My name is Frederic Rondet and I am a Concept Development engineer with Alfa Laval. I work with a team that develops new features for our products including those found in our DuroShell plate-and-shell heat exchangers. A key feature of DuroShell is our unique RollerCoaster™ plate pattern which helps customers achieve increased thermal efficiency, reliability and sustainability in their processes. Unlike the simple chevron pattern used in conventional plate-and-shell designs we engineered RollerCoaster™ to optimize fluid distribution over the whole plate. It uses every square millimetre of the plate – even the areas behind the ports – to provide more effective heat transfer. By giving a more even flow across the plate, RollerCoaster™ reduces pressure drop and eliminates hot spots that could result in scaling or loss of performance. That means less service time for cleaning. Traditional chevron patterns are also prone to fatigue failure under aggressive high-pressure or high-temperature cycles. RollerCoaster™ is mechanically much stronger. The symmetric design with uniform temperature distribution induces less stress, giving DuroShell greater fatigue resistance in the most demanding duties. Thanks to patented solutions like RollerCoaster™, DuroShell means more efficient heat transfer with less risk of unplanned downtime. That’s one more reason why we call it plate-and-shell made tougher!
