Experience a new standard of reliability

Regardless of the industry or application, it goes without saying that you need a heat exchanger that is dependable. A broken or malfunctioning unit can waste time, hurt productivity and compromise safety – which ultimately cuts into your bottom line. That is why we have aimed to increase the reliability of our gasketed plate heat exchangers in all aspects. We focus on durable designs based on robust materials and safe manufacturing processes. And in combination with advanced and innovative product features, you can be totally confident in your unit’s operation.


The SteerLock™ plate alignment ensures reliable plate positioning and easy service. It also secures the plate pack when exposed to pressure and temperature during operation. If the unit is disassembled for maintenance, the smart design simplifies the picking of plates when they are about to be hung back.

Five-point alignment

Alfa Laval’s unique five-point alignment system ensures perfect plate alignment when closing the unit, while simultaneously making it quick and easy to remove plates during maintenance. Excellent plate positioning secures reliable mechanical performance and helps extend the life of your equipment.

The RefTight™ sealing system enables enhanced, long-term performance in applications with high pressures and temperatures. The weld is positioned outside the separate ring gasket groove, ensuring reliable sealing as well as extended gasket lifetime and prolonged service intervals.

The PowerArc™ plate pattern divider is a feature in the bigger plates of Alfa Laval’s next-generation heat exchangers. This design ensures a more rigid plate, preventing plate elongation and securing perfect alignment. As a result, the risk for leaks or damage to the plate is significantly reduced, meaning you can expect longer operation from every plate in the pack. Additionally, the increased rigidity makes handling plates during maintenance a safer and easier process.

Single-step pressing

Single-step pressing

When producing plates for our heat exchangers, Alfa Laval’s standard process involves the use of a single step with a large press. Other suppliers more commonly employ a multi-step approach with a smaller press. While this saves money for the manufacturer, it can lead to uneven plate thickness and zones of unpressed material where fatigue-related cracks can easily occur once the heat exchanger is in operation. Our single-step pressing method prevents these stress faults and provides uniform thickness across the entire plate. This secures increased strength for reliable, long-term plate performance.
