Hydronic Heating Systems by Alfa Laval
The brazed plate heat exchanger is the single most efficient compact
plate type heat exchanger in the market. They are used in a wide
variety of hydronic heating systems in the hydronics industry
ranging from snow-melt of driveways to radiant floor heating, domestic
water heating and several other interesting applications.

How the brazed heat exchanger operates:
The flow pattern of the brazed heat exchanger is similar to any
other plate heat exchanger. The compressed plate pack creates a
continuous series of channels. The plate and porthole arrangements
permit the two heat-transfer media to travel in alternate channels
in a counter flow manner.
The efficiency of these heat exchangers is high due to the turbulent
flow patterns of the fluids through the channels. This allows for
a very close temperature approach of 2-3° F resulting in economic
heat extraction.
 Advantages
of the brazed heat exchanger in hydronic applications:
- They have a high temperature/pressure rating. All Alfa Laval
brazed heat exchangers have a 437° F and 435 psig rating.
- Footprint size of the heat exchanger is small, permitting a
large duty to be done with minimal space
- Brazing creates a strong bond between the plates of the heat
exchanger. This eliminates the need for heavy frames to keep the
plates together resulting in a lightweight unit.
- Complete range of hydronic heat exchangers available in stock
for immediate delivery
- The brazed heat exchanger is a lower cost alternative to the
conventional Shell & Tube heat exchangers due to them being much
more efficient.
