5-262-12-036-001

this configuration is a Diamondback DSU/DWU unit built on a double-wall U-tube bundle for steam-to-liquid heating with cross-contamination protection. An atmospheric air gap between the inner and outer tube vents any breach to the outside, giving a visible telltale leak instead of silent mixing. Its envelope centers on a 12-inch diameter shell, 36-inch shell length in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. That combination is cataloged as 5-262-12-036-001. The build specifies cast iron bonnets, steel shell, copper (double wall) tubes, and naval brass tubesheets. The unit is rated for 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Installations range across food and beverage process heating, health care and institutional plumbing, and potable water heating.
