The HTWU platform pairs a removable U-tube bundle with proven shell-side baffling, and this configuration applies that design to 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 8-inch diameter shell, 60-inch shell length, and roughly 65-1/8 inches overall in a 6-pass arrangement. That works out to about 33 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-268-08-060-003. 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.
