TCS-854

this configuration is a TCS/TCW tank heater unit built on a two-pass U-bend bundle for 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. Its envelope centers on a 8-inch diameter shell, 54-inch shell length, and roughly 52-1/4 inches overall in a 2-pass arrangement. That works out to about 36.5 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. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 375°F maximum temperature. This build is designated TCS-854.
