5-272-14-066-001

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. Physically, the unit runs a 14-inch shell, 66-inch shell length in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. Material selection covers cast iron bonnets, steel shell, and copper (double wall) tubes. The unit is rated for 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-272-14-066-001. Installations range across food-grade process tanks, domestic hot water storage under double-wall codes, and institutional water storage.
