Heat Exchanger

A Heat Exchanger is a device built for efficient heat transfer from one medium to another. A solid wall may separate the media, so that they never mix, or they may be in direct contact. This is widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment.

Shell and Tube Heat Exchanger The shell & tube heat exchanger is the most common type and is used in oil refineries and large chemical processes. It is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed by several types of tubes: plain, longitudinally finned, and other types.

Plate Heat Exchanger All plate heat exchangers look similar on the outside. The difference lies on the inside, in the details of the plate design and the sealing technologies used. Hence, when evaluating a plate heat exchanger, it is very important to not only explore the details of the product being supplied, but also analyse the level of research and development carried out by the manufacturer and the post-commissioning service and spare parts availability.
