Our SONDEX® standard plate heat exchangers are the ideal choice for a wide range of applications across numerous market segments. Innovative technologies and smart design make our standard plate heat exchangers a stellar investment and the go-to choice for standard duties.
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.
Features and benefits
Experience the benefit of an individually customised solution that perfectly matches your requirements and lowers your energy consumption.
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.
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. 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.

Our SONDEX® condensers are the perfect choice for special applications that regular plate heat exchangers cannot handle. Designed to accommodate high-volume vapor flows, this product features a large inlet for the vapor stream. Combined with a short residence time, the optimal condensation conditions are created – even for low-pressure vapor duties.
