Brazed Plate Heat Exchanger
General information
Alfa Laval introduced its first 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 efficiency 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 specifications. You can choose a
standard configuration BHE, or a unit designed according to
your own specific needs. The choice is entirely yours.
Liquid/liquid applications:
- HVAC heating/cooling
- Process heating/cooling
- Hydraulic oil cooling
- 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
flow through alternate channels, usually in countercurrent flow
for the most efficient 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.
