CHX648-4L

Built around a fixed-tubesheet bundle, this configuration delivers compact liquid cooling for demanding service. Small-diameter tubes pack maximum surface into a short shell, keeping the mounting footprint tight. Dimensionally it is a 6-inch shell unit, 48-inch shell length, and roughly 53 inches overall in a 4-pass arrangement. That works out to about 45 square feet of heat transfer surface on 3/4-inch O.D. tubes. As furnished, materials include cast iron bonnets, brass shell, copper tubes, and brass tubesheets. On the ratings side, expect 300 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Common applications are hydraulic and lube oil cooling, injection molding machine cooling, and mechanical seal cooling. This build is designated CHX648-4L.
