Gränges’ clear focus on serving the global heat exchanger industry with leading products and solutions has made the company into a trusted and long-term partner. The addition of Noranda downstream creates opportunities to develop new solutions in close co-operation with the customers.
Over the years, Gränges has developed a large number of products with improved end-characteristics, increased stability and enhanced sustainability. Many of these products are based on new concepts such as SSR fin and TRILLIUM®. Gränges’ focus on technology, manufacturing processes, and material properties contribute to creating smaller, lighter and better designed heat exchangers that are more energy efficient and reduce environmental impact. Through the acquisition of Noranda downstream, Gränges now also offers rolled aluminium products to manufacturers of automotive heat shields, transformer windings and semirigid containers.
Added value for the customer
Gränges offers a comprehensive range of clad and unclad rolled aluminium products used for brazed heat exchangers for applications with a high degree of functionality and performance. Depending on the specific needs of a given application, Gränges offers multi-layer products with up to five layers. This variety provides virtually unlimited possibilities for customised solutions based on carefully selected alloy combinations, delivery conditions, plating thickness and geometries.
Stationary heat exchangers
Gränges focuses on driving technological change through stationary heat exchangers (HVAC), from mechanically bonded copper tubes to brazed aluminium heat exchangers, just as was the case in the automotive industry where Gränges’ solutions have played a key role in the conversion from conventional to contemporary systems. Focus is concentrated on products that contribute to improved energy efficiency and reduced environmental impact. Gränges is also able to deliver prototypes that customers are able to test at their own applications. This enables the development of even stronger, lighter, and more corrosion resistant condensers with greater efficiency and reduced overall environmental impact. With its acquisition in the US, Gränges has also obtained a broader offering of products and solutions that also meet other needs within the stationary HVAC industry.
Heat exchangers for industrial applications
The next step is to develop solutions for industrial applications, such as wind power turbines and agricultural machinery, which have a market footprint that is four times the size of HVAC.
There are up to 3,000 product speciﬁcations, including 200 combinations of alloys, that Gränges offers to its heat exchanger customers. The products can be divided into four main groups:
