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. Its envelope centers on a 10-inch diameter shell, 84-inch shell length, and roughly 89-3/8 inches overall in a 2-pass arrangement. That works out to about 101 square feet of heat transfer surface on 3/4-inch O.D. tubes. 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. The series sees regular use in campus and district energy systems, converter duty on HTHW loops, and high-temperature hot water distribution. This build is designated 5-268-10-084-001.
