Danfoss Sondex Semi-Welded Plate Heat Exchangers

Our SONDEX® semi-welded plate heat exchangers are the prime choice for challenging applications that involve aggressive media or high pressure. The semi-welded plate heat exchangers are very versatile which means that they can easily be configured for use in different industries and applications that involve challenging media, such as chemical processing. We customize each heat exchanger according to your specifications and offer durable solutions designed to withstand extreme conditions and minimize the risks of operation. You can safely operate with hazardous or aggressive media, high pressure, or extreme temperatures that are unsuitable for regular fully gasketed heat exchangers. We design to give you peace of mind.
