Built around a double-wall two-pass U-bend bundle, this configuration delivers in-tank heating with steam in the tubes and cross-contamination protection for demanding service. The vented air gap between tube walls gives a visible telltale leak rather than allowing tank contents and steam to mix. Dimensionally it is a 8-inch shell unit in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, and copper (double wall) tubes. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Typical duty includes potable water storage tanks, institutional water storage, and food-grade process tanks. This build is designated 5-272-08-054-001.
