5-260-12-072-001

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. Physically, the unit runs a 12-inch shell, 72-inch shell length, and roughly 77-1/2 inches overall in a 2-pass arrangement. That works out to about 126 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies 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. This build is designated 5-260-12-072-001. Common applications are radiant panel and snow-melt converters, swimming pool heating, and building comfort heating.
