CHX536-4L

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. Its envelope centers on a 5-inch diameter shell, 36-inch shell length, and roughly 40-3/8 inches overall in a 4-pass arrangement. That works out to about 24 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as CHX536-4L. The build specifies cast iron bonnets, brass shell, copper tubes, and brass tubesheets. Design ratings run to 300 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. The series sees regular use in hydraulic and lube oil cooling, injection molding machine cooling, and engine jacket water cooling.
