For steam-to-liquid heating, the SU/WU line offers a removable U-tube bundle design; 5-260-04-084-012 sits within that range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 4-inch shell, 84-inch shell length, and roughly 89 inches overall in a 4-pass arrangement. That works out to about 16.3 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast iron bonnets, steel shell, copper tubes, and steel tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Installations range across radiant panel and snow-melt converters, building comfort heating, and swimming pool heating.
