Heat Exchanger Improvements

Typical Aluminium Heat Exchanger

While aluminum-based heat exchangers are quite common in the automotive industry, they have more slowly penetrated other commercial industries.

This resistance to aluminum has largely stemmed from outdated perceptions of its corrosion resistance and thoughts of the superiority of copper for heat exchanger applications due to its higher thermal conductivity.

However, aluminum offers not only important advantages in light weighting and handling, there are a host of fabrication and assembly possibilities.

Alcereco staff have hundreds of years of experience in alloy replacement and have developed a solid, fundamentally-based understanding of what is required to produce an effective aluminum alloy heat exchanger; and the effects of the assembly and processing steps in establishing those criteria. 

This level of understanding starts with knowledge of the effects of different microscopic components and extends to the effects of different production routes.

This allows a significant cost reduction (based on current Al/Cu prices) and lower product weights. This combination leads to lower fabrication costs per unit and lower installation costs due to lower shipping rates per unit.

If conversion of heat exchangers to aluminum isn’t on your agenda, our engineers and scientists can also perform evaluation of existing systems to determine causes of failures or inefficiencies. We can then recommend solutions or process changes to improve your ongoing products.
