5-261-16-120-004

this configuration is a SU/WU unit built on a removable U-tube bundle for steam-to-liquid heating. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Its envelope centers on a 16-inch diameter shell, 120-inch shell length, and roughly 129-5/8 inches overall in a 2-pass arrangement. That works out to about 380 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast brass bonnets, steel shell, copper tubes, and brass tubesheets. The unit is rated for 150 PSI on the shell side, and 150 PSI on the tube side. Installations range across building comfort heating, instantaneous domestic water heating, and radiant panel and snow-melt converters. This build is designated 5-261-16-120-004.
