Fishbone plate highlights Hanging system SONDEX® plates feature a reinforced hanging system. The hanging system helps the plates withstand the powerful tightening force, and prevents misalignment and corner collapses. Numerous pressing depths. This makes SONDEX® plates a solid investment, as the lifetime of the plates is increased and service duration is reduced. Asymmetric patterns available. Distribution area The distribution area on SONDEX® plates is designed to prevent stagnant zones, and ensures an even distribution of the media across the entire plate. Furthermore, the pressure drop...

Micro Plate™ highlights Individually customized As with all our solutions, we create heat exchangers that are individually customized to meet your requirements. By varying the number, size, and placement of dimples, Micro Plates™ can be adapted for optimal heat transfer and minimal pressure drop – so you decide what is best for your district heating and cooling applications. Adaptable plate design. Compact size. Even flow By allowing water to flow more evenly, the Micro Plates™ make optimal use of their surface area. Between the fastest and slowest flowing areas, the difference is only x3,...

Free Flow plate highlights Spacious channels The SONDEX® Free Flow pattern ensures an unimpeded flow due to the deep channels, and limited contact points between the plates. Very few contact points. With only line-contact, the media has ample room to flow inside the plate channels, benefiting greatly from the increased level of turbulence, compared to tubular heat exchangers. Very deep pressing depths. Asymmetric patterns available. Contact-free inlets The design of the SONDEX® Free Flow inlets maintains the sturdy and robust construction of the traditional plate design, while having no...

Free Flow plate heat When your media requires gentle treatment and sizable plate channels, SONDEX® sets the new standard for improved performance and reliability. What does that mean for you? Experience the benefit of maximum uptime and efficiency with SONDEX® Free Flow plate heat exchangers. Extended production time, and loss of product on account of unscheduled maintenance or cleaning, is an undesirable consequence of operating with hard-to-handle media. Our engineers have designed the SONDEX® Free Flow solutions to reliably deliver the highest performance and gentle media treatment,...

When your evaporation duties involve temperature sensitive or delicate media, SONDEX® is dedicated to ensure the highest product quality with our specially designed evaporator plates. What does that mean for you? The SONDEX® rising film plate evaporator gently treats the media, even if it is highly viscous, leading to improved concentrate quality. Experience first hand the benefit of using an evaporator with semi-welded plate cassettes instead of a tubular heat exchanger. Gain maximum efficiency with a plate pattern that creates the optimal turbulent flow, ensuring the best possible heat...
