A removable U-tube bundle gives this configuration the thermal and mechanical margin expected of HTWU equipment in 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 8 inches across the shell, 108-inch shell length, and roughly 113-1/8 inches overall in a 2-pass arrangement. That works out to about 75 square feet of heat transfer surface on 3/4-inch O.D. tubes. 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. The series sees regular use in high-temperature hot water distribution, converter duty on HTHW loops, and industrial process heating. This build is designated 5-268-08-108-001.
