this configuration is a Diamondback tank heater unit built on a double-wall two-pass U-bend bundle for in-tank heating with steam in the tubes and cross-contamination protection. 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 10-inch shell, 96-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. Typical duty includes domestic hot water storage under double-wall codes, food-grade process tanks, and potable water storage tanks. This build is designated 5-272-10-096-001.
