How compact tube heat exchangers work
A compact tube design, which we utilise in our compact tube heat exchangers, aims to optimise the heat transfer rate, allowing for smaller heat transfer areas. We achieve this by using fins where the shell side fluid flow and heat transfer properties would not usually generate a high heat transfer coefficient.
This means we can design and manufacture a compact tube heat exchanger that is still highly efficient. These can be made from various materials to suit different applications.

Compact tube heat exchanger applications
The most common application for compact tube heat exchangers (sometimes called CHE) is the cooling of gases at a pressure in the region of 5 to 10 bar. High-pressure blowers generate significant heat as the gas is compressed and must be cooled before moving to the next process stage. Using fins, the achieved heat transfer increase means that we can reduce the overall unit’s diameter and/or length without diminishing the performance.
This makes them suitable for a wide range of industries, including defence, energy and power, and marine. Furthermore, it needs to be added that compact shell & tube heat exchangers have been seen as a product of choice in Waste Heat Recovery (WHR) systems and Organic Rankine Cycle (ORC).
We can manufacture our compact designs from various materials, including those with corrosion-resistant properties such as Hastelloy, Inconel and others. Thanks to this, applications include chemical plants and other contexts where the heat exchanger must handle corrosive materials such as acids or petrochemicals.

Compact heat exchanger design considerations
We ensure the optimum heat transfer in our compact tube heat exchanger designs while considering the corrosion potential of the shell side fluid. How? By matching the fin and tube materials.
We can minimise the cooler footprint and ensure optimum utilisation of the available pressure drop. We do so by adjusting tube sizes, layout, pitch and passes accompanied with fin density, in parallel with shell-side flow passes, and appropriate baffle type and arrangement selection.
Systems that involve a high-pressure gas stream, using a liquid as the coolant, would not usually be able to generate a high heat transfer coefficient. Traditionally, they would have to be larger or settle for a less efficient process. However, in these cases, the optimised fin design in our compact tube heat exchangers may be a great improvement.
