TCW-1478

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. Its envelope centers on a 14-inch diameter shell, 78-inch shell length, and roughly 79-1/2 inches overall in a 2-pass arrangement. That works out to about 190 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as TCW-1478. Standard construction uses 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.
