Alfa Laval DuroShell is a specially engineered plate-and-shell heat exchanger ideal for demanding duties, such as corrosive, high pressure and high temperature applications. Incorporating many innovative features to optimize customers' process performance, it takes the plate-and-shell concept to a new level. Alfa Laval DuroShell, with its laser-welded plates and many multiple pass and asymmetric flow capabilities, allows optimization of thermal efficiency and substantially improved fatigue resistance. Designed for use with liquids, gases and two-phase mixtures at pressures up to 100barG (1,450 psiG), in both PED and ASME, and at temperatures up to 450 °C (842 °F), Alfa Laval DuroShell is suitable for a wide range of aggressive media. Its capabilities reach far beyond both gasketed and many other welded heat exchanger technologies.
