compact brazed heat exchangers - IN

A STEP TOWARDS A MORE
EFFICIENT REFRIGERANT INDUSTRY
Simulation is one of the most important stages in
the development of new and existing CBEs. The
ability to evaluate different plate patterns by
simulating flow rate and directions offers great
opportunities for improved functionality.
SWEP is a rapidly growing international company in the
heat transfer field. Decades of creative work, leadingedge competence and committed SWEP people have
resulted in the world's most effective offer of products.
World-leading within its field, SWEP constantly
advances the front line in order to be able to use the very
latest technology. SWEP's aim is constantly to offer its
customers excellent performance, economy and service.
Today, SWEP is close to its customers, with representation in more than 50 countries and its own
dedicated salesforce in more than 20 countries. With
highly efficient production units in Sweden, Switzerland,
USA and Malaysia it is possible to serve customers all

Each SWEP CBE is delivered with full traceability
and verified functionality. A SWEP CBE is
approved by leading independent international
bodies, such as PED, UL, KHK and CSA.

Air dryers, chillers, cascade heat
pumps and refrigeration systems are
typical examples of applications that
operate more efficiently using
compact brazed heat exchangers
(CBEs). The list of new applications
is growing continuously, and today
you will find SWEP CBEs in virtually
all kinds/sorts of applications in the
global refrigerant market. Alongside
the increase in the areas of use,
there is also a rapid technological
changeover to modern high-efficiency SWEP CBEs where shelland-tubes were previously used.
Extensive research and development combined with effective use of
CFD (Computational Fluid Dynamics) have enabled us to offer the
market's most comprehensive range
of condensers, desuperheaters,
evaporators and subcoolers for all
types of refrigerant applications.
And by using standardized components, we can cost-effectively mass
customize the product precisely to
your needs.
We can always offer you more,
thanks to our complete program of
effective aids. SSP, the SWEP
Software package that we have
developed for dimensioning exchangers and dynamic drawing
generation, is the soft way to get
hard facts. Or why not do some indepth reading in our Refrigerant
Handbook, the complete handbook
for CBE refrigerant applications?

transfer consultants today to find out

In principle, a CBE is constructed
as a plate package of corrugated
channel plates between front and
rear cover-plate packages. The
cover plate packages consist of
sealing plates, blind rings and cover
plates. During the vacuum-brazing
process, a brazed joint is formed at
every contact point between the
base and the filler material.

The fluids can pass through the heat
exchanger in different ways. For parallel flow CBEs, there are two different flow configurations: co-current or counter-current.
