Introduction to Semi – welded Plate Heat Exchangers
Semi – welded plate heat exchangers are a type of heat exchanger that combines the advantages of welded and gasketed plate heat exchangers. In a semi – welded design, pairs of plates are welded together to form channels for one fluid, while the other fluid flows through the channels separated by gaskets. This design provides excellent resistance to high pressures and temperatures, as well as the ability to handle corrosive and aggressive fluids. Semi – welded plate heat exchangers are widely used in various industries, such as chemical, food and beverage, power generation, and HVAC, due to their high efficiency, compact size, and ease of maintenance.
