For in-tank heating with steam in the tubes and cross-contamination protection, the Diamondback tank heater line offers a double-wall two-pass U-bend bundle design; 5-272-06-012-001 sits within that range. The vented air gap between tube walls gives a visible telltale leak rather than allowing tank contents and steam to mix. Dimensionally it is a 6-inch shell unit 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. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Typical duty includes food-grade process tanks, institutional water storage, and potable water storage tanks.
