5-151-20-120-001

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, 120-inch shell length, and roughly 140 inches overall in a 1-pass arrangement. That works out to about 777 square feet of heat transfer surface on 5/8-inch O.D. tubes. Standard construction uses cast iron bonnets, steel shell, copper tubes, and steel tubesheets. Design ratings run to 125 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. This build is designated 5-151-20-120-001. Common applications are condenser and evaporator service, oil and quench cooling, and chemical and refinery duty.
