Built around a double-wall U-tube bundle, this configuration delivers steam-to-liquid heating with cross-contamination protection for demanding service. 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. Dimensionally it is a 8-inch shell unit, 72-inch shell length in a 2-pass arrangement. It carries 3/4-inch O.D. tubes. Standard construction uses 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 5-262-08-072-001. Installations range across food and beverage process heating, domestic hot water where codes require double-wall separation, and potable water heating.
