5-261-04-084-005

Configured for steam-to-liquid heating, 5-261-04-084-005 carries the removable U-tube bundle construction that defines the SU/WU range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 4-inch shell, 84-inch shell length, and roughly 89 inches overall in a 4-pass arrangement. That works out to about 16.3 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast brass 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 300°F maximum temperature. Installations range across swimming pool heating, building comfort heating, and instantaneous domestic water heating.
