General information
Alfa Laval introduced its rst brazed plate heat exchanger
(BHE) in 1977 and has since continuously developed and
optimized its performance and reliability.
Brazing the stainless steel plates together eliminates the
need for gaskets and thick frame plates. The brazing
material seals and holds the plates together at the
contact points ensuring optimal heat transfer efciency
and pressure resistance. The plate design guarantees the
longest possible life.
The design options of the brazed heat exchanger are
extensive. Different plate patterns are available for various
duties and performance specications. You can choose a
standard conguration BHE, or a unit designed according
to your own specic needs. The choice is entirely yours.
Typical applications
• HVAC heating/cooling
• Refrigerant applications
• Industrial cooling/heating
• Oil cooling
Working principles
The heating surface consists of thin corrugated metal
plates stacked on top of each other. Channels are formed
between the plates and corner ports are arranged so that
the two media ow through alternate channels, usually
in countercurrent ow for the most efcient heat transfer
process.
Standard design
The plate pack is covered by cover plates. Connections
are located in the front or rear cover plate. To improve the
heat transfer design, the channel plates are corrugated.
