TCW-884

Configured for in-tank heating with boiler water in the tubes, TCW-884 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. Physically, the unit runs a 8-inch shell, 84-inch shell length, and roughly 82-1/4 inches overall in a 2-pass arrangement. That works out to about 58 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast iron or brass bonnets, steel shell, copper tubes, and steel or brass tubesheets. Design ratings run to 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature.
