Plate heat exchangers, with their compact and modular design, provide great convenience in both assembly and maintenance. Especially in gasketed types, the correct selection of components directly affects the efficiency and lifespan of the device. Therefore, knowing which parts are used during assembly and their functions is essential.
Main Components
• Plates → These are the primary surfaces where heat transfer occurs. They are made of materials such as stainless steel or titanium. Specially patterned plates increase turbulence of the fluid, thereby enhancing heat transfer efficiency.
• Gaskets → Provide sealing between the plates. Gaskets made of EPDM, NBR, or Viton are selected according to the operating temperature and pressure of the exchanger.
• Compression Plates → Securely hold the plate pack in place. They are usually made of carbon steel, with epoxy-coated or stainless steel options available.
• Connection Nozzles → Form the inlet and outlet points of the exchanger. Flanged or threaded connections allow easy integration into the piping system.
• Tie Bolts → Hold the plates and frame together. They can be quickly removed and reinstalled during assembly and maintenance, minimizing system downtime.
Optional Components
• Insulation Jacket → Can be added optionally to prevent energy loss and increase efficiency.
• Cleaning Connections → Provide suitable connections for CIP (Cleaning-In-Place) systems, making regular cleaning easier.
In Brazed Heat Exchangers
In brazed exchangers, there are no assembly parts. These units are manufactured as a single piece and cannot be disassembled. Thanks to their compact structure, they can be directly mounted into the line with flanged or threaded connections. This feature minimizes maintenance needs while making them suitable for high-pressure and high-temperature applications.
Visualizing the differences between plate and brazed heat exchangers helps readers understand which type of exchanger is more suitable for their needs.
