CHXS648-4L

Built around a fixed-tubesheet bundle, this configuration delivers compact liquid cooling in corrosive service for demanding service. It shares the compact CHX envelope while targeting service that would attack a standard cooler. Physically, the unit runs a 6-inch shell, 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. That combination is cataloged as CHXS648-4L. The build specifies cast iron bonnets, steel shell, copper tubes, and brass tubesheets. Operating limits are 300 PSI on the shell side, 150 PSI on the tube side, and 300°F maximum temperature. Typical duty includes mechanical seal cooling, hydraulic and lube oil cooling, and chemical and food process cooling.
