The Alfa Laval brazed heat exchanger
The Alfa Laval BHE is the original brazed plate heat exchanger. The BHE concept
is a variation of the traditional plate and frame heat exchanger, but without gaskets
and frame parts. The BHE simply consists of channel plates, two cover plates and
connections. All including parts are made of stainless steel material.

brazing material seals as well as holds

the plates together at the contact points.
Alfa Lavals brazed heat exchangers are
always brazed at all contact points,
which ensures optimal heat transfer
efficiency and pressure resistance. The
plates are designed to achieve longest
possible lifetime.

Since virtually all material is used for heat

transfer the BHE is very compact in size
and has a low weight and a low hold-up
volume. Alfa Laval offers a flexible design
that can be customised to meet the
customers specific requirements. The
brazed plate heat exchangers from Alfa
Laval ensure the customer the most
cost-efficient solution to his heat transfer
duties.

 Applications

Applications
Brazed plate heat exchangers are com-
monly used in all types of heating
applications with demands on comfort,
reliability and safety. Heating, in most
cases, is a matter of providing a com-
fortable indoor environment, whether at
home, at work or in a public facility.
It can also involve heating tap water,
swimming pools, greenhouses etc.

Heating and District Heating

General heating applications are often
divided into heating and district heating,
based on several major differences.
Heating systems normally have the heat

normally provided from a boiler, but
it can also come from heat pumps
and solar panels. In contrast, district
heating systems distribute hot water
or steam to multiple buildings. The
heat can be provided from a variety
of sources, including geothermal sourc-
es, co-generation plants, waste heat
from industry, and purpose-built heating
plants. Whether it is heating or district
heating, the BHE has its natural place
in the system.

Tap water heating

The advantages of using a brazed plate
heat exchanger to produce hot tap
water compared to traditional coil
in tank systems are numerous. The
BHE instantly heats the tap water to
the required temperature when it pass-
es through the heat exchanger. This
means that hot water is available imme- The small hold up volume means that the tap

instant hot water.
with using plate heat exchangers for
hot tap water production is that the
system requires much less spaces than
a traditional tank and coil system. If
solar energy is used to produce hot
tap water a BHE makes it possible to
separate the treated water in the solar
panels from the tap water circuit. Also,
scaling problems and corrosion risks in
the solar panels are reduced when sep-
arating the circuits with a BHE.

Accessories

Cleaning-In-Place (CIP)
All types of heat exchangers need to
be cleaned regularly to remove deposits
such as scale, sludge and microorgan-
isms. Alfa-CIP is a convenient solution
that carefully removes the deposit on
all heat transfer surfaces in the heat
exchanger. Alfa-CIP 75, 200 and 400
are constructed in stainless steel using
high quality components (pumps, valves
etc.) according to ISO 9001 and with
the CE-mark. The smaller units Alfa-CIP
20 and 40 are made of industrial grade
plastic. Alfa-CIP is mobile due to its
compact design. The units have revers-
ible flow, and Alfa-CIP 75, 200 and 400
also have a built in heater. All cleaning
detergents used by Alfa Laval are envi-
ronmentally friendly and do not damage
the equipment.

Couplings for welding or soldering

The couplings fits on the threaded con-
nections of the units. Future service is
then easy made by dismantling the heat
exchanger from the pipes via the cou-
plings. This connection is approved in
most countries when weld or flange
connection is required. A flat washer is
used as sealing between the coupling
and connections.

Therefore fast closing valves should
not be used unless the pipes in the sys-
tem are very short. Any problems with
keeping the performance of the heat
exchanger may be caused by changing
temperature conditions, changing flow
rates or by fouling.

Maintenance instructions
The heat transfer through the plates can
be seriously reduced by the formation
of deposits of various kinds on the plate
surfaces. Even if the highly turbulent
flow gives a strong resistance to the for-
mation of deposits the turbulence can
not completely eliminate fouling. Thanks
to CIP (Cleaning In Place) it is possible
to remove calcium deposits and other
forms of scaling from the plate surfaces
in an easy and effective way. Different
cleaning solutions can be used depend-
ing on the type of deposits. Alfa Laval
has a world-wide service organisation.
Service is available in 130 countries at
15 major service centres and a network
of service stations around the globe.
