Our brazed plate heat exchangers (XB/SL) offer a compact and flexible solution designed for ultra-efficient performance for your high-pressure or extreme-temperature applications.

What does that mean for you?

Low operational costs and very high performance make the gasket-free brazed plate heat exchangers optimal choices, even if your system has large temperature swings, or varying or constant pressure.

We have consolidated the Danfoss and SONDEX® brazed solutions into a single, combined plate heat exchanger portfolio. Through our new, second-to-none product range we can offer you complete coverage with quality heat exchangers that are optimized for each individual application.

We customize our brazed heat exchangers according to your specifications. We offer a choice of copper, copper+, or stainless steel brazing materials. Our Fishbone and Micro Plate™ patterns 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, their sizes, types, and positions). The optimal amount of plates in a plate pack is determined based on the specifications of the application.

Ultimate leakage protection

Our Sonder Safe technology is a double-walled plate system designed to make any leakage however unlikely, visible from outside the heat exchanger. This safety measure, available in industrial or sanitary versions, ensures that the malfunctioning unit can quickly be identified and replaced.

Because all leaks are external instead of internal the media are always separated. This makes double-walled brazed plate heat exchangers the ideal solution when operating with media that must not be allowed to mix at any cost.

Fishbone plate technology

Engineered to maximize turbulence, even at low flow rates, this pattern achieves unparalleled heat transfer. The pattern has proved its effectiveness through rigorous testing and is the default choice for plate heat exchangers.

Low operational costs, small hold-up volume, and high performance make our brazed heat exchanger solutions the ideal choice for many applications. Cut your costs and increase your profits with the help of our brazed portfolio.

The permanently sealed heat exchangers offer a durable solution with an extended lifetime. Enjoy peace of mind with the double-walled design that provides the ultimate protection against leaks.

With the energy-optimized, tried-and-true Fishbone technology, or the revolutionary Micro Plate™ technology; the combined Danfoss and SONDEX® product range offers the ultimate in brazed heat transfer solutions.
