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. Dimensionally it is a 12-inch shell unit, 108-inch shell length, and roughly 113-1/2 inches overall in a 2-pass arrangement. That works out to about 191 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Installations range across instantaneous domestic water heating, building comfort heating, and radiant panel and snow-melt converters. This build is designated 5-260-12-108-001.
