Semi-welded Plate Heat Exchangers are commonly used as evaporators, condensers, desuperheaters, or oil coolers and are designed for heating and cooling aggressive material. It also works with a wide range of refrigerants and is especially well-suited to ammonia-based applications. Semi-welded heat exchangers are employed in both organic and inorganic chemical processing where the chemicals used limit the kind of gaskets that may be used, or when the required design pressure makes fully-gasketed PHEs or traditional rubber seal heat exchangers unsuitable. We have build each heat exchanger to your exact specifications, ensuring a long-lasting solution that can endure harsh circumstances while reducing the risk of chemicals or refrigerants.
