Below is a list of Oil Coolers manufacturers from Windsor, Connecticut. Oil coolers are tube heat exchangers that are specifically designed for the transfer of heat, or thermal energy, from heated oil by carrying the oil through cooling units in order to cool it, or using the oil to absorb heat. It can be used to cool items 100°C or higher; unlike water, which has a much lower boiling point. Particularly useful for automotive or mechanical applications, oil is an electrical insulator that is used inside of or in direct contact with electrical components.
