Cat® Aftercooler is used to cool the intake air after it has been compressed by turbocharger. Cat® Aftercooler is a mechanical heat exchanger that is designed to remove the heat-of-compression from the compressed air flow and to prep the air so it can be used in air-operated equipment. These high temperatures are so intense that they can be dangerous if not lowered before the air gets pushed out. Cat® Parts are manufactured to precise specifications and are built for durability, reliability, productivity, less environmental impact and reuse.Application:Cat® Aftercooler are used in the radiator and hydraulic oil cooler system of the Cat® machine.
