This is a heavy duty industrial shell-and-tube oil cooler made by Caterpillar. These types of coolers flow oil through one portion while coolant flows through another portion. The coolant from the cooling system flows through the cooler which cools the oil that operates at higher temperatures than the coolant does. This type of cooler is typically referred to as a liquid-to-oil cooler.
