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.

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.

PressureSecure
Uovertruffen styrke for krevende oppgaver
Våre innovative platedesign støtter det bredeste spekteret av systemer med høye temperaturer og trykk. Enhetene kan driftes med tynnere plater og færre plater, noe som betyr mindre råvarer, lavere energiforbruk, redusert kjølemiddelvolum og lengre levetid for utstyret.
FlexFlow™
Overlegen termisk ytelse
Alfa Lavals patenterte asymmetriske platedesign er en av mange unike innovasjoner som gir deg bedre termisk effektivitet takket være optimalisert trykkfall og økt turbulens. I tillegg til å redusere energiforbruket betyr det å redusere kjølemiddelvolumer og råvarer.
AlfaNova®
100% stainless steel
Built with 100% stainless steel, AlfaNova® is a solution that Alfa Laval offers for applications that use media not compatible with traditional heat exchanger materials. Not only is this advanced design optimized for use with natural refrigerants, it’s also completely recyclable.
Et brenselcellesystem bygget med Alfa Laval platevarmevekslere – Bærekraftig, trygt og kostnadseffektivt
Da den tyske leverandøren av fornybar energi HEE Technologies GmbH designet et brenselcellesystem for kombinert varme og kraft (CHP), valgte de bevisst å bruke Alfa Lavals platevarmevekslere til kjøling av brenselcellestabler og eksosvarmegjenvinning. Systemet bruker hydrogen som energikilde, noe som gjør det bærekraftig, trygt og kostnadseffektivt.
