More uptime in high-demand petrochemical positions

Heat exchangers are used for some of the most fatigue-intensive processes in petrochemical production. But as you know all too well, some heat exchangers simply aren’t up to the job.

Today, many petrochemical plants have already made the switch to plate-and-shell heat exchangers. Although conventional plate-and-shell designs offer significant advantages over bulky, traditional shell-and-tubes, many encounter fatigue problems in applications with extreme changes in temperature and pressure. In the petrochemical industry, where these applications are common, this translates to time and money lost to unplanned downtime.

Alfa Laval DuroShell is a different kind of plate-and-shell, with a unique internal design that maximizes uptime where you need it the most. The heat exchanger plates have a patented pattern that offers unparalleled fatigue resistance. And for added strength, laser welding is used throughout, ensuring the most accurate weld while minimizing heat stress on the surrounding material.

With the market’s most robust design, switching to DuroShell means greater reliability for your plant’s most demanding duties. That’s why we call it plate-and-shell made tougher.
