5-275-10-036-001

A two-pass U-bend bundle gives this configuration the thermal and mechanical margin expected of TCS/TCW tank heater equipment in in-tank heating with boiler water in the tubes. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. The configuration measures 10 inches across the shell, 36-inch shell length, and roughly 35-3/8 inches overall in a 2-pass arrangement. That works out to about 42 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-275-10-036-001. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
