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. Physically, the unit runs a 4-inch shell, 60-inch shell length, and roughly 64-5/8 inches overall in a 4-pass arrangement. That works out to about 11.5 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-268-04-060-002. 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.
