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. Its envelope centers on a 6-inch diameter shell, 60-inch shell length, and roughly 64-1/8 inches overall in a 6-pass arrangement. That works out to about 16.7 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. The unit is rated for 150 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. This build is designated 5-266-06-060-003. Common applications are pool and storage-tower heating, hydronic HVAC converters, and oil cooling and snow melting.
