For high-temperature water heating, the HTWU line offers a removable U-tube bundle design; this configuration sits within that range. High-temperature water flows through the tube side, so the heads rather than the shell set the pressure limit. The configuration measures 10 inches across the shell, 60-inch shell length, and roughly 65-3/8 inches overall in a 6-pass arrangement. That works out to about 56 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. The unit is rated for 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, converter duty on HTHW loops, and industrial process heating. This build is designated 5-268-10-060-003.
