For liquid-to-liquid heating and cooling, the SU/WU line offers a removable U-tube bundle design; this configuration sits within that range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. Dimensionally it is a 4-inch shell unit, 48-inch shell length, and roughly 52-7/8 inches overall in a 4-pass arrangement. That works out to about 9.19 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as 5-266-04-048-005. Standard construction uses 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 300°F maximum temperature. Typical duty includes pool and storage-tower heating, condensate cooling, and oil cooling and snow melting.
