Built around a removable U-tube bundle, this configuration delivers high-temperature water heating for demanding service. High-temperature water flows through the tube side, so the heads rather than the shell set the pressure limit. Its envelope centers on a 4-inch diameter shell, 48-inch shell length, and roughly 52-5/8 inches overall in a 4-pass arrangement. That works out to about 9.19 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. Operating limits are 150 PSI on the shell side, 400 PSI on the tube side, and 375°F maximum temperature. Installations range across campus and district energy systems, industrial process heating, and converter duty on HTHW loops. This build is designated 5-268-04-048-002.
