Brazed heat exchangers

Product store

We customise our brazed heat exchangers according to your specifications. We offer a choice of copper, CoResist , or stainless steel brazing materials. Our Fishbone and Micro Plate™ plate technologies are available with different corrugations appropriate for any given task. The adaptable design of our brazed heat exchangers makes a variety of connection options possible (including the number of connections, sizes, types, and positions). The optimal amount of plates in a plate pack is determined based on the specifications of the application.

30 years of constant development

The performance and efficiency of the brazed plate heat exchanger have been proven through 30 years of constant development to ensure high thermal efficiency leading to energy savings in air conditioning systems. With its ingenious construction of corrugated plates, the brazed plate heat exchangers offers you one of the most efficient ways to transfer heat from one medium to another.

Fishbone technology

Our brazed heat exchangers based on fishbone technology is a legacy product, and is perfectly suited for applications with high temperatures or pressures. It is also capable of running with fairly visous fluids, due to a larger gap between the plates. Fishbone plates typically has lower pressure drop compared to the MicroPlate™ technology.
