For in-tank heating with boiler water in the tubes, the TCS/TCW tank heater line offers a two-pass U-bend bundle design; 5-276-08-066-002 sits within that range. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Its envelope centers on a 8-inch diameter shell, and roughly 64-1/4 inches overall in a 2-pass arrangement. That works out to about 45 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. Common applications are hydronic-fed storage systems, process tank heating, and domestic water storage heating.
