DuroShell

A heat exchanger to maximize power plant uptime

Heat exchangers play a central role in some of the most fatigue-intensive processes found in power plants. But as you know all too well, some heat exchangers simply aren’t up to the job.

While bulky shell-and-tube heat exchangers have long been the go-to option for demanding applications in power production, more power plants are now considering making the switch to compact plate-and-shells. But just like shell-and-tubes, conventional plate-and-shell designs encounter fatigue problems in positions with extreme changes in temperature and pressure. For many plants, this has already meant a great deal of time and money lost to unplanned downtime.

Alfa Laval DuroShell is a different kind of plate-and-shell heat exchanger, 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.
