5-271-12-060-002

A two-pass U-bend bundle gives 5-271-12-060-002 the thermal and mechanical margin expected of TCS/TCW tank heater equipment in in-tank heating with steam in the tubes. The bundle mounts through a collar in the tank wall and heats the surrounding fluid by natural convection. Physically, the unit runs a 12-inch shell, 60-inch shell length, and roughly 60-1/4 inches overall in a 2-pass arrangement. That works out to about 104 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies 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 boiler feed and condensate tanks, process tank heating, and hot water storage tanks.
