5-261-10-024-005

For steam-to-liquid heating, the SU/WU line offers a removable U-tube bundle design; 5-261-10-024-005 sits within that range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 10-inch shell, 24-inch shell length, and roughly 29 inches overall in a 4-pass arrangement. That works out to about 25 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast brass bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. The series sees regular use in building comfort heating, instantaneous domestic water heating, and swimming pool heating.
