Why DuroShell?

Regulating temperatures quickly and accurately is critical to both product quality and process yield in petrochemical production. But few heat exchange solutions have been able to offer the high efficiency and performance reliability that these demanding operations require. Alfa Laval DuroShell is different. With a robust design, high thermal transfer rate and low hold-up volume, it can secure reliable and cost-effective production in a variety of petrochemical applications.

As flexible as it is strong

Compact and exceptionally resistant to fatigue, DuroShell creates new possibilities through its unique strength and efficiency. Able to work with liquids, gases and two-phase mixtures, including a wide range of aggressive media, it stands out among heat exchangers in its duty range. DuroShell handles pressures up to 100 barg (1450 psig) in compliance with PED and ASME, along with temperatures as high as 450°C (842°F).

Built for your application

DuroShell is fully welded and gasket-free, with internal features that make it still more robust. Plates are available in 316L stainless steel or titanium, while the pressure vessel itself can be built in 316L stainless steel or carbon steel. Three different sizes are possible, with heat transfer surfaces ranging 2–235 m2 (21.5–2530 ft2) in area.
