TCW-654

Configured for in-tank heating with boiler water in the tubes, TCW-654 carries the two-pass U-bend bundle construction that defines the TCS/TCW tank heater range. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Its envelope centers on a 6-inch diameter shell, 54-inch shell length, and roughly 51-1/8 inches overall in a 2-pass arrangement. That works out to about 19.7 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
