With higher heat transfer efficiency and optimisation, these heat exchangers offer the most efficient thermal performance.
We have one of the largest plate portfolios in the world and we customise each heat exchanger to meet your exact requirements. The versatile design and high thermal efficiency make them the perfect solution for a wide range of applications, including the transfer of heat across a diverse temperature difference.
Features and benefits
Experience the benefit of an individually customised solution that perfectly matches your requirements and lowers your energy consumption, thus improving energy efficiency. Our heat transfer solutions ensure that there are no stagnant zones and create high flow turbulence for optimal results.
High performance for a low pressure drop eliminates unnecessary burdens on your system and optimises overall system performance.
We design single-pass solutions when possible, as they are the preferred choice for almost all duties. With all connections on the head you do not need to disconnect the heat exchanger from the piping to perform inspection, cleaning, or service.
Gasketed plate heat exchangers are uniquely designed with specific plate features, including frame and pressure plates. These special features ensure the entire heat transfer surface is utilised, thereby enhancing the heat exchanger performance. thus improving energy efficiency. Our heat transfer solutions ensure that there are no stagnant zones and create high flow turbulence for optimal results. The design results in a compact solution with a small footprint, simple installation, and easy access for maintenance.

D-plate technology
Our Danfoss engineers have enhanced the way heat exchanger plates are designed with the introduction of the new D-plate series. With various pressing depths and corrugated plates, the media flow in an opposite direction in alternate channels between the plates. This results in transferring heat effectively. Drawing on years of experience within heat transfer technology and deep application knowledge, we have made significant upgrades to the traditional Fishbone plates to truly redefine the way we think of heat exchanger plates.
SONDEX® Fishbone plates
SONDEX® Fishbone plate pattern technology is used for the vast majority of our plate heat exchangers. The pattern is designed for high thermal performance while using the allowed pressure drop in the most efficient manner. Available with different pressing depths, pattern pitch and angles – each plate has a pattern that is optimised for a certain duty. These heat sensitive plates provide optimal performance and guarantee efficient heat transfer area across a full range of applications.
Our product range includes small to large heat exchangers suitable for all types of industries. For instance, heat transfer solutions like our SONDEX® condensers and evaporators are designed for advanced duties. They accommodate high flow rates and work under diverse system pressures and temperatures.
At Danfoss, we believe that every heating or cooling challenge can be met with innovative heat exchanger solutions. Whether it's hot water production in domestic hot water systems or handling aggressive, corrosive fluids in the chemical industry, we have a solution in our vast product range.
