SONDEX® plate evaporators

SONDEX® plate evaporators are designed to handle advanced evaporation duties. Using semi-welded plate cassettes, the media are guaranteed to never mix. The plate cassettes are designed to ensure the optimal level of turbulence on both sides while providing an even distribution of the media for superior performance and product quality.

SONDEX® standard, semi-welded, and brazed plate heat exchangers are outstanding choices for standard evaporation duties.

However, certain applications prove unsuitable for regular heat exchanger types. To help you obtain unsurpassed product quality, we have created exclusive evaporator plates tailored to meet the challenges presented by advanced evaporation applications

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^®plate condensers

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

Applications that demand flawless condensation conditions are easily managed using our customized standard, semi-welded, and brazed SONDEX® condenser solutions. For low-pressure vapor duties, our specialized condenser plate design accommodates large vapor volumes while maintaining the thermal performance of the plates.

Features and benefits

• Designed specifically for demanding condensation duties that benefit from a special asymmetric plate design that is unavailable for regular heat exchangers.
• Experience the high thermal efficiency of our SONDEX® heat exchangers and enjoy peace of mind with an ideal turbulent flow that reduces the risk of fouling.
• Special Multi-gap plate design that can lower the energy consumption considerably for condensation duties that differ in flow volume.

Technical specifications

• Connections from DN200 to DN800
• (Frames designed according to FEA and PED 2014/68/EU (EN13445) and ASME sec VIII, Div. 1 construction standards)
• Plate materials: AISI 304/316, titanium, SMO, Hastelloy*
• Gasket materials: EPDM-HT, NBR-HT*
• Plate heights up to 2.3 m
• Flow rates up to 800 m³/h
• Working pressure up to 16 bar
• Working temperatures from -20 °C to 180 °C
