooler (TLR / FLR)

TLR and FLR models are small-tube shell-and-tube heat exchangers designed for steam and condensate samples from ultra-supercritical plants. The sample flows on the tube side and the cooling fluid, usually water, on the shell side. The cooled sample goes to the laboratory or to in-line instruments monitoring parameters such as conductivity and pH.

Values

• Tube: up to 5175 psi and 1150 °F (357 bar, 621 °C); shell: 450 psi and 650 °F (31 bar, 343 °C).
• Tubes 1/4 or 3/8 inch seamless Alloy 625; shell 304/304L or 316/316L stainless steel.
• Heat transfer surface 0.22 m² for TLR, 0.33 m² for FLR.
• ASME U stamp and material test reports (MTR) are standard.
• Cooling water consumption is kept low.

Choosing Supercritical TLR / FLR

All values vary according to the material selected. The manufacturer states that the cooler meets the pressures and temperatures required at new ultra-supercritical plants; because tube and shell values differ, the pressure limit on the cooling water side should be checked separately.

Tetra selects TLR or FLR according to sample flow and cooling water conditions and supplies it with certificate documents. Line mounting and pressure tests, along with the supply of parts needed in maintenance periods, are also managed in Türkiye.
