What are the benefits of using aluminium?
Hydro Aluminium Precision Tubing: Aluminium offers numerous benefits for the HVACR industry in terms of cost savings as well as technical improvement potential. Mainly, we can say weight, performance gain in heat exchange applications and high formability. For more details, click on “Why aluminium in HVACR?”
Will I save money by using aluminium in my whole process?
Hydro Aluminium Precision Tubing: By switching from copper to aluminium, you will get more meters of aluminium tubes for the same price for use in your HVACR products. There will be some costs related to process changes and the training of brazing personnel, but there is no doubt that cost savings will be achievable once production has been implemented. Over the long term, the recycling costs of an all-aluminium heat exchanger will also become cheaper than for a product consisting of different metals, which makes the all-aluminium solution even more competitive.
What are the performance gains from all-aluminium heat exchangers, both mechanically expanded and brazed?
Hydro Aluminium Precision Tubing: The performance in heat exchangers with round tubes is comparable to the performance of heat exchangers based on copper tubes. Using aluminium microchannels as tube material, however, offers performance increases of up to 30 percent due to the geometrical characteristics of these tubes. Further, the ratio between inner volumes and outer surfaces of the microchannel tubes also opens for heat exchanger designs with smaller amounts of refrigerants.
