High-Efficiency Energy Recovery Systems
Our finned pack heat exchangers for energy recovery systems are designed to ensure maximum heat exchange efficiency, thanks to a special circuit configuration that guarantees true counterflow operation.
This design maximizes the logarithmic ΔT between the two fluids and achieves performance levels unattainable with traditional cross-flow solutions.
The system is fully ventable and drainable, allowing for reduced installation and maintenance times.
It is the ideal solution for Air Handling Units (AHUs) that must comply with European energy efficiency requirements and ErP directives.

Guaranteed performance
Our energy recovery systems achieve 68% efficiency according to EN 308, regardless of the number of rows or geometry used.
This performance is made possible by advanced circuit design, optimized flow distribution, and dedicated fin profiles.
Compliance with European ErP Directive (Energy Related Products)
Performance validated through internal experimental tests
Possibility of joint validation and comparative testing with the client
Reduced air-side pressure drop thanks to dedicated fin profiles
Higher efficiency compared to traditional cross-flow configurations
The images show the heat transfer by individual rows in counterflow as a function of the temperature difference between the two fluids. On the left, flow and temperatures are optimized, achieving 68% efficiency with 14 rows. On the right, a non-optimal situation requires double the surface area for the same process.
