Common Problems Solved with Sentry Sampling Systems

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

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

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

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

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

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

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

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
