5-272-06-042-001

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. Its envelope centers on a 6-inch diameter shell in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-272-06-042-001. The build specifies cast iron bonnets, steel shell, and copper (double wall) tubes. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. The series sees regular use in food-grade process tanks, potable water storage tanks, and institutional water storage.
