GRÄNGES TRILLIUM® ACTIVE BRAZING

Introducing active brazing with TRILLIUM® Lean

Our latest addition to the TRILLIUM® family is TRILLIUM® Lean. Its unique properties enable outstanding brazing results, even in exceptionally challenging product applications. TRILLIUM® Lean is produced through a combined SF/DC production method and allows designable post-braze flux residues of less than 1 g/m2.

TRILLIUM® Solid

With its unique formation of uniform salt and silicon particles, TRILLIUM® has numerous advantages built-in. When launched in 2010, TRILLIUM® Solid represented a major advancement in brazing technology. Produced through spray forming, TRILLIUM® Solid features excellent brazing activity, robustness in sub-optimal atmospheric conditions, and flux residues of less than 4 g/m2.

Together, TRILLIUM® Solid and TRILLIUM® Lean help our customers to reduce costs, create new designs, and achieve better profitability, while reducing their environmental impact.

THE PROCESS

Conventional brazing

Brazing aluminium for heat exchangers usually requires a complex process that includes fluxing, drying, thermal degreasing, and cleaning. Besides consuming time, chemicals, and manpower, the traditional brazing process also generates flux residues that have a negative impact on both the environment, and the performance and quality of the finished product.

Brazing with TRILLIUM®

Brazing with TRILLIUM® means a simplified process and multiple benefits. We call this process ‘active brazing’. As TRILLIUM® has the fluxing agents built-in, several process steps are made redundant, allowing you to braze faster, smoother, better – and in larger amounts. Additionally, TRILLIUM® can be brazed in an atmosphere with less nitrogen and more oxygen compared to a traditional brazing environment, reducing both costs and environmental impact.

ADDED VALUE

CASE RAAL

Customer case: Raal

Multiple benefits, one technology

“The main advantages we have seen with TRILLIUM® technology are reduced labour and production costs,” says Cornelia Cocian, Head of Process Research & Development Laboratory, Raal.“

We also achieve much better fluxing and brazing quality and uniformity, especially in complex structures. Additionally, there are significantly reduced levels of flux residue in the final product, and by eliminating fluxing and drying, we save on energy and chemical costs.”

Designed for challenging applications
In keeping with its strategy of continuous improvement to the production process, Raal has already tested, verified and put into serial production TRILLIUM® Lean. The company has initially used this material on its most challenging applications. “We have successfully introduced TRILLIUM® Lean for the production of plate and bar products, namely large water and oil coolers for the transport industry where exceptionally low flux residues are required,” says Cocian.

“Given the positive results with TRILLIUM® Lean, we are now looking to expand our use of the material, especially for complex cooling structures that are traditionally difficult to flux, as well as completely new application areas.”

Raal is a leading manufacturer of heat exchangers made of aluminium alloys and stainless steel for global brands in the industrial, agricultural, automotive, and construction industries.
