Marine gasketed plate heat exchangers

Alfa Laval has been developing heat transfer technology for more than 80 years and has been active in the marine industry for over a century. Based on that vast wealth of experience, our engineers have designed gasketed plate heat exchangers that set entirely new standards – not only for reliability, but also for thermal performance and ease of service.

marine GPHE

The marine industry’s most modern line of plate heat exchangers

  • Superior reliability and energy efficiency
  • Small size and footprint (CompactFrame™ design)
  • Minimal fouling (CurveFlow™ plate distribution area)
  • Easy installation and service (five-point alignment system)
  • Optimized global supply chain and production for smallest environmental footprint

Suitable for any vessel, Alfa Laval gasketed plate heat exchangers excel in applications from general heating and cooling to heat recovery, condensation and evaporation. With their innovative features, they take reliability to an all-new level and save crews time and effort during maintenance. Above all, their design minimizes fouling and maximizes heat transfer capabilities, which ensures the highest possible energy efficiency.


Gasketed plate heat exchangers for your vessel

Compact, reliable and energy-efficient, Alfa Laval gasketed plate heat exchangers are also safe and simple for crews to maintain. Our flexible marine line provides the right match for your needs today – with the possibility to adjust capacities later.

Heating and cooling in an engine room

On a ship, there are many types of machinery with a cooling demand. When the heat energy cannot be recovered or utilized, the total costs of transferring it away from the machinery should be kept to a minimum. Alfa Laval can ensure a cost-effective central cooling system through our portfolio of innovative plate heat exchangers. Our gasketed plate heat exchangers have unique features that reduce the running costs for engine room cooling – and contribute to sustainability.


Are you on a quest to save energy?

Alfa Laval is setting the standard for thermal efficiency of plate heat exchangers. Bringing together innovative features improving energy efficiency and minimizing downtime we can accelerate the transition to more sustainable solutions and reach net-zero by 2050.

Sådan fungerer det

Varmeoverførselsområdet i en pladevarmeveksler med pakningsmontering består af en række bølgeformede plader, der er samlet mellem en ramme og nogle trykplader for at bevare trykket. Pakninger fungerer som forseglinger mellem pladerne. Væsker løber normalt modstrøms gennem varmeveksleren. Dette giver den mest effektive termiske ydeevne og muliggør en tilgang med nærmeste temperatur, dvs. temperaturforskellen mellem procesmediet ved udløb og mediet ved indløb er mindst mulig.

Features that make the difference

The Industrial line is equipped with features that turn this high-performance family into efficient and reliable workhorses that are easy to service and maintain over the whole product lifecycle.
