Air Preheater

Plate Type Heat Exchangers

Our plate type heat exchangers can be used for all types of applications where large and small volumes of gas at pressures below 0.5 barg need to be cooled or preheated in a large temperature range up to 900°C / 1650°F


Any type of steel plate can be used in a wide range of thicknesses in order to accomodate the required resistance against temperature, corrosion and pressure.


Coated Heat Exchangers

Coating of the heat transfer area is required to operate below the Acid Dew Point.

Coated Solutions

Ecoonex has solutions to coat heat transfer plates and tubes for air preheaters, but also tubes for economizers with raw gas on the outside of the tube and water or oil inside the tube.

Hybrid Solutions

The heat exchangers can be combined with different materials or solutions. Hot part can be made of stainless steel plates where tthe cold part could be with coated tubes or plates.

Operating Below the Acid Dew Point

In order to have more efficient solutions, the cold end solution could be with glass coated plates, or glass coated tubes. Additionally we have solutions to design with Polymer tubes.

Polymer Heat exchangers

The Polymer Heat Exchanger is a state-of-the-art heat transfer device that utilizes advanced polymer materials to efficiently exchange thermal energy between two fluids. Unlike conventional metal heat exchangers, this innovative solution offers numerous advantages.


The polymer construction of the heat exchanger provides exceptional resistance to corrosion, scaling, and fouling, making it highly durable and reliable even in aggressive operating conditions. This eliminates the need for frequent maintenance and extends the lifespan of the exchanger, resulting in significant cost savings for businesses.

Furthermore, the polymer heat exchanger is lightweight and compact, offering greater flexibility in installation and reducing space requirements. Its compact design allows for easy integration into existing systems or the creation of more efficient, space-saving heat transfer setups.

Modular Heat exchangers

Ecoonex is offering modularized heat exchangers that allow clients and end -users to assemble heat exchangers themselvese where the design is made by Ecoonex and the key core components manufactured in our dedicated facilities.


Clients can now add a new product to their portfolio. No design expertice is required as Ecoonex takes care of this. More traditional parts such as casing and return ducts can be made locally with input from Ecoonex, reducing drastically transportation cost and increases scope of the shop where other components are manufactured, Automatically inspection locations are reduced without compromising quality.
