TCS-684

Built around a two-pass U-bend bundle, this configuration delivers in-tank heating with steam in the tubes for demanding service. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. The configuration measures 6 inches across the shell, 84-inch shell length, and roughly 81-1/8 inches overall in a 2-pass arrangement. That works out to about 31.5 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated TCS-684.
