TRILLIUM® is a technology that simplifies the complex brazing process by making the degreasing, fl uxing, cleaning, and drying stages redundant. Instead, we make it happen within the material in a process called Active brazing. In 2017, Gränges continued the development of the TRILLIUM® technology and introduced TRILLIUM® Lean, a new multi-layer material with enhanced potential for especially challenging applications. TRILLIUM® Solid, launched in 2010, and TRILLIUM® Lean help customers reduce costs, create new designs, and reach a higher level of profi tability – while reducing their environmental impact.
This technology allows customers to downgauge fin materials and/or apply tougher brazing cycles without compromising quality and performance.
Exhaust gas re-circulation (EGR)
Requirements for lower engine emissions are continuously increasing. Engine exhaust can be extremely corrosive due to its high acid content (sulphur). Gränges is focusing on material validation in this area.
Gränges’ research and innovation efforts have resulted in 52 patent families and 165 patents (as at December 31, 2017).
