Special heat exchangers
What are special heat exchangers?
We not only supply standard plate and tubular heat exchangers, we also supply special heat exchangers: oil-air coolers, Hybrid tubular plate heat exchangers and spiral heat exchangers. Choose one of these options below to learn more about it.
Why via TAS?
Because we will ensure you get the right heat exchanger. Precisely tailored to your project. Not only a plate or tubular heat exchanger, but a special heat exchanger if that turns out to be the best option. Our specialists will be pro-active when working with you. You can choose from the range supplied by this brand together.

Product variations
Hybrid tubular plate heat exchangers
These heat exchangers have laser-welded plates in a metal housing. These are used for high heat transfer, and they normally have a very compact design.
When to use?
- For which media: heat transfer between liquids and/or gases.
- When? These heat exchangers provide better protection against high temperatures and pressure: from -200 to 900 °C, up to 60 bar or vacuum. They are also resistant to high differential pressures and aggressive media. The chance of leakage is therefore small, and they can withstand tough working conditions.
Which applications?
- Typical applications: often liquid-liquid transfer, but also evaporators or condensers, even at high pressure and vacuum.
- Typical sectors: chemistry, petro-chemistry, food.
How does this hybrid heat exchanger work?
- The functionality of the VAU hybrid heat exchanger can be seen in the animation below.

Oil-air coolers
This solution uses air to cool oil. We supply a wide range of standard units that are suitable for most applications that require this type of cooling.
When to use?
If the temperature of the ambient air is far enough below the desired oil temperature, the oil-air cooler can be used to cool it. Is the ambient air temperature expected for your project too close? Then we suggest using an oil-air cooler that cools the oil by passing it through a plate or a tubular heat exchanger cooled with water or water glycol.
Which applications and sectors?
- Typical application: almost only hydraulics.
- Typical sectors: chemistry, petro-chemistry, food.
Spiral heat exchangers
These heat exchangers have coiled tubes that form a spiral shape. The devices are the best alternative to the classic shell & tubular heat exchanger. After all, the solution is not only compact and robust, but also transfers heat very well.
When to use?
- For which media: heat transfer between liquids and/or gases.
- When? Not only is the heat transfer high, the maintenance costs are also lower. The tubes rarely clog, and they essentially clean themselves. If you do find that you need to clean the heat exchanger, open the lid to gain access to the entire heat exchange surface.
Which applications and sectors?
- Typical applications: cooling or heating wastewater or pulp in the paper industry, cooling or heating granulates in the PVC industry.
- Typical sectors: chemistry, petro-chemistry, food.
