SONDEX® Semi-Welded heat excanger

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.

Features and benefits

  • High efficiency means that fewer plates are needed for high performance and consequently lowers the hold-up volume. Fewer plates also lowers the cost of each heat exchanger, as an added bonus.
  • Engineered to use smaller amounts of potentially hazardous media, the SONDEX® semi-welded range is a safe and responsible choice for demanding duties.
  • Unique gasket system intended for high working pressures and vacuum applications. A closed gasket groove keeps the gasket firmly in place and prevents misalignment of the plate pack during assembly and operation.
