5-151-20-168-001

Built around a removable straight-tube bundle, this configuration delivers general industrial liquid-to-liquid heat transfer for demanding service. 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, 168-inch shell length, and roughly 188 inches overall in a 1-pass arrangement. That works out to about 1088 square feet of heat transfer surface on 5/8-inch O.D. tubes. As furnished, materials include cast iron bonnets, steel shell, copper tubes, and steel tubesheets. The unit is rated for 125 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-151-20-168-001. Installations range across process heating and cooling, chemical and refinery duty, and oil and quench cooling.
