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 12-inch shell, 120-inch shell length, and roughly 125-1/2 inches overall in a 4-pass arrangement. That works out to about 200 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-261-12-120-002. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Common applications are building comfort heating, swimming pool heating, and instantaneous domestic water heating.
