CHX660-4L

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. Its envelope centers on a 6-inch diameter shell, 60-inch shell length, and roughly 65 inches overall in a 4-pass arrangement. That works out to about 56 square feet of heat transfer surface on 3/4-inch O.D. tubes. That combination is cataloged as CHX660-4L. Standard construction uses 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. Typical duty includes injection molding machine cooling, engine jacket water cooling, and hydraulic and lube oil cooling.
