Shell & tube heat exchangers
What are tubular heat exchangers?
A tubular heat exchanger allows you to recover heat from a medium (e.g. water), by removing the heat and transferring it to another medium (e.g. gas). In tubular heat exchangers, the first medium passes through tubes and the second medium passes through a jacket surrounding the tubes.
When to use?
For which media: heat transfer between liquids and/or gases.
When? Tubular heat exchangers can withstand higher temperatures and pressures: to 500 °C and up to 1000 bar. At the same time, they can handle media with larger particles (3-4 mm and more).
Which applications and sectors?
Typical applications: evaporators (to convert liquid to gas) and condensers (to convert gas to liquid). Tubular heat exchangers are more resistant to pressure differences that may arise. Also, oil coolers are often used because the heat exchangers are easy to clean (with the correct TEMA design).
Typical sectors: HVAC, chemicals, hydraulics, petrochemicals, food, etc.
Why via TAS?
TAS will ensure you get a recommendation for the right tubular heat exchanger. This recommendation perfectly matches the required standard (certification), and it will be precisely tailored to your project. If you want a shell & tubular heat exchanger, please fill in this questionnaire first. We will then immediately be able to work out which heat exchanger is most suitable for your application. You can choose from several brands.

Standard shell-and-tube heat exchangers
Our standard shell-and-tube heat exchanger in a modular system construction is mainly used for cooling liquids such as lubricating oil and hydraulic oil or water, as well as for heating by means of saturated steam. Water, water/glycol mixtures or seawater can be used as the cooling medium.
More than 200 graduated construction sizes in different materials provide the basis for optimal and detailed type selection.
Standardisation enables us to guarantee shorter delivery times.
Custom made shell-and-tube heat exchangers
Our custome-made, individual solutions in the field of shell-and-tube heat exchangers find their main application in projects.
Our customer's requirements for the products are always our main focus.
We review company data, building regulations and specifications during project engineering and use this information to deliver the optimum, thermodynamic device.
We attach great importance to a technically and economically optimised solution that fully meets our customer's requirements and the requirements for maximum plant safety and efficiency.
After all, at operating pressures of up to 600 bar, every weld counts.
Moreover, strict quality controls from goods receipt to dispatch ensure that the manufactured product meets your requirements with regard to function, quality and documentation.
We supply not only the heat exchanger itself, but also the documentation you must obtain according to the Pressure Equipment Directive (PED) and standards organisation ASME.
Corrugated tubular heat exchangers
Do you need a tubular heat exchanger to transfer more heat while remaining as compact as possible? Then a tubular heat exchanger with corrugated tubes may be the right solution. The corrugated tubes create turbulence, causing the heat transfer to increase while ensuring the heat exchanger can remain smaller.
At the same time, the corrugation of the tubes creates a self-cleaning effect, reducing contamination on the pipe surface. This means this type of tubular heat exchanger is more compact and has less downtime.
Different variants
Either the exchanger consists of two concentric corrugated tubes (XTUBE® Monotube). The medium to be cooled passes through the inner tube, the cooling medium flows through the space between the inner and the outer tube.
A tubular heat exchanger can also consist of three or four concentric corrugated tubes (XTUBE® Multitube) fitted inside each other, like a Matryoshka doll. The medium is thereby heated or cooled from the outside and inside by, for instance, the medium to be cooled flowing through the middle tube (around the third inner tube that contains cooling medium).
Finally, the exchanger can consist of a bundle of corrugated tubes (XTUBE® Tripletube) encased in a larger corrugated tube. The medium to be cooled flows through the bundle of tubes, the cooling medium flows through the larger tube.
