5-266-04-036-004

Configured for liquid-to-liquid heating and cooling, 5-266-04-036-004 carries the removable U-tube bundle construction that defines the SU/WU range. Pumped boiler water circulates through the baffled shell against the tube-side fluid. The configuration measures 4 inches across the shell, 36-inch shell length, and roughly 40-7/8 inches overall in a 2-pass arrangement. That works out to about 6.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. Standard construction uses cast brass bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Installations range across oil cooling and snow melting, condensate cooling, and pool and storage-tower heating.
