The compact brazed heat exchanger is constructed as a plate package of corrugated channel plates with a filler material between each plate. During the vacuum-brazing process the filler material forms a brazed joint at every contact point between the plates, creating complex channels.
The brazed plate heat exchanger allows media at different temperatures to come into close proximity separated by channel plates that enable heat from one media to be transferred to the other with very high efficiency.
The concept is similar to the older plate and frame technology but without the gaskets and frame parts are simple, flexible, cost effective
The channel plates form separate circuits for each media. The number, type and configuration of the channel plates are easy to vary to provide the thermal characteristics required.
In a one-pass configuration, the two flows are continuous through each channel plate. In a two-pass configuration, the two flows are redirected by special channel plates to give the equivalent of two units connected in series.
In addition to one and two-pass configurations, we offer a variety of other executions and customised solutions.
The flows inside a heat exchanger can be arranged differently to fulfil different purposes. In these brazed plate heat exchanger, counter-current flow is more common because it increases efficiency. These brazed plate heat exchanger also employ co-current flow where necessary in applications such as flooded evaporators.
