5-272-08-066-001

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. Dimensionally it is a 8-inch shell unit in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-272-08-066-001. As furnished, materials include cast iron bonnets, steel shell, and copper (double wall) tubes. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Common applications are institutional water storage, food-grade process tanks, and potable water storage tanks.
