Shell & Tube heat exchanger

Our TEMA Class R C B Heat Exchangers are the most common type of heat exchangers that are used in oil refineries, large chemical processes, power stations and other industrial applications, as they are suited for higher-pressure applications.

Shell & tube heat exchangers are among the most popular types of exchangers, due to their flexibility. As the name implies, this type of heat exchanger consists of a bundle of tubes, fitted in a shell, with channels to lead the tube side fluid into and from the tubes.

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 of several types of tubes, such as plain or longitudinally finned tubes.

Wilton Heat Transfer Services B.V. is specialized in the thermal and mechanical engineering and manufacturing of shell & tube heat exchangers, in all kind of designs and materials, constructed per the most common internal standards.

Heat Recovery project

By reusing residual heat from the industry internally or externally, this residual heat is reused to make parts of the process more sustainable. How the residual heat can be utilized strongly depends on the capacities, temperatures and the heat requirement and residual heat availability. We provide solutions in which residual heat is used directly or with the help of an industrial heat pump. In all cases, the shell & tube heat exchanger is essential for extracting or releasing (residual) heat

Bundle replacement

Different processes require different solutions, with the most optimal bundle depending on various variables. The bundle is ultimately the heart of the heat exchanger and has been used intensively over the years. One of our services is to supply new bundles for existing heat exchangers. This can be either a like-for-like replacement or an optimized design with regard to performance and / or future maintenance.


The heat exchanger tube is the place in the heat exchanger where the heat transfer takes place. The tube is relatively thin-walled and is exposed to both process media, which can cause wear. In addition to replacing the bundle and / or the complete heat exchanger, it only involves replacing the heat exchanger tube.
