5-262-04-036-012

Built around a double-wall U-tube bundle, 5-262-04-036-012 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. Its envelope centers on a 4-inch diameter shell, 36-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. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Installations range across health care and institutional plumbing, food and beverage process heating, and potable water heating.
