this configuration 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. The configuration measures 4 inches across the shell, 36-inch shell length, and roughly 40-5/8 inches overall in a 4-pass arrangement. That works out to about 6.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-268-04-036-002. Material selection covers 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. Common applications are high-temperature hot water distribution, industrial process heating, and campus and district energy systems.
