Anodized aluminum is a process that enhances the durability and resistance of aluminum by creating a protective oxide layer on its surface. This layer not only prevents corrosion and wear but also allows for custom surface coloration. Here are some key points about blue anodized aluminum: Color Options: Aluminum can accept a wide spectrum of anodized colors, including blue. Other available colors include pink, black, silver, gold, green, orange, red, and purple.Anodization serves multiple purposes: Corrosion Resistance: The protective oxide layer acts as a barrier against corrosion. Aesthetics: Anodized aluminum looks sleek and reflective due to the uniform oxide layer. Scratch Resistance: The tough anodic finish increases scratch resistance. Other Qualities: Anodization also affects wear resistance, heat dissipation, and adhesion. blue anodized aluminum combines aesthetics with functionality, making it a popular choice for various applications.

Our company has been manufacturing finned coil heat exchangers for over 40 years. The design of each finned pack can be totally developed inhouse by Stefani or taken from a drawing supplied by our customer. This is possible thanks to a strategic coengineering service, which is necessary especially when developing specific designs. In the design and manufacture of our finned coil heat exchangers we put all the flexibility and competence that have always been the hallmark of our work. We make customised finned packs for production in batches, dedicated to the machines of our OEM customers and, in general, to data centres, air treatment units for industrial refrigeration, industrial and commercial air conditions and condensing units for refrigeration.
