5-275-12-108-001

this configuration is a TCS/TCW tank heater unit built on a two-pass U-bend bundle for 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. Physically, the unit runs a 12-inch shell, 108-inch shell length, and roughly 108-1/4 inches overall in a 2-pass arrangement. That works out to about 191 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-275-12-108-001. As furnished, materials include 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.
