Danfoss has introduced the D353 gasketed plate heat exchanger - the latest addition to its extensive plate heat exchanger portfolio.
Developed with data centres in mind, the D353 is designed for applications where uptime, heat transfer efficiency, and ease of maintenance are essential.
Its compact frame design can reduce both height and footprint, supporting easier installation in facilities where every square meter matters.
The D353 builds on proven Danfoss heat exchanger technology while introducing design features that make service faster and less complex.
The D-Lock gasket system, improved plate alignment, ArcCompact plate suspension, and internal roller system support easier handling, maintenance, and resealing — helping customers reduce service complexity in critical cooling systems.
Beyond data centres, the D353 also opens new opportunities in other demanding applications, including AI infrastructure, offshore applications, and geothermal systems. With support for higher operating pressures the D353 gives customers greater flexibility to adapt the solution to different system requirements.
With the introduction of the D353, Danfoss continues to strengthen its gasketed plate heat exchanger offering - helping customers improve cooling performance, simplify service, and build more resilient systems for the future.
