For high-temperature water heating, the HTWU line offers a removable U-tube bundle design; this configuration sits within that range. High-temperature water flows through the tube side, so the heads rather than the shell set the pressure limit. Its envelope centers on a 12-inch diameter shell, 84-inch shell length, and roughly 90 inches overall in a 2-pass arrangement. That works out to about 147 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-268-12-084-001. As furnished, materials include 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.
