5-261-20-060-002

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. The configuration measures 20 inches across the shell, 60-inch shell length, and roughly 73-3/4 inches overall in a 4-pass arrangement. That works out to about 314 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-261-20-060-002. Common applications are instantaneous domestic water heating, radiant panel and snow-melt converters, and building comfort heating.
