 Alfa
Laval's AlfaNova Series
AlfaNova is a completely new type of plate heat exchanger,
the world’s first Plate Heat Exchanger made of 100% stainless
steel. It is based on Alfa Laval’s new revolutionary technology,
AlfaFusion, the art of joining stainless steel components together.

AlfaNova heat exchangers are well suited in applications which
put a high demand on cleanliness, where Ammonia is used or where
copper or nickel contamination cannot be accepted.
Comparing different plate heat exchangers
Different types of plate heat exchangers were tested to compare
pressure fatigue resistance and thermal fatigue resistance.
Fusion Bonded Plate Heat Exchangers for the Process Industry
 100%
Muscle
Aggressive media, high temperatures and pressures are everyday
conditions for heat exchangers in industrial processes.
Extreme conditions demand extreme technology. Produced by the patented
AlfaFusion bonding process, AlfaNova™ is the world’s first 100%
stainless steel plate heat exchanger.
With its high mechanical strength and no gaskets, the compact AlfaNova
is the obvious choice for tough applications in the process industries.
It can handle aggressive media and temperatures from –196°C up to
550°C (–320.8°F up to 1022°F), and is capable of working with approach
temperatures down to 1–2°C.
AlfaNova will save money in your plant by ensuring maximum heat
recovery from your process, thus reducing the amount of heating
and/or cooling media required.
 High
Performance, superior strength, compact design.
Manufactured in 100% stainless steel, AlfaNova is a high-performance,
cost-efficient plate heat exchanger designed to handle demanding
duties in a broad spectrum of industrial applications and utilities.
It is available in a wide range of sizes.
Patented by Alfa Laval, AlfaFusion is a one-material process where
Alloy 316 stainless steel corrugated plates are bon ded in a high
temperature furnace using stainless steel filler as the activator.
The muscle you need in a compact package AlfaNova offers an unmatched
ratio of price to performance and performance to size. The unique
pattern of the corru gated plates provides optimum heat transfer
with approach temperatures down to 1–2°C and low hold-up volumes.
Superior mechanical strength
AlfaNova’s 100% stainless steel and gasket-free design ensures high
mechanical strength. AlfaNova can withstand temperatures from –196°C
up to 550°C (–320.8°F up to 1022°F), and pressures up to 30 bar.
Simple to maintain
AlfaNova is a sealed unit. Due to its small hold-up volume, compared
to a shell-and-tube unit, it is easily cleaned by flushing, using
an Alfa Laval Cleaning-in-Place (CIP) system. The time-consuming
task of opening a shell-and-tube heat exchanger is thus avoided.
Just hook up and switch on.
Cleaning with a CIP unit is a cost effective way to achieve better
performance. The environmentally friendly clean ing agents used
extend AlfaNova’s opera ting time between cleaning cyc les, pro
longing the lifetime of the heat ex changer, without damaging the
plates.
 It's
often possible to replace large, heavy heat exchangers.
Replace your large shell-and-tube heat exchanger with an AlfaNova
heat exchanger. It will save you money by ensuring maximum heat
recovery from your industrial process, while reducing the amount
of cooling and heating media required.
Much more compact than shell-and-tube units The compact AlfaNova
occupies much less floor space than a comparable shell-and-tube
heat exchanger. Shell- and-tube units are big, bulky and much less
efficient.
The corrugated stainless steel plates in AlfaNova ensure high turbulence.
This reduces fouling and results in up to five times higher heat
transfer co efficient than a comparable shell-and-tube unit, and
thus a lower investment cost.
AlfaNova is capable of handling crossing temperatures, and has
80–90% less hold-up volume than a shell-andtube heat exchanger,
ensuring a quick response.
Shell-and-tube units require frequent, labour intensive maintenance,
while AlfaNova can easily be cleaned in place.
When to choose AlfaNova
For a wide range of duties, AlfaNova is the best, most cost-efficient
solution on the market today. When your application demands a gasket-free
solution, depending on media or temperature, AlfaNova is often the
best choice. Possessing similar characteristics to Alfa Laval all-welded
plate heat exchangers, AlfaNova is the perfect complement to Alfa
Laval’s heat exchanger portfolio.

AlfaNova Applications
AlfaNova heat exchangers are ideal for many different applications.
The gasket-free solution makes it possible to use AlfaNova in an
organic solvent/ solvent interchanger where the medium is too aggressive
for gaskets. It can also be used as a heater or cooler when the
temperature is too high or too low for gaskets. Additionally, AlfaNova
can be used as a gas heater, gas cooler, condenser or reboiler.
