The Diamondback tank heater platform pairs a double-wall two-pass U-bend bundle with proven shell-side baffling, and this configuration applies that design to 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. Its envelope centers on a 8-inch diameter shell in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-272-08-018-001. The build specifies cast iron bonnets, steel shell, and copper (double wall) tubes. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
