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. Physically, the unit runs a 4-inch shell, 36-inch shell length, and roughly 41 inches overall in a 2-pass arrangement. That works out to about 6.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. The series sees regular use in swimming pool heating, building comfort heating, and radiant panel and snow-melt converters. This build is designated 5-260-04-036-011.
