Configured for steam-to-liquid heating with cross-contamination protection, this configuration carries the double-wall U-tube bundle construction that defines the Diamondback DSU/DWU range. 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. Physically, the unit runs a 8-inch shell, 24-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, copper (double wall) tubes, and naval brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-262-08-024-001.
