For steam-to-liquid heating, the SU/WU line offers a removable U-tube bundle design; this configuration sits within that range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 20-inch shell, 36-inch shell length, and roughly 49-3/4 inches overall in a 2-pass arrangement. That works out to about 194 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-260-20-036-001. 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. Typical duty includes building comfort heating, instantaneous domestic water heating, and swimming pool heating.
