5-261-18-120-005

For steam-to-liquid heating, the SU/WU line offers a removable U-tube bundle design; 5-261-18-120-005 sits within that range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Physically, the unit runs a 18-inch shell, 120-inch shell length, and roughly 132-1/2 inches overall in a 4-pass arrangement. That works out to about 483 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses 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 N/A maximum temperature. Common applications are instantaneous domestic water heating, swimming pool heating, and radiant panel and snow-melt converters.
