SHELL AND TUBE HEAT EXCHANGER

Heat exchangers are devices that are used to transfer heat from a liquid or gaseous fluid through a partition wall to another fluid. In many applications, shell and tube heat exchangers are the most common solution. Thanks to our optimally matched designs and materials, we not only offer a wide range of applications, but also outstanding thermal performance. This means that you always benefit from a cost-efficient and reliable solution.

Due to their usually simple design, high heat transfer capacity and easy inspection, shell and tube heat exchangers are not only widely used in chemical plants. A shell and tube heat exchanger essentially consists of a cylindrical tank (shell) into which a tube bundle is installed. This bundle is made up of tubes arranged in parallel, which are welded into round plates with holes, the tube sheets.

Shell and tube heat exchangers have at least two separate chambers: essentially the tube chamber and the shell chamber. One fluid flows through the tube bundle (tube chamber), while the other fluid flows between the tubes in the shell space. Baffles and guide plates in the shell space deflect the fluid and thus improve heat exchange. When heating steam is used, it usually flows around the tubes in the shell space, while liquids or cooling liquids to be cooled are guided through the tubes. In special cases, e.g. with very high steam pressures, this can also be routed through the tubes.
