S&T Heat Exchanger

An S&T heat exchanger is crucial for the efficient functioning of a number of different systems on a ship including the propulsion plant, auxiliary power generation system, starting air system, fuel injection system, AC system, fresh water system and the refrigeration system.

Also known as a shell and tube heat exchanger, this is a device in which two fluids circulate at different temperatures - one through the tubes within the shell and the other fluid in the shell itself. This action transfers heat between the two fluids.
