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. We customize each heat exchanger according to your specifications and offer durable solutions designed to withstand extreme conditions and minimize the risks of operating with chemicals or refrigerants.

Product description

SONDEX® semi-welded plate heat exchangers

Our SONDEX® semi-welded plate heat exchangers are perfect for ammonia-based applications, but can easily handle most refrigerants. Primarily used in the cooling and refrigeration industry, they are commonly installed as evaporators, condensers, or oil coolers, but their versatility means that they can easily be configured for use in other industries and applications that involve challenging media, such as chemical processing.

With our solutions, you can safely operate with hazardous, aggressive media, high pressure, or extreme temperatures that are unsuitable for regular fully gasketed heat exchangers. We design to give you peace of mind.

What does that mean for you?

Our SONDEX® semi-welded range does away with off-the-shelf heat transfer solutions and offer customized heat exchangers tailored to your individual application. Enjoy a service-friendly semi-welded plate heat exchanger that is easy to install and provides top-tier thermal performance.

Safe Operation

For increased safety, the semi-welded product range uses cassette technology instead of regular plates. Each cassette features a gasketed side for the harmless/non-aggressive media, and a welded side for the aggressive media. With alternating gasketed and welded channels the media are guaranteed to never mix.

The welded side holds a custom, damage-resistant ring gasket. With a considerable reduction of the exposed gasket area, our semi-welded plate heat exchangers have a long product lifetime and provide safe, leak-free operation.

Our extensive experience and deep process knowledge allow us to avoid the common pitfalls of complicated applications and deliver reliable, high-performance heat exchangers.

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.
