5-151-20-204-001

Built around a removable straight-tube bundle, 5-151-20-204-001 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, 204-inch shell length, and roughly 224 inches overall in a 1-pass arrangement. That works out to about 1322 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. Operating limits are 125 PSI on the shell side, 125 PSI on the tube side, and 375°F maximum temperature. Installations range across oil and quench cooling, process heating and cooling, and chemical and refinery duty.
