SU267-4

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 26-inch diameter shell, 84-inch shell length, and roughly 118-3/16 inches overall in a 4-pass arrangement. That works out to about 803 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers steel 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. The series sees regular use in building comfort heating, radiant panel and snow-melt converters, and instantaneous domestic water heating. This build is designated SU267-4.
