For steam-to-liquid heating, the SU/WU line offers a removable U-tube bundle design; this configuration sits within that range. Steam condenses in the single-pass shell while the heated fluid travels the tubes. The configuration measures 6 inches across the shell, 84-inch shell length, and roughly 88-1/8 inches overall in a 4-pass arrangement. That works out to about 31.5 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 300°F maximum temperature. This build is designated 5-261-06-084-005. Typical duty includes building comfort heating, swimming pool heating, and radiant panel and snow-melt converters.
