For in-tank heating with boiler water in the tubes, the TCS/TCW tank heater line offers a two-pass U-bend bundle design; this configuration sits within that range. 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, and roughly 39-1/8 inches overall in a 2-pass arrangement. That works out to about 15 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Common applications are domestic water storage heating, process tank heating, and hot water storage tanks. This build is designated 5-275-06-042-001.
