5-268-10-072-001

5-268-10-072-001 is a HTWU unit built on a removable U-tube bundle for high-temperature water heating. High-temperature water flows through the tube side, so the heads rather than the shell set the pressure limit. Its envelope centers on a 10-inch diameter shell, 72-inch shell length, and roughly 77-3/8 inches overall in a 2-pass arrangement. That works out to about 86 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. Design ratings run to 150 PSI on the shell side, 400 PSI on the tube side, and 375°F maximum temperature. Installations range across converter duty on HTHW loops, industrial process heating, and campus and district energy systems.
