Soldered plate heat exchangers are indispensable equipment in modern industry, requiring high efficiency, compact design, and leak-proof systems. These devices facilitate energy transfer between two fluids at different temperatures, particularly excelling in areas such as heating, cooling, energy recovery, oil cooling, and process control. They are produced by combining a series of metal plates with special solder materials in a vacuum environment. This manufacturing method ensures that the device has a gasket-free and completely leak-proof body.
Thanks to their compact design, soldered exchangers can achieve high heat transfer even in narrow spaces, and they also stand out with their high pressure and temperature resistance. Risks such as leakage or maintenance needs that can be seen in traditional gasketed exchangers are minimized in soldered types. Therefore, they are used in a very wide range, from HVAC systems to power plants, and from the food industry to the maritime sector.
The reasons for the preference of soldered heat exchangers include the following:
• Compact Design: Offers the same capacity in much smaller sizes compared to classic tubular or gasketed exchangers. This feature provides a significant advantage, especially in systems with limited space and mobile applications.
• High Heat Transfer Efficiency: Thanks to the special surface geometry of the plates, the fluids flow in a turbulent regime, which increases the heat transfer coefficient and minimizes energy loss.
• Leak-proof Body Structure: The soldered manufacturing technique eliminates the need for gaskets; this ensures complete leak-proof performance even under high pressure, temperature, and vibration.
