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. Its envelope centers on a 18-inch diameter shell, 108-inch shell length, and roughly 120-1/2 inches overall in a 2-pass arrangement. That works out to about 435 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast brass bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and N/A maximum temperature. Typical duty includes instantaneous domestic water heating, swimming pool heating, and building comfort heating. This build is designated 5-261-18-108-004.
