Configured for in-tank heating with steam in the tubes and cross-contamination protection, this configuration carries the double-wall two-pass U-bend bundle construction that defines the Diamondback tank heater range. The vented air gap between tube walls gives a visible telltale leak rather than allowing tank contents and steam to mix. The configuration measures 12 inches across the shell, 48-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, potable water storage tanks, and domestic hot water storage under double-wall codes. This build is designated 5-272-12-048-001.
