CHX314-4S

For compact liquid cooling, the CHX compact line offers a fixed-tubesheet bundle design; CHX314-4S sits within that range. Small-diameter tubes pack maximum surface into a short shell, keeping the mounting footprint tight. Physically, the unit runs a 3-inch shell, 14-inch shell length, and roughly 17-1/4 inches overall in a 4-pass arrangement. That works out to about 4.3 square feet of heat transfer surface on 5/8-inch O.D. tubes. The build specifies 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 hydraulic and lube oil cooling, engine jacket water cooling, and mechanical seal cooling.
