Constellium has developed KOOL X® range for demanding applications in automotive heat exchangers such as charge air coolers, and evaporators. The charge air coolers work to cool down exhaust gas to be recycled inside the vehicle. Generally situated very close to the motor, they require higher corrosion resistance than other types of heat exchangers. Constellium's new multi-layers KOOL X® solutions have been developed to address these specific needs. The addition of one or several layers to the traditional 3 layer cladding solution ensure exceptional corrosion resistance while retaining required brazeability.
