Built around a removable U-tube bundle, this configuration delivers liquid-to-liquid heating and cooling for demanding service. 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 4-pass arrangement. That works out to about 6.8 square feet of heat transfer surface on 3/4-inch O.D. tubes. Material selection covers cast iron 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 hydronic HVAC converters, condensate cooling, and oil cooling and snow melting. This build is designated 5-266-04-036-002.
