Fusion-bonded plate heat exchangers

Alfa Laval’s patented AlfaFusion bonding technology creates highly efficient, compact heat exchangers made entirely of stainless steel. Virtually maintenance free and capable of handling extremely high pressures and temperatures, they are an ideal heat transfer solution for challenging applications. These include duties with high cleanliness demands, with aggressive media such as ammonia, or where copper or nickel pose contamination risks.

Sustainable Heat Transfer

  • 100% stainless steel construction means 100% recyclability
  • Resists corrosion from aggressive media and process fluids
  • Prevents nickel or copper-contamination when working with drinking water or any other hygienic fluid
  • AlfaFusion technology enables higher temperature resistance than traditional brazed heat exchangers with same high-pressure capabilities
  • Optimized plate design with asymmetric channel configuration provides maximum efficiency in demanding heating and cooling applications
AlfaFusion is a breakthrough manufacturing technique that combines improved hygiene and corrosion resistance with the high efficiency and compact footprint of a brazed plate heat exchanger. By enabling a full stainless steel construction, our fusion-bonded AlfaNova heat exchangers can be used in installations normally reserved for conventional semi-welded and welded technologies. They are also a confident choice when the prime focus is on cleanliness, such as in clean water refrigeration and tap water heating systems.

Meet the new AlfaNova GL50

The GL50 is an asymmetric gas-to-liquid plate heat exchanger made from 100% stainless steel. It is small enough to hold in one hand, but can handle gas flows of 250 cubic meter per hour, as well as inlet gas temperatures up to 750°C, with exceptional performance.


AlfaNovaTW® 66: the latest in 100% stainless steel innovation

You can’t compromise. So we don’t either. For minimizing metal contamination in tap water duties, no stainless steel heat exchanger gives you more confidence than Alfa Laval’s AlfaNovaTW. With the launch of the larger capacity AlfaNovaTW 66, this range offers solutions for domestic water installations big and small, as well as a wide scope of other HVAC heating and cooling applications.

A fuel cell system built with Alfa Laval's stainless steel plate heat exchangers - Sustainable, safe and cost efficient

When the German renewable energy supplier HEE Technologies GmbH designed a combined heat and power (CHP) fuel cell system, it was a clear choice to use Alfa Laval’s stainless steel plate heat exchangers for fuel cell stack cooling and exhaust heat recovery. The system uses hydrogen as an energy source, making it sustainable, safe, and cost efficient.

When nickel and copper just won’t do

In applications with high hygiene demands, all equipment must conform to the strictest standards. For drinking water applications in particular, where protecting consumer health is a top concern, preventing the possibility of nickel and copper contamination has become a critical issue. As a result, more and more OEMs are seeking heat exchanger solutions for clean water chillers and tap water heating systems that do not use these metals.

Built in 100% stainless steel, AlfaNova heat exchangers are an optimal choice when nickel and copper just won’t do. In addition to providing peace of mind when it comes to hygiene, they also offer much higher efficiency than traditional copper and nickel-free solutions used for these duties.
