5-272-10-042-001

Built around a double-wall two-pass U-bend bundle, 5-272-10-042-001 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. The configuration measures 10 inches across the shell, 42-inch shell length in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. As furnished, materials include cast iron bonnets, steel shell, and copper (double wall) tubes. On the ratings side, expect 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Installations range across domestic hot water storage under double-wall codes, institutional water storage, and food-grade process tanks.
