5-268-08-108-002

Configured for high-temperature water heating, 5-268-08-108-002 carries the removable U-tube bundle construction that defines the HTWU range. High-temperature water flows through the tube side, so the heads rather than the shell set the pressure limit. Dimensionally it is a 8-inch shell unit, 108-inch shell length, and roughly 113-1/8 inches overall in a 4-pass arrangement. That works out to about 75 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses 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 campus and district energy systems, industrial process heating, and converter duty on HTHW loops.
