Permanently Sealed Brazed Heat Exchangers

SonFlow’s new efficient brazed heat exchangers (SFB) are permanently sealed heat exchangers suitable for a wide variety of applications across numerous market segments.


For the brazed heat exchanger series, the key focus lies in reliability and high performance. Our talented team with more than 40 years of experience in heat exchangers has developed and thoroughly tested the efficient brazed heat exchangers, handling advanced heat transfer technology.



Every detail is carefully designed to ensure optimal performance, reduce maintenance costs, and decrease downtime.
One of our focus areas is sustainability and therefore it is important that the units are energy-efficient and environmentally friendly.


The Brazed heat exchanger is constructed by a package of thin corrugated metal plates, surrounded by two thicker stabilizing plates. A thin copper foil placed between each of the thin metal plates melts and seals the brazed plate heat exchanger during a vacuum brazing process.


We calculate each solution based on the customer’s requirements to ensure an ideal pressure drop and flow rate. And at the same time, the unit becomes energy-efficient and environmentally friendly. Based on the individual task, we also determine the number of plates and the size of the brazed heat exchangers.



The design of the corrugated plates optimizes heat transfer by providing a large but compact total surface area whereby the heat can be drawn from one liquid or gas to another.
The plates are optimised to meet specific temperature demands and capacities.


Designed to meet your needs

Our extensive range ensures that we can offer the best solution at the best price and, if required, combine several different types of heat exchangers to ensure that you get the best possible solution.
