5-261-18-036-005

Built around a removable U-tube bundle, 5-261-18-036-005 delivers steam-to-liquid heating for demanding service. Steam condenses in the single-pass shell while the heated fluid travels the tubes. Dimensionally it is a 18-inch shell unit, 36-inch shell length, and roughly 48-1/2 inches overall in a 4-pass arrangement. That works out to about 148 square feet of heat transfer surface on 3/4-inch O.D. tubes. The build specifies cast brass bonnets, steel shell, copper tubes, and brass tubesheets. On the ratings side, expect 150 PSI on the shell side, 150 PSI on the tube side, and N/A maximum temperature. Typical duty includes swimming pool heating, building comfort heating, and instantaneous domestic water heating.
