Our traditional, semi-welded, and brazed plate heat exchangers are outstanding choices for standard evaporation duties.
However, certain applications prove unsuitable for regular heat exchanger types. In the interest of guaranteeing unsurpassed product quality, we have created exclusive evaporator plates tailored to meet the challenges presented by advanced evaporation applications.
What does that mean for you?
We are dedicated to making sure that your product quality is first-rate. Our distinctive evaporator plates are made for applications that involve temperature-sensitive or delicate media and excel at multi-stage evaporation of highly concentrated products.
SONDEX® rising film plate evaporators gently treat the media, even if they are highly viscous, and provide uniform evaporation, leading to improved concentrate quality.
Experience first-hand the benefit of our remarkable inlets that eliminate stagnant zones, and evenly distribute the media across the entire heat transmission area for flawless evaporation.
Our special evaporator plates use a Free Flow pattern to create the ideal turbulent flow and reduce the risk of fouling considerably. By doing so, we extend the intervals between cleaning and maximize the uptime of your installation.
Perfect evaporation conditions
The low hold-up volume of SONDEX® evaporators shortens the residence time and provides the best evaporation conditions for temperature-sensitive products.
Operating with low hold-up volumes enables fast start-up and shut down, with only minimal waste, which adds to the overall flexibility of your system and process.
Micro plate technology
Our heat exchangers with the new state-of-the art Micro Plate™ technology feature next-generation efficiency and performance – giving you more from your district heating and cooling applications.
SONDEX® Free flow patterns
The SONDEX® Free Flow pattern is designed to treat media that is unsuitable for regular heat exchangers due to high viscosity, fiber and particle contents, or considerable risk of fouling.

- Plate materials: AISI 304/316, titanium, SMO, Hastelloy. Other materials available upon request
Features and benefits
Special plate design featuring an extra-large inlet connection for steam. Steam consumption can be reduced when operating with multi-stage evaporators, as the product vapor will serve as the heating media.
Flexible design that makes it easy to increase capacity by adding additional cassettes or decrease it to save energy. Low residence time leads to perfect evaporation conditions and superior product quality.
High performance, even with low temperature differences between the media, which is especially great for mechanical vapor recompression (MVR) and thermal vapor recompression (TVR).
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 optimized for a certain duty.
SONDEX® Traditional plate heat exchangers
SONDEX® Traditional plate heat exchangers are the ideal choice for a wide range of applications across numerous market segments. We have the largest plate portfolio in the world, and customize each heat exchanger to meet your exact requirements. Innovative technologies and smart design make our traditional plate heat exchangers a stellar investment.
SONDEX® Semi-welded plate heat exchangers
SONDEX® semi-welded plate heat exchangers are the prime choice for challenging applications that involve aggressive media or high levels of pressure. We customize each heat exchanger to your specifications, and offer durable solutions designed to withstand extreme conditions and minimize the risks of operating with chemicals or refrigerants.
SONDEX® Free Flow plates
SONDEX® Free Flow plate pattern technology is used for duties that involve hard-to-treat media and applications that have a high tendency to cause fouling in the heat exchangers. Especially advantageous for industries that run seasonal campaigns, Free Flow plates allow for extended operation without needing to shut down and clean the heat exchangers.
SONDEX® Sanitary plate heat exchangers
SONDEX® sanitary plate heat exchangers are made for applications with strict hygienic requirements and use FDA compliant materials. We care greatly about your end product, and take the necessary steps to ensure the highest output quality. Each solution is designed based on your specifications to provide the perfect conditions for your product.
The choice of heat exchanger depends on many factors. Our skilled sales engineers design the heat exchanger with the appropriate dimensions and correct specifications based on your input and requirements, to ensure that you receive a quality solution that performs optimally.
