5-272-12-054-001

Built around a double-wall two-pass U-bend bundle, 5-272-12-054-001 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. Physically, the unit runs a 12-inch shell, 54-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. Operating limits are 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Common applications are food-grade process tanks, institutional water storage, and domestic hot water storage under double-wall codes.
