5-272-04-024-001

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 4-inch diameter shell in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-272-04-024-001. The build specifies 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. Installations range across institutional water storage, domestic hot water storage under double-wall codes, and potable water storage tanks.
