5-151-20-144-001

This configuration is a OC straight tube unit built on a removable straight-tube bundle for general industrial liquid-to-liquid heat transfer. An internally packed floating rear tubesheet absorbs differential expansion, and the bundle pulls for straight-through mechanical tube cleaning. Physically, the unit runs a 20-inch shell, 144-inch shell length, and roughly 164 inches overall in a 1-pass arrangement. That works out to about 932 square feet of heat transfer surface on 5/8-inch O.D. tubes. The build specifies cast iron bonnets, steel shell, copper tubes, and steel tubesheets. On the ratings side, expect 125 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-151-20-144-001.
