8. Common Problems Solved withSentry Sampling Systems

9. Problem #1: Non-constant Flow to Analyzers • Sentry VREL and BPR/RV in Tandem • VREL Reduces Bulk of Pressure • BPR/RV Does Fine Pressure Control • Shock Absorber- Extra Flow through BPR/RV • Flat Flow vs. Pressure Curve

10. Problem #2: Poor Sample Temperature Control • Competitor’s Bath Systems are not “Isothermal” • Competitor’s Bath Systems typically only cool • Bath has Poor Approach Temperature due to Low Turbulence • Sentry System uses Dedicated Secondary Coolers • High Surface Area- Close Approach Temperature • +/- 0.25 C control with Chiller; 25+/- 0.5 C through Sentry Coolers

11. Problem #3: Plugging Sample Lines • Typically caused by Oversized Sample Lines • Also Caused by Low Flow • Sentry Properly Sizes Coolers with Cooler Program • Sentry Recommends Low Pressure Blowdown

12. Problem #4: Samples Too Hot • Many Times Competitor’s Coolers are Undersized • Computer Sizing Can Eliminate • Sentry has over 30 Cooler Models, Competitors have 2 to 4 models • Sentry models include 0.11, 0.16, 0.22, 0.33, & 0.44 Square Meter Surface Area

13. Problem #5: Rusting/Patched Panel Front • Most Competitor’s Panels have Painted Carbon Steel Fronts • Sentry Panel has Corrosion Resistant Modular 304 SS Front • Modular Front Allows Future Changes Without Patching the Panel Front

14. Problem #6: Too Low Sample Flow • Competitor’s Don’t Size Coolers Properly • Steam Samples, Especially Low Pressure Steam, Needs High Capacity Sample Cooler • Sentry has Special High Surface Area/Low Pressure Drop Coolers- FLF-6222/FXF-6223

15. Problem #7: Thermal Excursions • Thermal excursions can cause operator injury, damage cells, analyzers and other components and discharge of steam to atmosphere • Thermal excursions can be caused by loss of cooling water, high sample flow rate, fouled or plugged sample cooler or high cooling water temperature • Thermal Shut Off Valves - requires no pneumatic or electrical power, re-settable latching design, positive position indication, compact package • Optional switch for remote indication

16. Problem #8: Multiple Independent Analyzers • Calibration differences can occur between independent analyzers • Calibration requires valuable time • Sharing one analyzer reduces calibration differences, calibration time, consumable usage, capital cost • Sentry Sequencer is a proven method of analyzer sharing

17. Kinds of Projects • Complete Turnkey • Panel Upgrade with Components • Some Local Content- Conditioning by Sentry/Analyzers Supplied Locally

18. Get Sentry Specified • Sentry Panel Specification • Specify Sentry Components • Require Dedicated Secondary Coolers • Require Flanged, single gasket, 304 SS shell, 304 SS Bolts, and 316 SS Tubing • Require Sentry VREL on High Pressure Lines (> 35 Barg) • Require Sentry TSV & BPR/RV

19. Sentry Sampling Systems Set the World Standard for Quality and Performance
