5-272-12-120-001

A double-wall two-pass U-bend bundle gives 5-272-12-120-001 the thermal and mechanical margin expected of Diamondback tank heater equipment in 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 12-inch diameter shell, 120-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. The unit is rated for 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 institutional water storage.
