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 12-inch shell unit, 72-inch shell length in a 4-pass arrangement. It carries 3/4-inch O.D. tubes. Material selection covers cast iron bonnets, steel shell, copper (double wall) tubes, and naval brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Typical duty includes food and beverage process heating, potable water heating, and health care and institutional plumbing. This build is designated 5-262-12-072-002.
