CHX648-2L

This configuration is a CHX compact unit built on a fixed-tubesheet bundle for compact liquid cooling. 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 52-3/4 inches overall in a 2-pass arrangement. That works out to about 45 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as CHX648-2L. Material selection covers cast iron bonnets, brass shell, copper tubes, and brass tubesheets. The unit is rated for 300 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Installations range across mechanical seal cooling, hydraulic and lube oil cooling, and engine jacket water cooling.
