SonFlow SonFlow values


Product range:

SonFlow offers a wide range of gasketed plate heat exchanger that boosts sustainability with an energy-efficient design. Compact frame and innovative plate patterns. 

Suitable for all types of industry and multiple applications from heating, cooling and heat recovery to condensation and evaporation.

We are constantly looking to extend and upgrade the range, adding new performance criteria and greater flexibility.

The design of the corrugated plates optimizes heat transfer by providing a large but compact total surface area through which the heat can be drawn from one liquid or gas to another.

The heat transfer area of the plates is pressed in a corrugated herringbone pattern. Our patterns create the ideal turbulent flow and make the best use of the available pressure drop for any duty.

An optimized flow distribution also reduces fouling and uneven temperature zones keeping the performance levels high over time without unnecessary energy losses, maintenance costs or unplanned stops.

Plates are available with various pressing depths, angles of chevron pattern and various corrugation shapes, all carefully designed and selected to achieve optimal performance - depending on the application, each product range has its own specific plate features.


  • HVAC industry - e.g. district cooling solutions using seawater and groundwater as cooling source - e.g. district heating solutions using, for example, solar and geothermal energy as heating source
