CHX324-4L

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. Physically, the unit runs a 3-inch shell, 24-inch shell length, and roughly 27-1/2 inches overall in a 4-pass arrangement. That works out to about 7.4 square feet of heat transfer surface on 5/8-inch O.D. tubes. That combination is cataloged as CHX324-4L. The build specifies 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. Typical duty includes engine jacket water cooling, mechanical seal cooling, and hydraulic and lube oil cooling.
