AlfaNova
Manufactured with Alfa Laval’s patented AlfaFusion technology, AlfaNova is a heat exchanger consisting of corrugated stainless steel plates bonded together without any copper or nickel. The unique design means that AlfaNova can withstand more extreme temperatures and pressures with greater fatigue resistance than conventional brazed plate heat exchangers. It is also suitable for duties with very high hygiene demands.
More with AlfaNova
- An optimal solution for hygienic applications such as tap water systems
- Copper-free design is suitable for use with ammonia refrigerant and for clean water refrigeration chiller applications
- Load distribution across many contact points secures excellent resistance to pressure fatigue
- AHRI-certified for reliable thermal performance in a range of HVAC applications
- Available with marine classification for use in a range of LPG/LNG duties, due to wide temperature range and copper-free construction
AlfaNova’s unique fusion-bonded manufacturing process provides greater reinforcement for the plate pack, which in turn ensures a higher degree of pressure resistance than that offered by comparable technologies. Additionally, the 100% stainless steel construction makes it possible to withstand temperatures as high as 550°C (1020°F). As a result, the AlfaNova fusion-bonded plate heat exchanger is highly dependable in applications with extreme pressure and/or temperature demands. Use of the same material for all key components also provides high thermal efficiency, in addition to giving the unit mechanical strength equivalent to any fully welded counterpart.
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.
AHRI for HVAC
AlfaNova heat exchangers are available with certification according to the Liquid-to-Liquid Brazed and Fusion-Bonded Heat Exchanger programme of The Air-Conditioning, Heating, and Refrigeration Institute (AHRI). For heat exchangers used in HVAC applications, this programme offers independent, third-party verification of thermal performance according to manufacturers’ published specifications.
How it works
Two media at different temperatures flow on either side of thin corrugated stainless-steel plates that are stacked on top of each other. The two media flow in a countercurrent flow through alternate channels and are held within the plate pack by a fusion-bonded seal around the edge of the plates. The points at which the plates are in contact with each other are also bonded with the same technology, reinforcing the pack against the pressure of the media inside.
The countercurrent flow makes it possible to extract heat efficiently even when there are only extremely small differences between the temperatures of the hot and cold media. This results in notable energy cost savings. In some systems, co-current flows re also possible. The product is optimized for marine applications.

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