SONDEX plate condenser

The SONDEX plate condenser is perfect for special applications where common plate heat exchangers are inadequate. They can handle large quantities of vapors and have a large inlet for the vapors. Together with the short residence time, this creates the optimum conditions for condensation, even in low-pressure evaporation applications.

Applications that require flawless performance under condensation conditions, can be easily managed with our custom brazed and semi-welded condenser solutions. When used in low-pressure evaporation applications, our specialized condenser plate design is suitable for use with large volumes of vapors, while the plates retain their heat output.

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.
