SU1610-4

Configured for steam-to-liquid heating, this configuration 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. The configuration measures 16 inches across the shell, 120-inch shell length, and roughly 129-5/8 inches overall in a 4-pass arrangement. That works out to about 363 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron or brass bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated SU1610-4. Installations range across radiant panel and snow-melt converters, swimming pool heating, and instantaneous domestic water heating.
