Heat exchangers are unfired heat transfer equipment used in process plants. Heat exchangers are used for the transfer of heat or cold between two fluids for the purpose of heating the process, cooling the process, or condensing vapors during the process. Heat exchangers are measured in Square Feet.

• Shell and Tube - Also called a condensers and calandrias depending on the service, this type of heat exchanger has external cylinder called a shell with internal tubes that run the length of the shell. There are tube sheets on each end of the tubes sealing the shell around the tubes. There are covers on each end called heads and these can come in several configurations. The shell side has a pressure and temperature rating and the tube side has a pressure and temperature rating. They can be vertical or horizontal. Basic principal of operation is that one fluid flows through the tube and the other fluid flows around the tubes. The fluid inside the tubes can flow in a single pass or multiple passes using baffles in the heads.
