5-261-18-108-002

Built around a removable U-tube bundle, this configuration delivers steam-to-liquid heating for demanding service. 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 4-pass arrangement. That works out to about 435 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-261-18-108-002. Installations range across building comfort heating, instantaneous domestic water heating, and radiant panel and snow-melt converters.
