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 til krævende opgaver
Vores innovative pladedesign understøtter stort set alle anlæg, der fungerer med høj temperatur og højt tryk. Enheder kan køre ved hjælp af tyndere og færre plader, hvilket betyder mindre forbrug af råmaterialer, lavere energiforbrug, reduceret kølemiddelpåfyldning og længere levetid for udstyret.
FlexFlow™
Overlegen varmeevne
Alfa Lavals patenterede asymmetriske pladeudformning er en af mange unikke innovationer, der giver bedre varmeffektivitet i kraft af optimeret trykfald og øget turbulens. Ud over at sænke energiforbruget betyder det, at forbruget af kølemidler og råmaterialer også kan reduceres.
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 brændselscellesystem bygget med Alfa Laval-pladevarmevekslere – bæredygtigt, sikkert og omkostningseffektivt
Da den tyske leverandør af vedvarende energi, HEE Technologies GmbH, designede CHP-brændselscellesystemet (kombineret varme og energi), var det et klart valg at bruge Alfa Lavals pladevarmevekslere til brændselscelle-stabelkøling og udstødningsvarmegenvinding. Systemet bruger brint som energikilde, hvilket gør det bæredygtigt, sikkert og omkostningseffektivt.
